SpecsFor MVC with .NET 4.6

// SpecsFor MVC doesn't seem to pick up the correct MSBUILD to use
// when it tries to compile your web app to host in IIS express.
// If you add a reference in your Test project to "Microsoft.Build.Utilities.v12.0"
// you can then use the "ToolLocationHelper" to get the MSBUILD.exe for a VS version

string msBuild = ToolLocationHelper.GetPathToBuildToolsFile("msbuild.exe", "14.0"); // 14.0 hard coded for VS2015
            
var config = new SpecsForMvcConfig();
config.UseIISExpress()
    .With(webProjectDirectory, solutionDirectory)
    .ApplyWebConfigTransformForConfig("Acceptance")
    .UseMSBuildExecutableAt(msBuild); // <-- This is the important part
