Compiling website projects with Roslyn

In NuGet, add Microsoft.CodeDom.Providers.DotNetCompilerPlatform.

When you add this DLL, the following is automatically added to the Web. config

 <system.codedom>    <compilers>      <compilerlanguage= "C#;cs;csharp"extension= ". cs"type= "Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, version=1.0.8.0, Culture=neutral, publickeytoken= 31bf3856ad364e35 "WarningLevel= "4"compileroptions= "/langversion:default/nowarn:1659;1699;1701" />      <compilerlanguage= "Vb;vbs;visualbasic;vbscript"extension= ". vb"type= "Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, version=1.0.8.0, Culture=neutral, publickeytoken= 31bf3856ad364e35 "WarningLevel= "4"compileroptions= "/langversion:default/nowarn:41008/define:_mytype=\&quot; web\&quot; /optioninfer+ " />    </compilers>  </system.codedom>

The DLL itself also relies on Microsoft.Net.Compilers (>= 2.4.0).
