Failed to find or load the registered .Net Framework Data Provider
- fuslogvw.exe shows no binding failures when my app crashes on the test machine. - I compared the fusion logs of one that works and one that fails and there are subtle differences, but there is no way of knowing what's right or wrong. - I've compared the GAC contents of the two machines and their data components seem quite similar. - I used procmon.exe to try and find file-not-found errors, but after tediously filtering down I can't find anything obvious. - The event logs show nothing related to my problem. So this seemingly trivial error has me completely stumped. The worst and most irritating thing is that despite hours of stuffing around I can't even find a clear clue anywhere about what data provider is actually missing. I will have to write small experimental programs which incrementally introduce new dependencies to iterate towards an answer. That's an absurd waste of time. Greg
RE: Failed to find or load the registered .Net Framework Data Provider
Greg Have you looked at the Registry on both (32-bit/64-bit), under Visual Studio DataProviders? It may be a quicker comparison.

Re: Failed to find or load the registered .Net Framework Data Provider
I copied EVERY dll referenced by the project over to the test machine and it still fails. I was suspicious that the test machine it did work on had Visual Studio 2012 installed on it, so I uninstalled VS2012 and all other development tools (it's an old spare VM) and now it crashes there as well. So VS2012 is putting something on the machine that allows my app to run. I'm absolutely stumped, and I thought I knew how this stuff works. I just can't find what is the missing .Net data provider. As an aside: I just noticed that the Framework library project references are to files in these folders: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.Data.Entity.dll Didn't they used to be in the GAC? When did they move over to Program Files? Greg

Did check the fusion log to see what was being probed for?

Did check the fusion log to see what was being probed for? Ah! fuslogvw ... Good idea, I'll try it tonight when I get home -- Greg
Re: Failed to find or load the registered .Net Framework Data Provider
Hope it helps. My standard debugging technique is to now always check any and all logs I know about just in case something somewhere has recorded a little titbit of info that could be relevant.
