I have had my SF application running for a while  now and I've had no problem in the past opening up a form in Visual Studio, but for some reason today I have been getting a lot of weird problems, such as the above error, on a form which I have opened and closed without problems earlier today. Nothing has changed in the Business Object side, I am just changing the UI. "NET" is my datasource key for one of my databases.

I have also had problems with my forms that use a SharedDataTableKey.  All of a sudden I can't open these forms because the sharedDataTableKey is not defined.

Any idea's why this is happening and how to resolve?  I have tried cleaning and rebuilding my solution but it didn't help.

Thanks,

Tim
