Exception after downgrading from 2008 vol3 to vol1
posted
I'm working on an ASP.NET app using the NetAdvantage 2008 vol 1 controls. A couple weeks ago, my machine was affected by the Conficker worm, and the It group here stripped my machine. When I reloaded the NetAdvantage controls, I mistakenly installed vol 3 instead of vol 1 and ran the upgrade utility when I had some errors.

I ended up uninstalling and installing vol 1 again and running the upgrade utility, but now I have an intermittent problem where I launch my app, and when I navigate to a page with the Infragistic controls, I get the following error:

An Exception of type 'System.IO.FileLoadException' occurred in webpo.dll but was not handled in user code. Additional information: The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) Break/Continue

I have found that if I break, stop debugging, and Rebuild the Solution, it works fine for a bunch of debugs, then comes back.

I had never received this error before.

Any idea what's causing this and how to solve it? Visual Studio 2005 VB.NET Thanks! Chris

    Hello,

    This one could be tough. It is definitely a weird error that I have not seen before, and the more infteresting thing is that it originates in "webpo.dll" -- this assembly is not part of the Infragistics suite, so I am really not sure how this relates to our products.

    Is webpo.dll a third party assembly, or an assembly that is part of your application? Is there something different in your setup from before -e.g. new OS, or installing 64-bit OS instead of 32? Are you using any sort of remote debugging that may require addition permissions?
