I have a very strange problem. I have an Interface defined in a dll as follows:
public interface IKreator2
{
string Name { get; set; }
string Description { get; set; }
INotifyPropertyChanged Settings { get; set; }
InfiniRenderJob Job { get; set; }
UserControl UI { get; set; }
void Init();
//void OnClose();
}
If I link to this dll in my WPF app the Debugger crashes on load (Internal Error: Unhandled Exception in the debugger::HandleIPCEvent, ID=0x246). If I debug the app with "debug unmanaged code" I get the following errors:
- First-chance exception at 0x76977945 (KernelBase.dll) in InfiniRender.Host.exe: Microsoft C++ exception: EETypeLoadException at memory location 0x0029c5b8.
- First-chance exception at 0x76977945 (KernelBase.dll) in InfiniRender.Host.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.
- A first chance exception of ype 'System.TypeLoadException' occurred in InfiniRender.Host.exe
- An unhandled exception of type 'System.TypeLoadException' occurred in InfiniRender.Host.exe Additional information: Nicht abstrakte Nicht-.cctor-Methode in einer Schnittstelle.
At the Moment I have absolutly no clue what is going on. There isnt even an implentation of the interface and no class uses it. If I comment the method "Init" out, everything works as expected. Any ideas??
[EDIT] This is the MSIL for the Interface init method:
.method public hidebysig newslot virtual
instance void Init() cil managed
{
// Code size 96 (0x60)
.maxstack 3
.locals init ([0] class [mscorlib]System.Exception CS$0$0__ex)

} // end .try
catch [mscorlib]System.Exception

object)
IL_005b: rethrow
IL_005d: leave.s IL_005f
} // end handler
IL_005f: ret
} // end of method IKreator2::Init
It seems to me, that NLog is to blame? Never had any issues with NLog until today...
TypeLoadExceptioninstances are more than likely not due to the interface, but to the code that implements the interface. – Aronarondel
