Description

After I upgrade to the 2017.2.621 version, I am getting the following error message:

'Grid' is ambiguous because multiple kinds of members with this name exist in class 'Kendo.Mvc.UI.Fluent.WidgetFactory'.

Solutions

To solve this issue, either:

• Upgrade to a later version, or
• Install a missing NuGet package.

Upgrading the Version

Upgrade to the Kendo UI R3 2017 version or to internal builds version later than 2017.2 621.

Installing the Missing NuGet Package

Such an error occurs if the Microsoft.CodeDom.Providers.DotNetCompilerPlatform (https://www.nuget.org/packages/Microsoft.CodeDom.Providers.DotNetCompilerPlatform) NuGet package is missing from the project.

1. Install the missing package from the NuGet Package Manager in Visual Studio. As a result, the following lines are added to the web.config file of your project:

   <system.codedom>
       <compilers>
           <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
           <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\"Web\" /optionInfer+" />
       </compilers>
   </system.codedom>
   

2. Rebuild the project to locally resolve the error.

3. Deploy the project.

4. Make sure that the ..\bin\roslyn\vbc.exe file is available.
