Use Microsoft Solver Foundation in C#

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 开发者_开发百科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?

At no point did you mention that you added a reference to this library to your project, and the behavior you are describing is consistent with not having added a reference. Therefore, you also need to add a reference to this library to your project.

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".

Does "Microsoft Solver Foundation" show up when you go to Add Reference...?

If it does not perhaps you are not using the correct framework, try Project -> Properties.. -> Compile -> Advanced Compile Options... and certify you are NOT using .NET 4 Framework Client Profile (uses to be default for new projects). If it is, change it to .NET 4 Framework.

If that also fails... have you downloaded and installed the solver?

You need to add a reference to that DLL you found to your project.
