Greetings:
Forgive me if this has already been solved; but I cannot find it anywhere on the forum.
I recently upgraded from RadControls AJAX Q1 2008 to Q2 2008.
All of my development to that point works OK, however, the following error that is appearing at design time:
Warning 1 Generation of designer file failed: Unable to create type 'telerik:RadGrid'. Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
This error is shown anytime there is a Telerik control being added to a page.
Looking in the web.config there is no reference to anything with that version, so I don't know who is referencing it. The following redirection is in the web.config...
<
runtime>
<
assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<
dependentAssembly>
<
assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
<
bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</
dependentAssembly>
<
dependentAssembly>
<
assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
<
bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</
dependentAssembly>
</
assemblyBinding>
</
runtime>
Without the above redirection, the runtime will fail. Still nothing seems to be helping with the design time issue.
Dot.NET 3.5 is installed.
Once this error is shown, then the code behind page cannot see any new tags being added to the aspx page.
I have tried for 3 days to find the answer on this site and others; but now I must surrender and post this request for help.
Please advise if you have some idea how to resolve this.
Thanks,
Robb Murdock
