In the meantime, I will add some more try/catches and more descriptive error messages to the GetBusinessObject() method to see if we can't track down where the problem is coming from.

Thanks for your response and the effort that you have gone through in order to assist me.

I re-ran my brief tests (open the updated and installed C# sample projects in VS, run, go to the
Customers Grid, click Edit then Cancel) before updating the assemblies to
confirm that the problem was indeed still there, and obtained the
identical results - Business Object not found on page.

I then updated the assemblies and registered them using gacutil.   I now
cannot get any version of the C# web samples to fail (other than from
InvalidCastExceptions) which is great for me, but doesn't assist either
you or me in knowing what was amiss.

The only conclusion I can draw from here is that the process of
registering the assemblies has resolved whatever the issue was.   You will
most likely have more insight into what that may mean than I do.

I will now create a small business object library based on our database schema, and see how it
goes.

I hope you are all feeling better.

Thanks again.
