Hi I have a project that works great on my machine (and production servers).
It's a VS2010 project running C#3.5.
When letting my build server build the solution it can't resolve a couple of my third party dll's. Error message:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3268: The primary reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v3.5". To resolve this problem, either remove the reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" or retarget your application to a framework version which contains "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". [d:\Builds\3\mySolution.sln]

Everything compiles and runs great on my machine, but the build server seem to struggle.
I think the Third.Party.Assembly is written in VB.net.
Since the assembly is third party I can't remove the reference to "Microsoft.VisualBasic.Compatibility" and since I don't get any warnings on my computer could it really be that I'm running v3.5?

Any suggestions?
