Windows azure worker role cannot debug in local environment

Hi,
I'm unable to debug the worker role application in local envirnoment with windows azure compute emulator.
I receive the below error when debug the worker role.
Microsoft Visual Studio
Windows Azure Tools for Microsoft Visual Studio
The system is missing a prerequisite to execute the service. See output window for more information.
OK
In my output window the below messages have been displayed.

hi Vel,
According to the error message, I suggest you could try to use the latest version of Azure SDK and Emulator. Also, you could refer to this document via (http://msdn.microsoft.com/en-us/library/windowsazure/dn459835.aspx#BKMK_knownIssues ).
You could get the latest version form this page (http://www.windowsazure.com/en-us/downloads/ ).
please try it.

Deploy windows azure worker role

Hi,
   I've created a simple azure worker role which executes few things in the database continuously and I need to deploy this worker role to azure portal. how can i deploy an azure worker role to azure portal.
thanks,
Snegha

Hi robdmoore67,
    I deployed my worker role using the below option
Deploy using Visual Studio by linking your Visual Studio to your subscription, right-clicking the cloud project and selecting Publish; see this link for more info: http://msdn.microsoft.com/en-us/magazine/jj618299.aspx
deployment went success but my worker role is not running on the background i guess.
this is my below code on workerrole.cs
     public override void Run()
            // This is a sample worker implementation. Replace with your logic.
            Trace.TraceInformation("WorkerRole entry point called", "Information");
            while (true)
                _myService = new MYService();
                _myService .Start();
                 Trace.TraceInformation("Working", "Information");
        public override bool OnStart()
            // Set the maximum number of concurrent connections
            ServicePointManager.DefaultConnectionLimit = 12;
            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
            return base.OnStart();
but this works fine when i try to debug locally. Kindly let me know if there is any mistake.
kind regards,
Snegha

Azure Worker Role can't receive tcp connection to Port 25(Smtp)

I have an SMTPE implementation as an Azure Worker Role. I have defined two input endpoints (port 25 and port 2525). Listener at 2525 accepts tcp connections from smtp clients. However port 25 can't receive connections.
When running on emulator port 25 works fine. This issue occurs when I publish my worker roles to the cloud.
I use the same code for both. InputEndpoints are also defined the same way. The only difference is the port number.
Is there any limitation related to port 25?

hi sir,
Base on my experience, Azure platform don't support out-of-the-box mail server. So I am not sure you can use SMTP on Azure cloud service. but I recommend you could refer to the
sendgrid .Also, you can follow this documents:

What happens when Azure Worker Role VM goes down in middle of a computation process

Hi,
I wanted to know what happens if the Azure Fabric controller decides to bring down an Azure Worker Role VM during a computation process within the worker role ? Does the new VM that FC spins up start from the same place where it left off (when the VM
was brought down). As per my understanding, answer is "NO" because an Azure VM is stateless. If we want that the new VM starts from the same place where it left off, we need to save the state and read it from there, when the VM starts (probably
somewhere in the RoleEntryPoint class).
can someone please confirm my understanding ?

Hi,
You are right.
Azure PaaS instances are stateless.
If the instance that is just configured were to fail and Azure spun up a replacement instance, all the work that you have done would not carry over.
To know more about it, you might want to refer to the link provided below
http://azure.microsoft.com/en-us/documentation/articles/fundamentals-application-models/
(Refer To Section : Cloud Services )
Hope this helps !

Deploy Files In Azure Worker Role

I have a worker role that uses the MAF framework. That means I need to add assemblies that my project do not reference directly, and these files need to be in a specific folder structure(http://msdn.microsoft.com/en-us/library/bb384201.aspx).
I had the same scenario with a web role and was able to achieve this because when you package a web role, it can copy every file found in the project folder. So I had a BeforeBuild event that would copy all the files to my bin folder for my web app, and all
the files in there were packaged in my azure package.
The same thing does not apply to worker roles. Before the build I create the folder structure in the bin\config folder, I can see the structure there, but the files do not get copied in the azure package at the end. I know the usual way to achieve this is
to add a reference to those dll and set them to copy local, but that won't place the files in the required folder structure.
Another way around would be to add custom code that would load those files from azure storage, and copy them when the role is starting, but that means I need to make extra steps everytime I deploy, and make sure that the storage is updated at the same time
of my package. I was wonedring if there was any other way to achieve this. I cannot believe that this is completely unsupported. I did not create a custom framework for my add-ins, I am usign the one provided by Microsoft with the .NET framework, so I really
hope there is a way to add those files to the azure package.
Thanks, Louis

