Microsoft.ReportingServices.ReportViewerControl.WebForms version 150.1404.0

Question

After installing Microsoft.ReportingServices.ReportViewerControl.WebForms version 150.1404.0 via nuget in Visual Studio 16.7.7 when I now run an existing rldc in ProcessingMode.Local I get an error:

<Error>
<Message>An error has occurred.</Message>
<ExceptionMessage>Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)</ExceptionMessage>
<ExceptionType>System.IO.FileLoadException</ExceptionType>
</Error>

How can I use this version Microsoft.ReportingServices.ReportViewerControl.WebForms version 150.1404.0 ?

Hi @Dave Anderson ,
This could be caused by several reasons, please try the methods mentioned in this thread, see if one could help: Could not load file or assembly 'Microsoft.ReportViewer.WebForms'

OR, you could follow the steps in Integrate Reporting Services Using the Report Viewer Controls - Get Started Pay attention in the registery part in step 3.

Hope this could help.

Joy

Is there anything more up to date?

The page
https://learn.microsoft.com/en-us/sql/reporting-services/application-integration/integrating-reporting-services-using-reportviewer-controls-get-started?view=sql-server-ver15

references .Net Framework 4.6 and I am using 4.8 and I am not using Windows Forms I am using Asp.Net to generate a report in an API. So step 3 is not relevant to me (not using ASPX pages).

Thanks
