Description Chris Hamons 2012-10-11 16:36:29 UTC
I'm seeing this error:

Internal Compiler Error: Method not found: Class.op_Explicit CS0594

The example I'm running into has the following:

Assembly A:
   Call method that returns a Foo.

Assembly B:
   Foo is derived class of Type Bar
   Bar has an implicit constructor to type Buzz
   Buzz is defined in an assembly that doesn't load well against Mono (as opposed to the Mono friendly copy in another directory [our mistake]).

Relinking our reference to the version that has Buzz and is loadable makes it go away.

Yes, we shouldn't be adding references to assemblies that don't load under Mono, but the compiler should never ICE.

If you need a example, I can try to dig one up, but the only examples I have at hand involve assemblies I can't publicly post.

Closing as fixed as Mono 2.11 has new mechanism to check this sort of errors and will most likely fix yours as well.