Here is what I dened up doing to achieve this:
Make a copy of the Microsoft.WindowsAzure.targets file found in the MSBuild folder to your Azure project folder. (C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Windows Azure Tools\1.6 was the folder for me)
Modify the filed you just copied to comment a part that would delete any "oprhan" file that does not belong to the role it is building. Without removing this, the file will get deleted automatically because it will detect that the project does not need it.
<ItemGroup>
      <OrphanedWorkerFiles Include="$(IntermediateWorkerOutputPath)**\*.*" Exclude="@(WorkerFiles->'$(IntermediateWorkerOutputPath)%(TargetPath)')" />
    </ItemGroup>
    <Delete Files="@(OrphanedWorkerFiles)" ContinueOnError="true" />
That can be found on line 2864 with version 1.6 of the Azure SDK. Comment it out or remove it.
Modify the ccproj file of your Azure project to point to that file instead fo the original one. The import should now look like this: <Import Project="$(ProjectDir)Microsoft.WindowsAzure.targets" />
You can then add a <Target Name="BeforeBuild"></Target> node in that ccproj file, or add before build events in that project that will copy the required file to this folder: $(ProjectDir)obj\$(ConfigurationName)\[Azure role], and replace [Azure
role] by the name of the role you want to copy these files to.
Once you've done that, you can rebuild your solution, and any files copied during your before build event will be included in your final azure package.
Cheers!

Hello,
>>: The service configuration could not be retrieved from Windows Azure for hosted service with DNS prefix 'rmsazure' in subscription id **************
Base on error message, I guess your azure service didn't get your certificate and other instances didn't have certificate to auto scale. Please check your upload the certificate on your portal management. Also, you could refer to same thread via link(
http://stackoverflow.com/questions/12843401/azure-autoscaling-block-cannot-find-certificate ).
Hope it helps.
Any question or result, please let me know.

Installing flash player msi on Azure Worker Role VM

Hi,
Trying to install the flash msi on Azure Wroker role.
Tried the following C# code:
Type type = Type.GetTypeFromProgID("WindowsInstaller.Installer");
Installer installer = (Installer)Activator.CreateInstance(type);
installer.UILevel = MsiUILevel.msiUILevelNone;
installer.EnableLog("voicewarmup", logfile);
installer.InstallProduct(installerpath, "ACTION=INSTALL ACTION=ADMIN
REBOOT=ReallySuppress ALLUSERS=\"\" ");
While locally on the emulator it worked, on the actual VM it failed:

Hi,
I'm not familiar with Azure VMs, and therefore, unfamiliar with Worker Roles in Azure VMs, however, error: 0x80070005 is the standard Microsoft error for Access Denied. Based on the log output you have, the access denied error is being returned when attempting to connect to a server.

Azure Worker Role reboots when adding instance of Web Role

I have a Windows Azure cloud service with a Web Role and a Worker Role. I I have built a website that allows me to perform various management functions against the cloud service (stop/start, reboot instance, add instance, remove instance). All functions are
performed via the web api. My issue is that when I add an instance of the web role, the worker role reboots. Note that this doesn't happen if I add an instance via the Azure portal. The code functions correctly in all other aspects. Any idea how to do this
so that only the role being affected recycles instead of all roles recycling?
My code:
public void AddInstance()
XDocument configDoc = this.GetDeploymentConfiguration();
var ns = configDoc.Root.GetDefaultNamespace();
configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value = ( int.Parse( configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value ) + 1 ).ToString();
string encodedString = Convert.ToBase64String( Encoding.UTF8.GetBytes( configDoc.ToString() ) );
this.SetDeploymentConfig( encodedString );
public XDocument GetDeploymentConfiguration()
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
var xdoc= operation.Invoke( uri );
var myelm = xdoc.Element( wa + "Deployment" ).Element( wa + "Configuration" );
var mystring= Encoding.UTF8.GetString( Convert.FromBase64String( myelm.Value ) );
return XDocument.Parse( mystring );
public string SetDeploymentConfig( string configurationFile )
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "/?comp=config" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
string payloadString = string.Format(
@"<?xml version=""1.0"" encoding=""utf-8""?>
<ChangeConfiguration xmlns=""http://schemas.microsoft.com/windowsazure"">
<Configuration>{0}</Configuration>
</ChangeConfiguration>", configurationFile );
XDocument payload = XDocument.Parse( payloadString );
return operation.Invoke( uri, payload );

Hi,
From my experience, if you add one role instance, the whole cloud service will run in translating state, and this cloud service will stop to working, so maybe this is a future request.

