I recently updated my copy of Blend to the latest Silverlight 5 preview and am now having "blendability" issues with RadChart data binding. I am running the latest version of Silverlight 5 RC and the Telerik SL controls.

This did not occur before I updated Blend. The project builds and runs fine in VS2010. This problem only occurs in Blend 4.1.10819.0.

The specific design-time error that I get is:

Method not found: 'System.Delegate System.Reflection.MethodInfo.CreateDelegate(System.Type, System.Object)'.
at System.Linq.Expressions.Compiler.LambdaCompiler.CreateDelegate()
at System.Linq.Expressions.Compiler.LambdaCompiler.Compile(LambdaExpression lambda, DebugInfoGenerator debugInfoGenerator)
at Telerik.Windows.Controls.Charting.DataBindingHelper.CreateExpressionGetter(Type itemType, String propertyName)

at Telerik.Windows.Controls.RadChart.InternalRebind()
at Telerik.Windows.Controls.RadChart.OnApplyTemplate()
at System.Windows.FrameworkElement.OnApplyTemplate(IntPtr nativeTarget)

I thought perhaps it was my code that was causing the issue, so I created a new Telerik Silverlight RadControls project from VS and copied the PieChart code from the demo, which binds the chart to a view model. 

I suspected that the problem was due to MVVM-style data binding, so I initially set the data source declaratively in XAML. No problem. It built and ran fine in Blend. 

However, when I converted it to MVVM as in the demo, I get the exception. Any ideas what's going on?

Hello Jeremy,

We haven't faced such issue with our controls in Expression Blend up to now. However you may review this forum post where a discussion for similar issue has been started. It seems that this is a Framework problem that Microsoft should deal with.
However I sent your feedback to our developers for further investigation.

Kind regards,

Hi All,
Actuall I got this error, too.
Have a look this link It says This method

MethodInfo.CreateDelegate supported in Silverlight 5,also .Net Framework 4.5.

http://msdn.microsoft.com/en-us/library/hh194376%28v=VS.95%29.aspx
My Teory: Here is the stacktrace and I'm seeing Telerik namespaces, So maybe a Telerik component developer used this MethodInfo.CreateDelegate function and people getting this error who uses  below .net framework 4.5 or Silverlight 5.


StackTrace:

Finally,
I removed installation of silverlight developer 5 from my pc. Then solved.
Maybe MethodInfo.CreateDelegate method which supported on just sl 5 & .net framework 4.5 has a bug in it.
Who knows?
