TypeLoadException inside a dynamically loaded assembly

[Pierre-Alain Vigeant]

Hi,

I'm getting a TypeLoadException inside an object that is located in a DLL
that is dynamically loaded.

I have this main program "main.exe" that dynamically load "main.dll" using

o = AppDomain.CurrentDomain.CreateInstanceFromAndUnwra p(mainDLLPath,
"FullyQualifiedNamespace.Main.EntryPoint")
o.StartMain(Nothing, Nothing)

At this point, a new instance of EntryPoint is created and the StartMain
method is invoked. Then the EntryPoint load a form which in turn call a
WebService that return a dataset. When the WebMethod return, I get a
TypeLoadException.

Message: Could not load type
FullyQualifiedNamespace.Main.ws_GeneralService.dsT askList from assembly MAIN,
Version=1.5.0.0, Culture=neutral, PublicKeyToken=null.

The only things I can analyze from here is that it try to look for an object
inside the main.exe and not inside main.dll. I know that from the version
1.5.0.0 which refer to the main.exe version.

Someone know why this problem is happening? If you have any idea, suggestion
et online reference, please inform me.

Thank you.
