Entity Framework beta 2 is up!

Over here: http://www.oracle.com/technetwork/topics/dotnet/downloads/oracleefbeta2-421283.html
Readme here: http://www.oracle.com/technetwork/topics/dotnet/downloads/odpnet-1120240-beta-readme-404197.html
It's not posted on any of the websites that I've seen yet, but you can search for the build number and find the download. Finally I can replace all those "decimal" types. :)

I dunno. The readme says it's explicitly not supported in beta 2... but if you're using DB First and use the DbContext object generator on the model it actually works pretty well. I've got a project doing that running right now.
Hopefully it gets officially supported by the release, but even if it doesn't I'm probably going to use it. :D

Deploying LightSwitch applications to IIS using the Oracle Entity Framework

I have had no sucess running Lightswitch applications on IIS using the Oracle Beta entity framework. Applications work fine from visual studio but after deployment fail when I trying to access an Oracle data entity.
I have tried deploying to a 2008 V2 server 64Bit running IIS7.5 and also to a 32 bit windows 7 machine running IIS7. Both machines had the entity framework installed and I could connect to Oracle with SQL developer just fine. Briefly in the case of the 64 bit machine I get a bad image exception indicating a 64/32 bit conflict. (App pool switched to allow 32bit). The problem with the 32Bit machine is that the session either hangs or dies with an [Arg_TargetInvocationException]
In all tests apps could connect to SQL server fine but as soon as I use an Oracle connection they fail. It would very helpfull if someone could confirm that they have managed to use the Entity framework Beta with Lightswitch and IIS.
Thanks in advance

Both hosts working now. Initially I created a service account for the aspnet service with extended rights and assigned this to the application pool. This subsequentluy turned out not to be required - ApplicationPoolIdentity works fine. What worked was as follows:
1. On a 64 Bit host you need to set the application pool to Enable 32 Bit Applications (Right click the relevant app pool in IIS and select advanced)
2. Switch off windows authentication for the application (leaving just anonoymous authentication) This was required on both hosts
3. On the 32 Bit host copy tnsnames to the oracle client admin folder - the framework seems to ignore theTNS_ADMIN environment variable. Probably more to this but its working for now.

Entity Framework vs NHibernate, which is better

I currently use ADO.Net and I would like to switch to Entity Framework, but my co worker uses NHibernate and says its more mature than Entity Framework. I just wanted to get opinions on the difference between the two and which one is better (easier to use, better performance, etc)chuckdawit

I have nothing against nHibernate. I have worked with it in 3 shops. In
one shop, nHibernate was an absolute dog, and it was dead slow. In the
other shop nHipernate was ok with the speed and was using Afluent.
However, in both of those shops nHibernate was a PITA to deal with, and
one had to build all those objects by hand. The other shop had a 3rd
party version of nHiberate that had a designer that built the objects,
but it was too slow, and the shop went back to ADO.NET and T-SQL/

Where can I download ODAC 11.2.0.2.50 Beta for Entity Framework?

Hello,
An application I have been developing during the last quarter of 2011 was using ODP.NET 11.2.0.2.50 which was the last beta version with Entity Framework support before final release. I would like to upgrade to Release 4 now but unfortunately it is not likely to happen with the actual project. Problem is that since I lost the installer for both 32 and 64bits versions and that the download is not available on the Oracle Downloads website anymore I can't deploy the application on new machines.
The name of the file was ODAC1120250Beta_EntityFramework_32bit.zip but I can't find it anywhere on the web or only leads to dead links. Would appreciate a bit of help on that.
Thank you.
Lionel.

So what can i use rather then 11.2.0.2.50 that will be supported for entity frame work
i used "ODTwithODAC112030" but it is not supported by ADO. net entity model framework.
my problem:
i made a entity model but i cannot access data from oracle database.Nothing show in the client side data grid.

CRVS2010 Beta - WPF / Entity Framework example?

Has anyone been successful integrating Entity Framework objects into the CR WPF viewer? The designer seems to work, but all we get is a blank page. Trying to load the entities directly runs into trouble from the "not-nullable" problem and the nullable custom entities don't shoe up in the field selector (not sure why).
If you can share a positive experience, we'd appreciate it.

I've been able to produce a report of our Entity Framework data by moving the data into local objects. The WPF Report Viewer seems incapable of referring to classes in other projects of the solution. More importantly when I try to use the Database Expert to use certain objects (tables) which link to each other through foreign keys, I am unable (because of viewer errors) to display the report. Is anyone else working in a similar environment?