What actions will trigger azure worker role reboot

Hi team,
we have a application host in worker role, the worker process will create a new process if it receive a request,
i we want to update the worker and keep new process still working smoothly, what we should do during the Udate.
we did some test for this and found that when updating the worker role via portal, the worker role VM will not reboot,
will all update not cause worker role reboot?
another question, what actions will cause worker role reboot,so that we could avoid them when doing update.
thanks in advance.

Hi,
Thanks for Posting. I see that no one in the forum community has answered the question. hope the following resource points you in the right direction.
There are certain implicit and explicit factors that may force the runtime to reboot or re-launch the role instances. Implicit factors are internal to Azure environment and explicit factors are those that are initiated through the change in configuration
files or by performing an in-place upgrade.
Refer to this link :

How is a Worker Role hosted?

Hi
How is a worker role hosted in Azure. What process is it in?
I'm thinking of how to test locally or an on premise version. Is the Azure host process simply a windows service?
I'm writing a solution that uses the Service Bus for Window Server 1.1 as my customers all use on-premise servers (at the moment). It would be handy if I could create a worker role for on premise solutions :)
Thanks
Graham

Hi Graham,
Thanks for your posting!
Base on my understanding, Azure worker role is used for some services would run in the background to collect, transform, and prepare data. In other words, Azure work role could
executive function to a background processor .
In worker role project, we could see the file named "WorkerRole.cs". The class inherited the "RoleEntryPoint".
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
Trace.TraceInformation("WorkerRole1 entry point called");
while (true)
Thread.Sleep(10000);
Trace.TraceInformation("Working");
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
// For information on handling configuration changes
// see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
return base.OnStart();
When one worker role instance was starting, it could be executed "OnStart()" method firstly. Then in a worker role’s lifecycle is the "Run" method, typically implemented as an infinite loop, such as "While(true) ".
In fact, if the Run method terminated, the instance would be restarted or recycled again. Please see this video (http://channel9.msdn.com/Series/Windows-Azure-Cloud-Services-Tutorials/Introduction-to-Windows-Azure-Worker-Roles-Part-1).
For your question----" Is the Azure host process simply a windows service?", the answer is that one worker role can be one or more than one instance (VM).
And in your scenarios, Worker role could meet your requirement. In VS, Azure SDK support one project template named "Worker role with service bus queue". Please see this documents:

Can a Worker Role process call Antimalware for Azure Cloud Services programmatically?

I'm trying to find a solution that I can use to perform virus scanning on files that have been uploaded to Azure blob storage. I wanted to know if it is possible to copy the file to local storage on a Worker Role instance, call Antimalware for Azure
Cloud Services to perform the scan on that specific file, and then depending on whether the file is clean, process the file accordingly. If the Worker Role cannot call the scan programmatically, is there a definitive way to check if a file has been scanned
and whether it is clean or not once it has been copied to local storage (I don't know if the service does a real-time scan when new files are added, or only runs on a schedule)?

Hi,
I would suggest you have a look at this article:
http://azure.microsoft.com/blog/2014/10/30/microsoft-antimalware-for-azure-cloud-services-and-virtual-machines/, please note the Microsoft Antimalware Client and Service is not installed by default in cloud service, please try to use the PowerShell
cmdlet, Set-AzureServiceAntimalwareExtension to enable antimalware in your cloud service. Here's some more info:http://msdn.microsoft.com/en-us/library/azure/dn771718.aspx

Jambor

Is this the best design for asynchronous notifications (such as email)? Current design uses Web Site, Azure Service Bus Queue, Table Storage and Cloud Service Worker Role.

