Receiving CS0234: The type or namespace name 'VisualStudio' does not exist in the namespace 'Microsoft' using MSBuild.exe

I am trying to build a dotnet solution using the below command but getting error: CS0234 and CS0246

Command:

>"C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" Test.1.8.131.sln

error CS0234: The type or namespace name 'VisualStudio' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

error CS0246: The type or namespace name 'TestClass' could not be found (are you missing a using directive or an assembly reference?)

error CS0246: The type or namespace name 'TestInitialize' could not be found (are you missing a using directive or an assembly reference?)

error CS0246: The type or namespace name 'TestMethod' could not be found (are you missing a using directive or an assembly reference?)

Can anyone please tell if I am missing something.

All these are failing while trying to build the test Projects.
