Hi,

I'm trying to run a solution on Azure. I'm using the latest DO RC2 release dlls. As soon as I add the Xtensive assemblies as references to the Services role project, upon debugging and navigating to http://127.0.0.1:8091/MyService.svc, I get the below exception.

I'm guessing it has something to do with the fact that I'm running Windows 7 x64 and the Oracle dll isn't present in x64 format (note the bad image format message in the error)...but my question is why is simply referencing the Xtensive dlls causing my services role to try to load the Oracle dll(s)? I'm not even referencing the Oracle specific Xtensive dlls. I've created an x86 build configuration but then I get a message from Visual Studio telling me that Azure tools only supports AnyCPU and x64.

Thanks in advance for your assistance.

Ok, nevermind, I figured it out. It was caused by referencing Xtensive.Storage.All, which seems to include all your storage providers...

Is there any documentation on what dlls I should be referencing for my solution? I've been just guessing/copying from some of your sample projects. There are a bunch of dlls and it's not clear to me what's necessary and what's not...especialling with those Indexing and Modeling dlls...

A list of each dll, what it's responsible for and whether or not it's required would be really helpful.

Thank you.
