 error CS0012: The type 'DataSourceRequest' is defined in an assembly that is not referenced. You must add a reference to assembly 'Telerik.DataSource, Version=2.1.3.0, Culture=neutral, PublicKeyToken=29ac1a93ec063d92'.

[RESOLVED] Error CS0012: The type 'DataSourceRequest' is defined in an assembly that is not referenced. You must add a reference to assembly Telerik.DataSource, Version=2.1.3.0 in UI for Blazor | Telerik Forums

I know it was discussed at this URL.
But when I build the Dockerfile, the error is still there.

When will this error be fixed?

Package : Telerik.UI.Blazor(4.1.0)

Hello Yeongseok,

I confirm that the problem is already fixed. You need to clear the NuGet cache in all environment(s), which restore and build the app.
