Thanks in advance.....

Hi Shivaprasad,
Check .net version in your project properties, If it isset to .net 2.0, change it to .net version to 3.0 and it should work.
Let me know if it works or not..

Could you guide me how to resolve the above error's ?
Thanks in Advance...

Hello Divakar Ponnada,
I have checked the error CS0234 from here:
http://msdn.microsoft.com/en-us/library/0e92xd7b.aspx
It means your project cannot find the proper reference to your type "Visual Studio" from the namespace Microsoft.
May I ask this question, does your build definition means something like the following blog described?
http://www.asp.net/web-forms/overview/deployment/configuring-team-foundation-server-for-web-deployment/creating-a-build-definition-that-supports-deployment
"A build definition is the mechanism that controls how and when builds occur for team projects in TFS. "
If that is the problem, may I ask whether your build agent is in the same machine where you build your application?
The build agent will first search for the reference from its local GAC and if it cannot find it, the error like you said will reports. Please manually build your project from your build agent machine to see the result, or install Visual Studio to your build
agent machine. In that way I think your problem may fixed.
Best regards,
Barry

Error on new windows 8.1 project: The type or namespace name 'Foundation' does not exist in the namespace

I upgraded to win 8.1 and VS 2013. I created a new Windows 8.1 C# grid project and tried to compile it and I'm seeing the following error: Error 1 The type or namespace name 'Foundation' does not exist in the namespace [my namespace](are

Windows phone and mvc projects are working fine and I've installed all the updates and even tried to fix vs 2013.
Any help Is greatly appreciated.

I did some more investigation and noticed that if I create an app with a "." in the name then this problem occurs. For example create a windows store project with the default name "App1": this will compile.
However if I name the project "App1.Forms" to correspeond with the default namespace I want, then this problem occurs. Still investigating but anyone should be able to repro it with that step.

Hi,
Just confirm that Target Frame work has been changed to 4.5 or not, if not changed it to 4.5 and give it a try. Then also it gives error then check the SP reference, dll properties and check its version(it should be 15.0.).
PS:-You can fine target framework under project properties->Application-> Target Framework.

The type or namespace name 'Reporting' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

I have a Windows app that was built some 7 years ago on a WinXP machine using VS2005. It uses Crystal Reports for the reporting. We recently got new machines with Win7 x64 and I installed VS 2013 Pro. I moved the app to my machine and upgraded
it to that VS version. It previously had a .NET Framework target of version 2.0. I changed the target to version 4.5.
I want to use the MS Reporting instead of Crystal Reports. However, I cannot get the ReportViewer control to show up in the Toolbox.
I downloaded and installed the ReportViewer Runtime 2012. I installed the ReportViewer using the NuGen GUI and console. I tried adding the control to the Toolbox using Tools > Choose Toolbox Items... but it never shows up after I browse to
the Microsoft.ReportViewer.WinForms.dll file and select it. I manually typed 'Microsoft.Reporting.WinForms.ReportViewer' and the intellisense came up fine. But when I build the project I get the error shown in this post's title.
I'm at a complete loss. I've searched all over and tried everything I can find on the subject with no luck.
Can anybody help?
Thanks.

Thank you for taking the time.
The Report Viewer will not appear on the Toolbox, even with references to that assembly. However the Crystal Reports viewer IS in the Toolbox.
I think it may be because Crystal Reports is installed and integrated? I don't know. I just can't get it to work.
Thanks again.
Hello,
From
ReportViewer Controls (Visual Studio), we could get that ReportViewer Controls are included in VS2013, that means we don't need to install that control manually.
To confirm whether this issue is related to your Visual Studio or Crystal Reports, I would recommend you consider testing it with the following ways.
1. Create a simple windows form application, and open a form designer window, and check whether reportviewer is inside the tool box.
If it is available, then we could focus on your project to narrow down this issue.
If it is still missing, we could test it with #2.
2. Uninstall Crystal Reports and disable all add-ins of VS2013, and if possible, you could also uninstall and reinstall VS2013 to make sure the environment is clean enough. Next repeat the steps of #1.
It will be much helpful if you could share the detailed results with us.

Carl

Did you try to build the application (Project->Build in Visual Studio) ? If the error doesn't go away then and you have no other compilation errors (if you do you need to fix these first), you should replace "FolderExplorer" with the namespace
in which the Folder class resides. If you haven't explicitly declared a namespace, you will find the name of the default namespace under Project->Properties->Root namespace. Copy the value from this text box to your XAML:
xmlns:my="clr-namespace:FolderExplorer"
The default namespace is usually the same as the name of the application by default so if your application is called "FolderExplorer" you should be able to build it.
If you cannot make it work then please upload a reproducable sample of your issue to OneDrive and post the link to it here for further help.
Please remember to close your threads by marking helpful posts as answer and then start a new thread if you have a new question.

