Please verify that you have installed the following nuget packages.

For Winforms : https://www.nuget.org/packages/Microsoft.ReportingServices.ReportViewerControl.Winforms/140.340.80

For ASP.NET : https://www.nuget.org/packages/Microsoft.ReportingServices.ReportViewerControl.WebForms/140.340.80/

You might also need to install the Report Designer :

If it does not work, click "continue" in Visual Studio debugger when you get the exception and go see on the Web page what are the error details.
