After deploying Habitat to Azure I am getting rendering error

Question

While opening the item in the Experience editor I am getting a lot of errors like the below:

Error Rendering View: /Views/MediaFeature/LightboxVideo.cshtml: Error while rendering view: '/Views/MediaFeature/LightboxVideo.cshtml' (model: 'Sitecore.Mvc.Presentation.RenderingModel, Sitecore.Mvc').

How can I resolve this error?

Answer 1

This issue has been fixed by adding the below to the web.config:

  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs"
        type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, 
        Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.3.0, 
        Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701"/>
    </compilers>
  </system.codedom>

Yes you are right, only in if language is C#, in case if you are using VB then you can also use the below code.

<system.codedom>
    <compilers>
        <!--For C# -->
        <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
        <!--For VB -->
        <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
</system.codedom>
