Hi,

I think I'm slowly going nuts. When I start our application on my home computer I get the following exception:

No upgrade handler is found for assembly 'DataObjectsFirstLook', version '1.0.0.0'.

  • There's no reference in the Solution anywhere to this Assembly.
  • There's no Assembly relying on this Assembly.
  • There's no App.Config containing this Assembly Name.
  • I've scanned the entire disk for any reference to this Assembly, there are none.
  • I've looked with Process Monitor. Nothing.
  • Scanned the Registry. Nothing.
  • Looked with Reflector. Nothing.
  • Tried to understand the .targets files in the Common directory. As far as I can judge, there's no path leading to this specific Assembly.

The DataObjectsFirstLook was our first Project to take a firm look at DataObjects.Net 4.0. We've used this project since then only for testing purposes. It is not used in the main project.

The funny thing is that when I run the application on the computer at our office, it starts without any problem! So it must be something local. After about 4 hours of debugging, scanning, searching and total frustration. I've given up. I've got no clue why this exception is thrown.

Hi,

Solved it. My own mistake again. Simply renaming a DB, in SQL Server, is not possible with DO4 (I should have realized that, but didn't). The 'DataObjectsFirstLook' name is in the MetaData in the DB. That's where the exception came from. The only remark I could make is that the message in the Exception could have been a bit clearer. Still learning how to use DO4 here, sorry.

I'm at least happy that the error is explainable. Says something positive about the quality.
