After creating a unit test app in visual studio , I get this error while running the project
"Severity Code Description Project File Line Suppression State
Warning There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

how can I fix it?
