An exception is thrown after plugin update

[Richmet706]

Hi. I ran the install for the latest release successfully. When I try to run the scene I am getting an error. Did I mess up something with the install?

LogUnrealCLR: Error: UnrealCLR::Module::Exception: Loading of assemblies failed

Have you recompiled your project with an updated framework?

Also, the compilation of assemblies during installation could be done incorrectly. Try to re-run installation if the recompilation of your .NET project doesn't help.

Thank you Stanislav. I got it working.

Glad to hear.

I have a similar error:

Cannot bind to the target method because its signature is not compatible with that of the delegate type.
   at System.Delegate.BindToMethodInfo(Object target, IRuntimeMethodInfo method, RuntimeType methodType, DelegateBindingFlags flags)
   at System.Delegate.CreateDelegateInternal(RuntimeType rtType, RuntimeMethodInfo rtMethod, Object firstArgument, DelegateBindingFlags flags)
   at System.Reflection.RuntimeMethodInfo.CreateDelegateInternal(Type delegateType, Object firstArgument, DelegateBindingFlags bindingFlags)
   at System.Reflection.RuntimeMethodInfo.CreateDelegate(Type delegateType)
   at UnrealEngine.Framework.Shared.<>c__DisplayClass16_0.<GetFunctionPointer>b__0()
   at UnrealEngine.Framework.Shared.Load(IntPtr* events, IntPtr functions, Assembly pluginAssembly)

I put them into the try-catch block so I could continue using the framework.
But anyway why it is trying to create delegates for every method of every type in all assemblies? Is it necessary?

Methods on which is it crashing (I am not sure right now which one of "IsUnmanaged" methods):

public static int SizeOf<T>() where T : struct
public static bool IsUnmanaged<T>()
public static bool IsUnmanaged(this Type t)

I have a similar error

How to reproduce it? I pushed a minor change to the master now, give it a try.

Delegates are created only for specific types of functions.

Ok, I will try it later :)
