Adding a EF Core 5 context in Linqpad 6 throws Could not load file or assembly 'System.Runtime' error

Question

I've taken a EF Core 3.1 project and converted it to EF Core 5. The DLL builds and I can access the data as expected from my application but when I try and access the context from Linqpad 6 I get:

Could not load file or assembly 'System.Runtime, Version=5.0.0.0. The system could not find the file specified.'

Any suggestions on what might be causing this only in LinqPad 6?

Answer 1

This is fixed in the test LINQPad beta.