I am asking for feedback on this design. Here is an example user story:
As a group admin on the website I want to be notified when a user in my group uploads a file to the group.
Easiest solution would be that in the code handling the upload, we just directly create an email message in there and send it. However, this seems like it isn't really the appropriate level of separation of concerns, so instead we are thinking to have a separate
worker process which does nothing but send notifications. So, the website in the upload code handles receiving the file, extracting some metadata from it (like filename) and writing this to the database. As soon as it is done handling the file upload it then
does two things: Writes the details of the notification to be sent (such as subject, filename, etc...) to a dedicated "notification" table and also creates a message in a queue which the notification sending worker process monitors. The entire sequence
is shown in the diagram below.
My questions are: Do you see any drawbacks in this design? Is there a better design? The team wants to use Azure Worker Roles, Queues and Table storage. Is it the right call to use these components or is this design unnecessarily complex? Quality attribute
requirements are that it is easy to code, easy to maintain, easy to debug at runtime, auditable (history is available of when notifications were sent, etc...), monitor-able. Any other quality attributes you think we should be designing for?
More info:
We are creating a cloud application (in Azure) in which there are at least 2 components. The first is the "source" component (for example a UI / website) in which some action happens or some condition is met that triggers a second component or "worker"
to perform some job. These jobs have details or metadata associated with them which we plan to store in Azure Table Storage. Here is the pattern we are considering:
Steps:
Condition for job met.
Source writes job details to table.
Source puts job in queue.
Asynchronously:
Worker accepts job from queue.
Worker Records DateTimeStarted in table.
Queue marks job marked as "in progress".
Worker performs job.
Worker updates table with details (including DateTimeCompleted).
Worker reports completion to queue.
Job deleted from queue.
Please comment and let me know if I have this right, or if there is some better pattern. For example sake, consider the work to be "sending a notification" such as an email whose template fields are filled from the "details" mentioned in
the pattern.

Hi,
Thanks for your posting.
This development mode can exclude some errors, such as the file upload complete at the same time... from my experience, this is a good choice to achieve the goal.

Jambor

Flash Player in web page hosted on Windows Azure

First, I admit I am a Flash noob. That said, I have an ASP.NET web page (ASPX) hosting a flash movie, and the page works perfectly on my development box but does NOT work when hosted on a Windows Azure web role. The initial image (PNG) displays, and the triangular "play" button is there, but when you click it the player rectangle goes all black.
I have verified that the files are in place. All the naming is correct. As mentioned, it DOES work locally.
This is an SWF file that loads an MP4 file and there's some xxx_config.xml file that provides subtitles to the narration in the video. I did not make the movie, but it was made in Camtasia Studio 7. It generated the core html object tags that I copied, and all the supporting files. As far as I can determine, the SWF file is failing to load the MP4 file.
In theory, this should NOT be a cross-domain issue as all the files are in the same folder of the same web site. I have tried adding a crossdomain.xml for good measure, but that had no effect. I also made sure to try using one single web server instance in Azure in case the load balancing between instances was causing the problem, but that had no effect.
I have a support call in to Microsoft, but of course they say they do not support Flash and I imagine Adobe will say they don't support Azure.
Anyone aware of any Azure-specific gotchas?
PS I am testing in the same IE9 browser from my local machine so browser settings are identical from the case that works.

I fixed it myself. It turned out to be an Azure issue, not a Flash issue. By default when an Azure web role instance is created (think VM), the IIS server is not configured with a MIME type for MP4 files. You have to add it to your project's web.config file if you're going to use that type of file.
IIS doesn't like to serve up file types that it doesn't know about.

Worker role scale up and down manually

I have specific task that need to be done on random time (i cannot predict when). one task can take more than 5 min.
To be "cloud" compatible and "elasctic" ready, i don't want to have only 1 instance of this worker role but more dynamically when needed.
I ve created a "queue" with all the task that need to be done, because it was the solution i thoguth with the auto scalling of azure
But when i try to put it in place, my problem are the following :
1)with the auto scalling of worker role, it seems it doesn't start to evaluate directly and wait maybe 20 min before scale up the first time. it's not fully ok for me and i would like to have scaling directly.
2) one instance cannot be killed like this. The task can take more than 5 min ! (maybe 10 or 15). And in this case it's a big issue for me if one instance is randomly dropped. And i cannot can "put" somewhere the current data of the task to be proceeded
by someone else
My idea is that my instance "0" create other instance if it see that the number of task on the queue is big
AND, it's the instance created (so not the 0!) that kill itself when he has finished and see there is nothing else to do
Is it possible ? I don't find documentation about that.

Hi,
If you use auto scaling add a worker role, it spend 20 min before scale up the first time, this 20 min may be used to build azure worker role instance. so we need a metrics to let worker role prepared in advance, for example, in the case of Cloud services,
if CPU exceeds a defined threshold in your rule, auto scaling will add additional instances to handle the increased load. When CPU drops below a defined threshold, auto scaling will remove those extra instances. It’s this kind of elasticity that
makes cloud computing so compelling.