Adding Entity Framework Crashes Visual Studio 2010/2013

I'm having problem with using the Entity Framework version 6/5. Whenever, I create the new solution and try to use the Entity Framework, Visual Studio crashes and restarts itself. Scenarios are:
1) Add Entity Framework by Add New Item-> Entity Framework-> go through wizard and finish...Crash.
2) Add by Nuget console-> Install-Package Entityframework...Crash.
3) Reload the solution from either #1 or #2, run Nuget console->Uninstall-Package Entityframework...Crash
4) new solution, nuget package manager, select Entity Framework->Install...Crash.
No matter what I do, and how I try to install entity framework, it keeps crashing on both VS 2010 and VS 2013. It's frustrating when I'm trying to learn the technology. Below are the Application error log I see in the Event Viewer:

Calling Oracle stored procedure with out param of user define type from Entity Framework 5 with code first

Guys i am using Entity Framework 5 code first (I am not using edmx) with Oracle and all works good, Now i am trying to get data from stored procedure which is under package but stored procedure have out param which is user define type, Now my question is
how i will call stored procedure from entity framework
Thanks in advance.

I agree with you, but issue is we have lots of existing store procedure, which we need to call where damn required. I am sure those will be few but still i need to find out.
If you think you are going to get existing MS Stored Procedures or Oracle Packages that had nothing to do with the ORM previously to work that are not geared to do simple CRUD operations with the ORM and the database tables, you have a rude awakening
coming that's for sure. You had better look into using ADO.NET and Oracle Command objects and call those Oracle Packages by those means and use a datareader.
You could use the EF backdoor, call Oracle Command object and use the Packages, if that's even possible, just like you can use MS SQL Server Stored Procedures or in-line T-SQL via the EF backdoor.
That's about your best shot.

Multiple database users, ORM, entity framework, best practices

Hello everyone!
You've already helped me several times, however I must ask for an advice once more.
I was assigned to develop .NET application with Data Access Layer and I've decided to use Oracle Database Software to provide sample data.
As I'm absolute novice considering creating DAL I'd be grateful if you can examine my plan in terms of security and reliability:
My database:
1) I've created database with sample tables and relations between them. All tables belongs to databaseAdmin.
2) I've created HR and Manager database users and granted them some privileges on certain databaseAdmin's tables. My intention is to reduce access to unnecessary tables. If my application user want to make some changes to Customers table it should be enough to connect to database as HR.
And now I'd like to map my database using Entity Framework in my application. And that's where I have a problem:
-If I create Entity Model basing on databaseAdmin tables I get perfect model, however every Entity SQL query would be executed on behalf of databaseAdmin, which breaks my idea of hiding unnecessary tables.
-If I create Entity Model for HR and Manager users, my models could overlap on tables that both users have access to and no connection between tables would be generated (as from their point of view those tables are just some tables that belong to databaseAdmin)
Could you help me with this deadlock? Or maybe my assumptions about multiple database users are incorrect? Please, bear in mind I'm a novice.
I was trying to find a solution in web, and there're tons of data discussing technical aspects of Entity Framework etc., but not so many documents about conceptual model of database.

hi Michael,
Thanks for you posting!
Sorry for I am not totally understanding your issue. Maybe two points need your confirm:
1. I confuse with the "Service controller"? IS your meaning MVC controller? Or ServiceController(http://www.codeproject.com/Articles/31688/Using-the-ServiceController-in-C-to-stop-and-start
2.whether The type of ID in the model is match to the database ? In other words, Is the type of IDin .edmx matched to the database?
By the way, it seems that this issue is more related to EF. You could post this issue on EF discussion for better support.
Thanks & Regards,
Will

