Paket with net core 3.0 fails

See original GitHub issue

Description

When running as part of dotnet build for a NET Core 3.0 solution, paket fails with an error message:

Extracting platforms from path '${targetFramework}' failed, a newer Paket version might support it, otherwise please open an issue for a missing platform handler.

Strangely, when I build from Visual Studio, all is fine. And after once building from there, dotnet build works, too. Unfortunately, I cannot apply this workaround on my build agent.

The NET Core SDK version is 3.0.100. The Paket version is 5.220.0.

@ScottHutchinson I’m trying to upgrade from netcoreapp3.0 to netcoreapp3.1. When running paket restore, I also get Extracting platforms from path 'netcoreapp3.1' failed. I can still run the project using your workaround with paket install, but restore doesn’t work. Did you manage to solve it?

Edit: I found out that my global paket tool wasn’t up to date, and once I got that upgraded I didn’t get the paket restore error anymore.

Yeah something similar here. Just want to update a small project from .NET Core 3.0 to 3.1. Build from VS works, dotnet build as well, paket restore also, paket install also. But fake build shows There was a problem while setting up the environment: -> Extracting platforms from path 'netcoreapp3.1' failed.

Using Paket version 5.247.4.
