How Did You Get This To Happen? (Steps to Reproduce)

var solutions = new string[] {
 "../solutionA.sln",
 "../solutionB.sln"
};

Task("Default")
.DoesForEach(
    solutions,
    solution => {
        NuGetRestore(solution,new NuGetRestoreSettings{
            PackagesDirectory = "../Packages/",
            ToolPath = "../.nuget/NuGet.exe"
        });
        MSBuild(solution, new MSBuildSettings() {
            Verbosity = Verbosity.Minimal
        });
    }
);

Task("Test")
.IsDependentOn("Default")
.Does(() => {
    MSTest("PATH/TO/ASSEMBLY.dll");
});

RunTarget("Default");

Output Log

PS C:\Users\build\Desktop\test\.build> .\build.ps1
Preparing to run build script...
Running build script...
PS C:\Users\build\Desktop\test\.build>

All attempts (vanilla, Verbosity, Verbosity+mono, Verbosity+Experimental) produce the error prompt

any workarounds? Does installing the .net 4.6.1 developer pack helped?

[devlead]

.NET 4.6.1 is the minimal supported .NET Runtime needed for Roslyn now, so that's why it's also needed by Cake, so no workaround avail, installing .NET runtime 4.6.1 or newer will solve it.

well, i have a colleague that has .net 4.6.2 installed and getting the same prompt. I am trying to figure out what's missing for 4.6.1 that it's asking for 4.6.1
