I am having the same error, and have attached a debugger to VS (2008) to catch the exception, but no useful information came of that.
The exception (without any InnerException) is:
Microsoft.VisualStudio.Data.DataProviderException occurred
Message="An unexpected error occurred in the .NET Framework Data Provider for SQLite. Please contact the provider vendor to resolve this problem."
Source="Microsoft.VisualStudio.Data.Compatibility"
StackTrace:
at Microsoft.VisualStudio.Data.Compatibility.NewProviderObjectFactory.Microsoft.VisualStudio.Data.Core.IVsDataSiteableObject<Microsoft.VisualStudio.Data.Core.IVsDataProvider>.set_Site(IVsDataProvider value)
InnerException:
When I try to add a data source (as done in the video on the homepage of this site), I do not get a prompt with multiple fields. I get a prompt to set the ConnectionString property (see image). When I click Ok, with or without specifying a connection string, I get the exception.
My co-worker is not having this problem, and I have re-installed VS08 to no avail. Any ideas?
