We are getting the following error on EVERY file generated in our data access layer when we try to open it in the designer:
----

How do we correct for this problem?
Our first assumption is that we've just missed a setting somewhere, but have not yet found it.
Is it possible there is a problem in the MM.Net framework itself?

Any help much appreciated.

Thanks
