Brand new project fails to load after being converted from Nuget

[dallinbeutler]

Describe the bug I'm trying to create a brand new console project from the Ionide command-palette and convert it to Paket. When I reload the window, the project fails to load with a status of "failed to load" and an error of "Project not restored"

To Reproduce Steps to reproduce the behaviour:

1. Open VS Code in a blank directory
2. Press Ctrl + Shift + P > F#: Create New Project
3. Select New Console Application
4. Name your folder and your project. I named both "TestProj"
5. Ctrl + Shift + P > Developer: Reload Window
6. The project should reload just fine inside Ionide
7. Ctrl + Shift + P > Paket: Convert from Nuget (I also tried Paket: Install)
8. Wait for command to finish
9. Ctrl + Shift + P > Developer: Reload Window
10. Project fails to load with errors mentioned above

Expected behaviour The project should load within Ionide just fine.

Environment (please complete the following information):

• OS: Windows 10
• Ionide version: 4.14.0
• Ionide Paket version: 2.0.0
• Paket version: 5.215.0
• VSCode version: 1.46.1
• dotnet SDK version: 5.0.100-preview.4.20258.7
• mono / .Net Framework version: net5.0

Additional context My guess is something to do with the net5.0 TargetFramework being incompatible with Paket?

just tried updating paket to 5.247.2 and also 6.0.0-alpha033, still fails

I realize now this is probably a hidden backend issue related to Paket itself, considering dotnet build in the new project directory results in the error: Extracting platforms from path 'net5.0' failed, a newer Paket version might support it, otherwise please open an issue for a missing platform handler.

Should I close this issue, or wait for the solution on Paket's side to retest?
