title: Windows phone 8.1 RT - ViewModel Unit Test - Mocking Framework
body: <p>I have Windows phone 8.1 RT app. I want to write ViewModel Unit test.  So I have created Windows phone Unit test project.</p>
  
  <p>I can't able install any Mocking framework like NSubstitute, Moq..</p>
  
  <p>If i create General Unit test project, I can able to install the NSubstitute, but i couldn't refer the Windows phone 8.1 project because TargetFramework of Unit Test project is .Net framework 4.5.2.</p>
  
  <p>Please help me to test my ViewModel using Mocking framework.</p>
  
  <p>Thank you,</p>
