Error trying to build

[Dan Pupek]

I am trying to use VB-Doc with the 0.85 distro of Nant. I have made the changes noted in the previous post (then re-built) but I still get the following error:

System.InvalidCastException: Specified cast is not valid.

Any ideas?

Make sure to get the newest version of VB.DOC, I fixed a bug in this area in the last release. If it still doesn't work, please let me know and I will take a look at it.

I have the 0.39 distribution.

[Markus Palme]

Can you please take a look at the assembly binding log (using fuslogvw.ext) and tell me whether the resolving of CommentExtractor.dll fails?

Thanks
Markus

[Dan Pupek]

Yes it seems to fail:

The operation failed.

OK, I moved some dependencies around and everything seems to be working (I still had to apply the patch for 0.85).

VBDOCHANDLER is still reporting failures binding:
System.windows.forms
TestReference
Microsoft.VisualBasic
System

These I don't understand since three of them are in the GAC.

Any Ideas?

VB.DOC has to load depencies of assemblies you are trying to document, as a result the depencies of the assembly are binded. Looks like the version of the referenced assemblies differ from your installed framework version. Can you affirm this?

[Dan Pupek]

I am using the Test Project Provided with the Source. If it references .Net 1.0 that could be the problem.

Also, it seems like CommentExtractor references the VB.Doc Task assembly AND Vice Versa. This sort of circular referencing is usually discouraged.

[Markus Palme]

There is no circular reference - commentextractor.dll doesn't reference the task dll.

1.0 framework depencies are definitively a problem - you should try to get rid of them (if possible).
