I'm trying to use Microsoft Solver Foundation in my C# application in VS2010 Ultimate. I've installed MSF (64 bit version) and as far as I understand I should be able to use the services after declaring:
using Microsoft.SolverFoundation;
However, I get the error "The type or namespace name 'SolverFoundation' does not exist in the namespace 'Microsoft'".
I see that there's Microsoft.Solver.Foundation.dll located in C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0
Initially I thought the 64 bit version might be the problem so I uninstalled and switched to the 32 bit version. But no success either.
How can I integrate MSF into my C# application?
I've already tried adding the references before but it wouldn't work. Now I've noticed something in the warnings (which I probably didn't see before):
"The referenced assembly "Microsoft.Solver.Foundation, Version=3.0.1.10599, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" could not be resolved because it has a dependency on "System.Web, Version=4.0.0.0, Culture=neutral which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project."
I fixed this by setting Application Properties -> Application -> Target Framework from ".Net Framework 4 Client Profile" to ".Net Framework 4".
