[Solved] Method 'GetProjectWrap' does not have an implementation

[Telerik Admin]

Since the Telerik UI Extensions for ASP.NET MVC Q1 2011 SP1 release (v 2011.1.414) you might start getting an error, saying

Method 'GetProjectWrap' in type 'Telerik.MVC.VSX.ProjectConfigurator' from assembly 'Telerik.MVC.VSX, Version=2011.1.413.0, Culture=neutral, PublicKeyToken=0dfdc51bd06071b4' does not have an implementation.

We identified that the problem is related to having both Telerik MVC VSExtensions and Telerik WebUI VSExtensions installed on the machine. The two packages use common assemblies having different versions, which is causing the error.

We are working on finding the actual reason and a decent fix for the problem, but in the meantime you could download the attached VSIX packages, and install them to your Visual Studio instead.

Please, excuse the inconvenience.

I have encountered this problem but the replacment files provided do not cure it.  Is there anything else I need to do?

[Erjan Gavalji]

Hi Mike,

Sorry about that. Can you check the versions of all the Telerik VSExtensions using the Tools -> Extension Manager menu in Visual Studio?

Can you upgrade them with their latest versions in the Visual Studio Online Gallery?

Kind regards,

Thanks, that worked.

I used the Extension Manager to download and install the updated WebUI extensions.

I have the entire 2011-Q1Telerik Suite installed in VS2010 and had the same problem when trying to create a new "Telerik WinForms" application.

I first tried using VS2010's "Tools | Extension Manager | Updates" mechanism to do the update as Mike had said worked for him.  That only gave me a message that "No updates were available".

But manually downloading the Telerik.Web.UI.VSPackage.vsix extensions from the VS Gallery and installing them also cured my issue; at least in terms of being able to create a new Telerik WinForms app.

Hi Bob,

Thanks for sharing that!
There is a slight glitch in the tool Visual Studio uses for VSIX unpacking (vsixinstaller.exe). It happens that if Visual Studio is started during a VSIX unpack, sometimes the files of the previous VSIX package don't get removed successfully.
That often leads to broken VSIX installations.

To avoid that we added a requirement to the latest RadControls installations that Visual Studio is closed. I hope that will help avoid this upgrade bug in the future.

I am getting below error when i try toconvert MVC 2 project to Telerik MVC3 using Telerik MVC UI Extentions -> Convert to Telerik MVC Application (i.e right click on project MVC2 project)

Could not load type Telerik.VSX.WizardEngine.Configuration.ConditionInfo from assembly Telerik.VSX.WizardEngine, version=2011.1.315.0, culture=neutral,PublicKeyToken=...

I installed Telerik MVC Q2 also updated both Telerik MVC VSExtensions version 2011.2.719.0

FYI: I tried with another sample exiting project which worked fine, but still not working for above main application
Please advice, if this is a bug please let us know the work around

Hi Kalli,

I guess the VSIXInstaller (part of Visual Studio, taking care of the VSIX package activation) might have misbehaved. Can you please, perform the following for a diagnostic?

1) Start a Command Prompt and run the following two commands:
dir /s %localappdata%\Microsoft\VisualStudio\10.0\Extensions\Telerik > C:\TelerikVSExtensionsAppData.txt
dir /s "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Telerik > C:\TelerikVSExtensionsVSInstallDir.txt"
(Note, the path in the second command might be different depending on if your machine is a 64-bit or a 32-bit one and if you have installed Visual Studio on a specific path)
2) Run a Windows Explorer, pack the two txt files that got created in the C:\ drive and use a support ticket to send it to us, please.

By the way, you could try the following steps for a complete reset of the VSExtensions too:

1) Close all Visual Studio instances
2) Use Windows Explorer to check the following two folders for Telerik subfolders and delete them:
    %localappdata%\Microsoft\VisualStudio\10.0\Extensions
     [VisualStudioInstallDir]\Common7\IDE\Extensions
3) Visit the Visual Studio Online Gallery and download the Telerik MVC VSExtensions to a folder of your choice
4) Start a Visual Studio 2010 Command Prompt As Administrator and navigate to the folder you downloaded the VSIX file to
5) Run the following command:
    vsixinstaller /a [TelerikMVCVSIX_FileName.vsix]
6) Repeat steps 3) -> 5) to get any other Telerik VSExtensions you need added to your IDE.

Yes, It is working now after performing your steps.After performing the upgrade wizard i got the below warning

 USAssureDotCom Resource Copy Scripts files. Success
 USAssureDotCom Resource Copy Content files. Success
 Warning:USAssureDotCom Assembly Reference Assembly Reference "C:\Program Files\Telerik\Extensions for ASP.NET MVC Q2 2011\Binaries\Mvc3\Telerik.Web.Mvc.dll" was not updated properly. This usually happens in Visual Studio 2010 when an assembly exists both in the GAC and in a local folder. Please, use the GAC reference instead.

I couldn't find the Telerik.Web.Mvc.dll from add reference(i believe this shows all the component from GAC(please check attached screenshot)
Please advice.

[Erjan Gavalji]

Hi Kishore,

The Add Reference dialog does not display the items in the GAC unless a specific registry entry is set. The Telerik MVC UI Extensions installer does not set that registry for the behavior of the IDE in terms of assembly references gets changed.

Anyways, you can check if the Telerik MVC UI assembly exists in the GAC by following the steps below:

1. Start a Visual Studio 2010 Command Prompt
2. Run the following command
   gacutil /l Telerik.Web.MVC

By the way, can you rebuild the project (though the warning) and check the version of the Telerik.Web.MVC assembly in the BIN subfolder? It could be that the detection of the actually added reference version by the VSExtensions might have not been correct (e.g. the warning is incorrect).