<ms:VisiableConverter x:Key="VisiableConverter"></ms:VisiableConverter>
</UserControl.Resources>
How to solve?
namespace DictionaryApp.Model
public class VisiableConverter : IValueConverter
public object Convert(object value, Type targetType, object parameter, string language)
throw new NotImplementedException();
public object Convert(
object value,
Type targetType,
object parameter,
CultureInfo culture)
bool visibility = (bool)value;
return visibility ? Visibility.Visible : Visibility.Collapsed;
public object ConvertBack(object value, Type targetType, object parameter, string language)
throw new NotImplementedException();
public object ConvertBack(
object value,
Type targetType,
object parameter,
CultureInfo culture)
Visibility visibility = (Visibility)value;
return (visibility == Visibility.Visible);
Next, add the converter in the UserControl's resources. In m
y simple project, I had to create this section - but hopefully you're already using this in your real apps!
You may also need to add an xmlns attribute in page.xaml for your project's namespace.
x:Class="DictionaryApp.PageDictionary"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:DictionaryApp"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:ms="using:DictionaryApp.Model"
mc:Ignorable="d">
<UserControl.Resources>
<ms:VisiableConverter x:Key="VisiableConverter"></ms:VisiableConverter>
</UserControl.Resources>

I think the not implemented exceptions could be causing the issue. I would implement this functions also
public object Convert(object value, Type targetType, object parameter, string language)
throw new NotImplementedException();
and
public object ConvertBack(object value, Type targetType, object parameter, string language)
throw new NotImplementedException();

Visual studio 2012 the name "initializeControl" does not exist in the namespace in visual WebPart

Hi All,
I'm trying to create a visual webpart in SharePoint 2013 using Visual Studio 2012 and I am seeing that the file ascx.g.cs
is missing and i have this error in file ascx.cs : the name "initializeControl" does not exist in the namespace.
And like i said i use VS2012 Ultimate
Can anyone Help me please!!!
thanks.

In most scenarios this is caused by some error in code preventing Visual Studio from generating the designer file. You could try to undo the latest changes and see whether the item is being generated or not. Additionally you could try checking if the custom
tool is still associated with the Visual Web Part SPI in the Properties Window.

Build Error : The name "LocalizedStrings" does not exist in the namespace

I have localised my app to 5 languages, it builds and runs perfectly in Silverlight, but when i open the project in Blend to make changes
it shows the following error
The name "LocalizedStrings" does not exist in the namespace "clr-namespace:appname".
Since it is bound, i need to build it, only then the text is visible :(
Any suggestions?

This is the declaration for the LocalizedStrings.cs
namespace LoveCycles_Free
public class LocalizedStrings
public LocalizedStrings()
private static LoveCycles_Free.AppResources localizedResources = new LoveCycles_Free.AppResources();
public LoveCycles_Free.AppResources LocalizedResources
get
return localizedResources;
And this is my App.xaml

The name "Pi" does not exist in the namespace "clr-namespace:PressureVessels".

Pi is the name of a class.
I made some major modification to the program in VS 2013, then after transferring the program to another PC with VS 2012 running, I am getting many errors that says:
The name "ClassName" does not exist in the namespace "clr-namespace:PressureVessels".

Cleaning removes all the stuff out your bin.
If all this stuff is in the one solution then that's equivalent to manually deleting it.
If your app is composed from separate dll then I maybe some versioning issue.
If not and you can't reproduce the issue on your dev machine...
Tricky.
You would have mentioned it if you were putting stuff in the GAC.
Could be a sln or csproj issue.
They occasionally corrupt.
What else.
How did you get your code onto the other pc?
Is it contained within one folder with no external references beyond .net framework ones?
If you did something a bit dodgy with your references a dll might be coming from somewhere which is on your pc and not on this other one.
The only other advice I can think of is to step away for a bit and do something else.
It's all too easy to get into a flat spin when something drastic happens and one has no idea wtf is going on.
I used to be a points hound.
But I'm alright nooooooooooooooooooooooooooooOOOOOWWWW !

No matter what I've tried to do with my webpart, the VS still generates an ASCX.G.CS file with no content at all. What I'm doing wrong?

Azure - The name 'model' does not exist in the current context

I am getting the error below but only on Azure, everything builds and runs fine on multiple machines running locally. But when I deploy to Azure I get the error below trying to login. Not even sure where to start researching this one
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0103: The name 'model' does not exist in the current context
Source Error:
Line 1: @model Web.Models.LoginViewModel

hi,
From the error message, it seems like a MVC issue.
I suggest you could re-configure your web configuration follow those solutions The name 'model' does not exist in current context in MVC3
and
Razor View throwing “The name 'model' does not exist in the current context” .
And then you could try to deploy project to azure again. I think this error may be disappeared. Please try it.
