Radzen does not run the project

I was running this project every day but today it is not working.

"Target framework 'net5.0' is out of support and will not receive security updates in the future. Please see: .NET and .NET Core official support policy for more information about the support policy."

This is not related to Radzen - most probably you cannot run your project using dotnet run as well. The important error is duplicate PackageReference - check your csproj.

I can run the project with visual studio.

Can you run it using dotnet run? This is what Radzen is using.
