TypeLoadException

Hi,

I created a web project in vs. 2005. Later moved to vs. 2008 and it converted it. Also changed it from .net 2.0 to 3.5.

The Solution contains the main webforms project, a bol base project, and a bol project. The solution compiles fine and I can publish and run it to my XP testing server.

But when I publish it to the production windows 2003 server then I get the error below. Any suggestions on what gives?

Thanks

Thanks for the response.

I had compiled the app in the latest beta from your site. So I decided to first reinstall the app to latest release version, recompiled the business objects and try again. The error then dissapeared. I guess when I have time I'll try re-installing the beta, rebind/recompile the BO's and see what happens then.

I'll let you know what happens.

Thanks,

Marcel

Howdy!

It looks like you need to either update your StrataFrame Business .dll on the web server (this is the most likely since it works on your XP machine), and/or rebuild your business project (wherever your business objects are stored). We changed the way this works in the latest build, and it looks as though the version of your business objects and the StrataFrame Business .dll version are out of sync.

Check both of those and let us know :).
