Attempting to compile a model written in the Delphi Prism language fails in Visual Studio 2010 with the following error:

Error   1   (PS0099) Unhandled exception (, 64 bit, CLR 4.0, Release):
    Error while loading the type "Xtensive.Core.Weaver.PlugIn, Xtensive.Core.Weaver": 
    Could not load type 'PostSharp.AspectWeaver.PlugIn' from assembly
   'PostSharp.Sdk, Version=, Culture=neutral, PublicKeyToken=b13fd38b8f9c99d7'.
===== Start of PostSharp Assembly Binder ===========================

Since it seems to be a configuration issue with PostSharp when using something other than C# or VB.NET, I was curious if this did not have an obvious solution.

Incidentally I find Delphi Prism's "built in" language support for AOP to be quite compelling (see this page). No, I don't expect you to dump PostSharp and re-implement DO.NET in Delphi Prism.

I'd be happy just to be able to use F# and/or Delphi Prism in VS.NET with DO.NET... ;)

Hmm, have you tried to enable Fusion log and see what's wrong with assembly loading?

I have not actually. Will do, thanks for the idea.

One Answer:

PostSharp currently doesn't officially support Delphi - that's the main reason.

For now we aren't ready to dedicate some forces on reproduction of this issue. But we're ready to help you to enable it for Delphi by advices -- i.e. we're ready to answer on any precise question like this.

I would like to understand how PostSharp "injects" itself into targets, that might help me figure out what changes need to be made to make it work. I may have the same problem with F# targets as well once I get past the "dual interface implementation" problem with the next build of DO.NET, so understanding this is probably useful for all language targets not (yet) officially supported by PostSharp.
