Hi,

I'm porting a Silverlight application to Asp Net Core 3.1 Web Api for back end. 

In this SL application I have many reports defined in a Visual Studio project with custom Datasource (using event NeedDatasource).

I can't mix .net core and framework assemblies and report designer in VS works only for framework 4.x projects so I can't re-use same project/dll. Is this correct, there are no ways?

If no, as I understand, I must use the Standalone Report Designer with custom assemblies for custom datasources. These assemblies should be net core or net standard assemblies, or can be also net framework assemblies?

Probably I will have also reports with only SqlDatasource.

I'm new to Standalone Designer, what are the guidelines for developing reports in my situation, for example, put everything (TRDX, Stand Alone Designer, and custom assemblies) in same folder.

How these assembly can read the connection string (from .settings file of Report Designer) ?

How to deploy these TRDX resports on server changing the connection string? About this I read this article: https://www.telerik.com/support/kb/reporting/report-designer/details/deploying-trdx-(xml-report-definition)-that-uses-external-assembly

but I think that link description and page contents doesn't match.

Sorry for long post and many questions.

Thank you very much

Andrea
