I tried to follow the documentation to add a grid to an existing client-side blazor app and it hangs upon clicking on a column to sort or using grouping:

blazor.webassembly.js:1 Uncaught (in promise) Error: System.InvalidOperationException: No generic method 'OrderBy' on type 'System.Linq.Queryable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic.

Hi Customer,  
    
Thanks for contacting Syncfusion support.  
  
We have analyzed the reported exception. We suspect that the problem is because of [Blazor] IL Linker not working properly. So we suggest you to disable the IL Linker in your application . Please add the below highlighted code in your .csproj file to overcome the problem you are facing. Please use the code below, 

 
 <PropertyGroup> 
    <TargetFramework>netstandard2.0</TargetFramework> 
    <OutputType>Exe</OutputType> 
    <LangVersion>7.3</LangVersion> 
    <RazorLangVersion>3.0</RazorLangVersion> 
    <BlazorLinkOnBuild>false</BlazorLinkOnBuild> 
  </PropertyGroup> 


Please refer the link for more information regarding this : https://github.com/mono/mono/issues/12917 

Please get back to us if you need further assistance.  
  
Regards, 
Renjith Singh Rajendran.
