I can't create a report with an object datasource in Visual studio 2019

Question

I am trying to create a simple report in my vs2019 with a class as the data model

1. I have a public class named 'persona'
2. I have a new wpf applicacion (.net 5)
3. I've create a new report (RDLC file)
4. I try to use a class as a data template to design the report When I try to reference the class as the data source object, the class is not visible for the datasourtce wizard as you can see in the image below

If put that class in a diferent project, a class library project, I got a different error, as you can see in the images below

And whe I press the Finish button I got this new erro:

There is no clue about what to do,... does anyone have any idea ? What Am I doing wrong?

Answer 1

I have same problem. Try to use netstandard2.0 for model library, it works for me (vs2019 netcoreapp3.1)
