title: Core ASP.NET Project Azure Build Pipeline
body: <p>I have a simple solution that have two projects in it and I want it go through the azure build pipeline. One project is pure class files that will get build a DLL but that code is not the GIT repo in the same folder. And the other project is ASP.NET project and I have configured that in the pipeline. When I am trying to build the project it is giving me an error as below: </p>
  
  <blockquote>
    <p>MSBUILD : error MSB1011: Specify which project or solution file to use
    because this folder contains more than one project or solution file.
    [error]Cmd.exe exited with code '1'.</p>
