Paket Simplify with Framework set to auto-detect fails with 'the framework restriction could not be determined'

[baronfel]

Description

Using the framework: auto-detect ability of paket.dependencies prevents the user from running paket simplify. The following error is produced:

C:\code\opus\Api.Tenant [master ≡ +2 ~0 -0 !]> .paket/paket simplify --verbose
Paket version 3.1.3.0

Paket failed with:

Repro steps

Use framework: auto-detect in your paket.dependencies, then try to simplify.

Expected behavior

The framework to use is inferred from the projects in the solution pre-simplify.

Actual behavior

The exception above is presented.

Known workarounds

Specify the exact framework in the paket.dependencies file.

I was going to take a look at this one after work today.

[baronfel]

Ok, got it to work. PR incoming. This was a little tricky/disruptive, though.

I still have issues with the framework: auto-detect -- running paket 3.19.3.0. Same response,
The framework restriction could not be determined.

But according to this it should be resolved?
