Hi,
I maintain a VS plugin, with associated debug engine written using the MPF.
I have just implemented a disassembler module for it, but when selecting a disassembler window I get the following Exception:
An unhandled exception is about to terminate the process. Exception info:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidCastException: Unable to cast object of type 'MyCoLtd.MyPackage.CodeContext' to type 'Microsoft.VisualStudio.Debugger.Interop.IDebugCodeContext2'.
at System.StubHelpers.InterfaceMarshaler.ConvertToManaged(IntPtr pUnk, IntPtr itfMT, IntPtr classMT, Int32 flags)

at Microsoft.VisualStudio.Platform.WindowManagement.WindowFrame.OnContentShowing(View view)
at Microsoft.VisualStudio.Platform.WindowManagement.WindowManagerService.OnViewContentShowing(Object sender, ViewEventArgs args)
The C# code for the class that VS fails to cast is:
Any suggestions where the problem might be?
Thanks,
Simon.
