Problems with .Net Native compiling

[Gabor]

Our current project requires Telerik controls for displaying statistics (mainly using the Charts and Gauges).

 

For this, initially, I used the Win8.1 Universal SDK, but it had a huge issue - the Telerik.Core.BindingExpressionHelper uses reflection, and does not define itself as Dynamic, for the .Net Native compiler.

 So I installed and selected the UWP SDK, which is supposed to work just fine. However I get the same exception:

Exception thrown: 'System.Reflection.MissingRuntimeArtifactException' in System.Private.Reflection.Core.dll

Additional information: MakeGenericMethod_NoMetadata, Telerik.Core.BindingExpressionHelper.ToUntypedFunc<TestApp.Models.Data,System.Double>(System.Func<TestApp.Models.Data,System.Double>). For more information, visit http://go.microsoft.com/fwlink/?LinkId=623485

 

 

In theory if Telerik released a truly release build of their libraries, it should already be .Net Native compiled and checked for such errors.

Telerik Support directed us here:

http://docs.telerik.com/windows-universal/common/troubleshooting/appthrowsexceptioninreleasemode

 

However, even after adding the proper entries (see below), it fails with the same exception. I also made a note that the "TestApp.Models.Data" class mentioned does NOT exist in our project.

Okay, the issue was that the documentation is missing one key point - defining not WHAT to work on, but HOW.

 For it to work properly, add the Dynamic tag to each MethodInstantiate, with the Required value:

 

<Type Name="Telerik.Core.BindingExpressionHelper">
    <MethodInstantiation Name="ToUntypedFunc" Arguments="TestApp.Models.Data,System.Double" Dynamic="Required"/>
</Type>
