title: Can't add members to SSAS role through Visual Studio
body: <p>I'm unable to add members to an SSAS role through Visual Studio. I can create a role in Visual Studio. I can add member through SSMS but cant add members through my Visual Studio project. The problem comes when I need to deploy my solution, all members added through SSMS disappear; hence, I need to solve the problem of not being able to add members through my project in Visual Studio. maybe I need to give Visual Studio some permission? </p>
  
  <p>I expect to be able to add members through my SSAS Visual Studio project and when I deploy the project again the members of the role don't get affected.</p>
  
  <p>Right now, when I click on the Add.. button nothing happens</p>
