Problem in upgrade to 2012 Q1

[max]

Hi , I have a project with 2011 Q1  , i just upgrade the project to 2012 Q1 but it has a warning :

Assembly Reference "D:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q1 2012\Bin40\Telerik.Web.UI.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.

what should I do ?

Hello,

Could you, please, upgrade the Telerik WebUI VSExtensions package in your Visual Studio to the latest version and try to upgrade once again to Q1 2012?

If the problem remains, my recommendation is to upgrade manually following the instructions provided in the following help article: http://www.telerik.com/help/aspnet-ajax/introduction-upgrading.html.

Could not load file or assembly 'Telerik.Web.UI, Version=2011.1.315.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Hi,

I think the following KB article might help you solve the problem:
Error: Could not load file or assembly 'Telerik.Web.UI, Version=XXXXX.X.XXXX.X, Culture=neutral, PublicKeyToken=XXXX' or one of its dependencies
Open the web.config file and search for fully qualified names that contains 2011.1.315.40 and delete them. The same error could happen if there is reference to this version in the controls declarations in the aspx / ascx file.

Another approach is to use Assembly Binding Redirection in the web.config file as it is described in the following MSDN article: Assembly Binding Redirection, e.g.

<dependentAssembly>

<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral" />

<bindingRedirect oldVersion="1.0.0.0-2012.1.1205.40" newVersion="2012.1.1205.40" />

</dependentAssembly>

Kind regards,
