Method not found: 'System.Delegate System.Reflection.MethodInfo.CreateDelegate(System.Type, System.Object)'.

Hi Telerik Team,

I upgraded my Silverlight Runtime Developer ver.4 to 5 (except SDK & toolkit) 
& Telerik RadDataPager Controls is throwing exception.

Currently I have Telerik Build 2011.3.1116.1040

Is That mean, only Telerik Data Controls are not working with Silverlight 5?

Can you please tell me , How to fix this problem?

[Shrikant]

Finally Above error solved after performing some few installation steps :

1. Installed Silverlight 5 Tools for Visual Studio 2010 SP1 (SDK) (http://www.silverlight.net/downloads)
2. Installed Silverlight 5 Rumtime Developer
3. & Installed New Build of Telerik Silverlight 5 Controls ( File Ver. 2012.1.215.1050 )

[Shrikant]

Now , This is very bad

Above error still occur with SL 4, so that means If you are running with SL4 projects
you will need to set TargetFramework to 5 or Create New Projects with SL 5.

Telerik Team , Can you please update anything here?
When this will be get done?

[OmarOrnelas]

I am having the same problem with our existing SL 4 projects (that we are not ready to move up to 5 just yet) I would also like a solution for this. I had to do a system restore at one point on my system to be able to work on my SL 4 projects.

Same thing here any news ?

Hi,

We are having some problems reproducing this behavior. Could you please try if this happens with a new SL4 project that you create or just with an old project after the upgrade to SL5 runtime?

Currently it's an old SL project.

Hi,

Indeed there was such a problem with the designer. It was fixed and if you use the Q3 2011 SP binaries, you will not get this error any more.

Please check and let me know if you still have the problem with the version '2011.3.1220.1040'?


All the best,

Hello,

 I have used the attached project for testing. Could you please change it so that I can see where my mistake is?

All the best,

I've got the same problem with my projects.

Probably the easiest way to repro this is to open "DomainDataSource" demo from  "RadControls for Silverlight Q1 2011".

[Anatoly Chekh]

Hello.

We have error like this.
Can you explaine, what path "c:\TB\101\WPF_Scrum\Release_SL\Sources\Development\..." does mean? We dont have any files into this folder.
Why you try to get anything from this path?

Thanks, Anatoly.

[Ray White]

I get this same error when I attempt to open Example.xaml in Sparkline.Silverlight\LargeData in the ExamplesCS_SL solution.  (This is the Telerik example program, download on 5/1/2012.)