Custom mapping is obviously not reflected in the Entity Framework designer

Hi,
I use the Oracle Data Provider for .NET 11.2.0.2.50 Beta 3 with the Entity Framework. I added a custom mapping to the app.config that maps NUMBER(1,0) to bool:
<oracle.dataaccess.client>
<settings>
<add name="bool" value="edmmapping number(1,0)" />
</settings>
</oracle.dataaccess.client>
When I create an Entity Framework model from my Oracle database the EF designer uses Int16 for NUMBER(1,0) fields instead of bool. If I run the program I then get an exception (as expected):
"Schema specified is not valid. Errors:
EntityFrameworkTest.msl(7,12) : error 2019: Member Mapping specified is not valid. The type 'Edm.Int16[Nullable=True,DefaultValue=]' of member 'ISVIPCUSTOMER' in type 'EntityFrameworkTestModel.CUSTOMER' is not compatible with 'OracleEFProvider.number[Nullable=True,DefaultValue=,Precision=1,Scale=0]' of member 'ISVIPCUSTOMER' in type 'EntityFrameworkTestModel.Store.CUSTOMERS'."
Okay. Assuming it's an error in the EF designer, I set the type Boolean in the model myself for the NUMBER(1,0) fields. But that gives me a compilation error:
"Error 2019: Member Mapping specified is not valid. The type 'Edm.Boolean[Nullable=True,DefaultValue=]' of member 'ISVIPCUSTOMER' in type 'EntityFrameworkTestModel.CUSTOMER' is not compatible with 'OracleEFProvider.number[Nullable=True,DefaultValue=,Precision=1,Scale=0]' of member 'ISVIPCUSTOMER' in type 'EntityFrameworkTestModel.Store.CUSTOMERS'."
Is this a bug in the provider? Or am I missing something?

Are you using model first or database first? If you're using database first, make sure you update the model from the database after adding that configuration.
Also, if your model is in a different assembly (ie a different project) from your executable, your executable project's configuration file also needs the mapping section.
Finally... there's been a LOT of threads about this not working properly in beta 3. I'm still on beta 2 and except for some incorrect error messages in the designer it works fine (I get fake errors). If nothing else works, I might suggest trying beta 2 as a last resort.

How to create ViewModel in an MVVM application using entity framework where database has many-to-many relationship?

I have started developing a small application in WPF. Since I am completely new to it, to start with I took a microsoft's sample available at
Microsoft Sample Application and following the pattern of the sampke I have been so far successful in creating four different views for their corresponding
master tables. Unfortunately, I have got stuck up as the sample does not contain pattern for creating ViewModel when there is a many-to-many relationship in the database. In my application, I have the following data structure:
1. Table Advocate(advId, Name)
2. Table Party (partyId, Name)
3 Table Case (caseId, CaseNo)
4. Link Table Petitioner (CaseId, PartyId)
5. Link Table Respondent (CaseId, PartyId)
6. Link Table EngagedAdvocate(CaseId, advId)
7. Link Table EngagedSrAdvocate(CaseId, advId)
In the scenario above, I am a bit confused about how to go forward creating the required ViewModel which would render me to have multiple instances of Petitioners, Respondents, Advocates and SrAdvocates.
Please explain details in step by step manner considering that whatever work I have completed so far is a replica of Microsoft's sample referred above. I would also like to mention that I have developed my application
using VB.net. So please provide solution in vb.net.
After getting many-to-many relationship introduced into my application, it would achieve one level above the sample application and I would like to share with the community so that it could be helpful to many aspiring developers seeking help with MVVM.

Hi ArunKhatri,
I would suggest you referring to Magnus's article, it provides an example of how you could display and let the user edit many-to-many relational data from the Entity Framework in a dynamic and data-bound DataGrid control in WPF:
http://social.technet.microsoft.com/wiki/contents/articles/20719.wpf-displaying-and-editing-many-to-many-relational-data-in-a-datagrid.aspx
You can learn how to design the ViewModel and the relationship between the entities.

Entity Framework doesn't create the database in SQL Server Management 2012, instead it just creates in (localdb)\v11.0 How to fix it?

Hi, I'm Begginer in Entity Framework. Then I'm having some problems.
I created my entities and I give Save Changes. (Ok)
Then, I Tried to Connect with the database through Server Explorer, if I use the instance of the SQL Server Management Studio 2012(PC-PAULO\INSTANCIAPJ) as Server Name, the database doesn't appears but, if I use the the instance (localdb)\v11.0 the dabase
appears.
How to change the save to the SQL Server Management Studio 2012, I don't know where this (localDB)\v11.0 saves.
Help-me Thank you :D

Hello PauloJos,
The code should be ok and it is really strange that the database is only created into the local database in your machine. I am wondering if it is related with the machine environment, could you please have a try with below demo on your machine which works
on my side and if it is possible, please have a try to run your application on other machines to see if it works:

using (CFDbContext db = new CFDbContext())
db.Database.CreateIfNotExists();

public CFDbContext() : base("UltraFoda3") { }
public DbSet<TestOne> TestOnes { get; set; }

