Upgrade Angular project with .Net 3.1 to .Net 5

Hi Team Radzen,

I'm looking for any guidelines to follow when upgrading an existing Radzen Angular application with .Net core 3.1 to .Net 5.

I have tried to use the same method I've used to upgrade from 2.0 to 3.1 by changing the serverversion to 5 and let Radzen generate the c# project.
but it shows the following in application settings:

You can try changing the serverVersion field in your app.json file to 5.

That is what I did , please see image.
After changing the serverversion to 5 , Radzen displays the dropdown with options for .Net Core 1.x and .Net Core 2.x , no other options.
The generated .Net code has the target .Net 5, so that seems to work , but the Radzen GUI displays what I have captured in the image you can see in my first post.
