We are seeing an intermittent bug in the Visual Studio tooling for BizTalk Server 2010 in which we are unable to build BTS projects. An error message is repeatedly shown saying that the system "Could not find file ‘Microsoft.BizTalk.TOM.resources". I suspect that this may be casued by searching for a non-existant satellite assembly for Microsoft.BizTalk.TOM.dll, but this is a guess. The error may be thrown in System.Reflector.RuntimeAssembly.InternalGetSatelliteAssembly which is at the end of several call chains leading back to BizTalk development tools.I'm using a straightforward build of Biztalk Server 2010 RTM (not in list below, so I chose 'Beta') with VS 2010 Premium on Windows Server 2008 R2. The machine locale is United Kingdom, which may be relevant.