WCF Data Service from Entity Framework 5 in SharePoint 2013

not sure which forum is best, so im going to throw it in here.
I am working on a proof of concept. I want to create a WCF Data Service within sharepoint 2013. not only do i want to do that, i want to use the Entity Framework 5 to expose the data via OData. Now, I have crawled the internet and seen various examples of
how to create wcf data services and wcf services in sharepoint 2010/2013. and have tried to apply those as needed to create this POC. So.. what I have done so far.
MonitoringData.cs
[BasicHttpBindingServiceMetadataExchangeEndpoint]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
[System.Runtime.InteropServices.Guid("0185abf6-e8b8-42e2-9965-6bb644338077")]
public class MonitoringData : DataService<MonitoringServiceEntities>
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
// TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
// Examples:
config.SetEntitySetAccessRule("*", EntitySetRights.AllWrite);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;
MonitoringData.svc:
<%@ServiceHost Language="C#" Debug="true"
Service="$SharePoint.Type.0185abf6-e8b8-42e2-9965-6bb644338077.AssemblyQualifiedName$"
Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressDataServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
upon deployment, this error when hitting the https://server/_vti_bin/poc/monitoringdata.svc/$metadata
"The type 'xxxxxxxx', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could
not be found."
Breaking out the google-fu, i found that adding the dll to the <compilation> section was needed for the web.config. so i did that. and now i just get a blank screen with no errors.
so i crack open fiddler. i see the following
200 http
tunnel to
server:443 0
401 https
server /_vti_bin/poc/monitoringdata.svc/$metadata
16
401
https server
/_vti_bin/poc/monitoringdata.svc/$metadata
0
404
https server
/_vti_bin/poc/monitoringdata.svc/$metadata
0
best i can see is that im either not authorized, and its returning null (which shouldnt be the case) or something is just busted.
The goal is to use ntml auth and https to connect to this service. any ideas?

One thing I found was that it's never worth the trouble to place the WCF service in a web site running SharePoint, it's better to place it in a dedicated web site, as described in this article:
http://sharepointdragons.com/2011/10/07/parallel-programming-in-sharepoint-2010-the-back-to-the-future-pattern/
It's usually too much work to get the web.config settings right because of the settings it inherits from its parents.
Kind regards,
Margriet Bruggeman
Lois & Clark IT Services
web site: http://www.loisandclark.eu
blog: http://www.sharepointdragons.com
I'll say that it is one solution to move the WCF Service outside of sharepoint. but my "1000 mile" requirements makes this a necessity.
To broaden the scope of what I am doing, I have a custom SharePoint Service Application. this custom application has a proxy that used a restful interface. Now, with all the methods i will have to write (over 100, x3 for all of the "proxy to a proxy" scenarios)
I wanted to explore the idea of using odata. so i can use the various clients to write their own queries instead of me writing them all and exposing them. especially since its all linq queries to a database underneath. I feel that I am missing some specific
component to make this work, and its surely due to my incomplete knowledge of WCF or EF.

Update the database structure from entity Framework Model

Hello !
I'm using VB.net , EF6 with SQL server 2008R2 database.
This is the situation :
I have created the application. Using wizard I have created the Entity model from an existing database.
A client start using this application using this database on his computer.
After some month , I made some modifications on the database and I have updated the model on my application .
Now I have a new .exe file that has the new model from the new database.
I put the new .exe file on the client computer.
Now on his computer : The .exe file has the new database model , but the sql server database has the old structure.
I want to know : Is possible to update the database structure from the entity model on application ?
I want to add a command on application that can make ( if is possible ) this update , so the database become up to date according to entity model ?
Thank you !

Hello,
From your description, it seems that you want to apply a migration for a database first approach, unfortunately, as far as I know, EF Migrations is a product targeted at Code First and doesn't support Database First operations. A workaround I know is to
use update-scripts. If your database structure would be changed frequently, it is recommended to use the Code First approach which would have a better workaround for migrations, for details, you could refer to this
video,
and with the
Entity Framework Power Tools, it is easy to create a code first based project form an existing database.

Best Practices for Using Service Controller for Entity Framework Database

I'm running into an issue in my first time creating a Web Service with a .NET backend with Azure. I designed a database in Entity Framework and had it create the models, but I couldn't create a controller for the table unless I made the model inherit from
EntityData. Here's the catch, the Database Model has int Id, but EntityData has string Id, so, of course, I'm getting errors. What is best practice for what I'm trying to do?
