Make MSBuild use new Roslyn compiler in VS15 Preview
<p>I just recently delved into Roslyn compiler stuff and I'm wondering about some possibilities. I'm trying to build Roslyn compiler from Roslyn repository  using <code>features/tuples</code> branch and replace the needed DLLs in <code>VS15Preview\MSBuild\15.0\Bin</code> folder. But when I replace DLLs and build console app project I receive the following error message</p>
<blockquote>
<p>Severity  Code    Description Project File    Line    Suppression State</p>
<p>Error     The specified task executable &quot;csc.exe&quot; could not be run. Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)</p>
</blockquote>
<p>Files which I try to replace: <code>Microsoft.CodeAnalysis.dll</code>, <code>Microsoft.CodeAnalysis.Csharp.dll</code> and <code>csc.exe</code>.</p>
<p>Is it possible to build your custom Roslyn compiler for C# and replace it within VS15 Preview?</p>
