Project "load failed" in net5.0 devcontainer

[JordanMarr]

Describe the bug**

All projects show as "(load failed)" when run in net5.0 devcontainer -- even after a successful dotnet build.

Steps to reproduce

1. Open sln in Ionide
2. When prompted, open in remote dev container (with the "Remote - Containers" extension)
3. All projects will show as "(load failed)"
4. From terminal, cd src, dotnet build
5. All projects still show as "(load failed)" even after successful build
6. Disable Ionide and reload vscode
7. Re-enable Ionide -- only now are projects loaded properly

Expected behaviour

I would expect that projects should load properly after a successful build when in the devcontainer.

I had the same problem and this is the log appeared:

@JordanMarr one approach that worked for me was manually writing in the console: dotnet build.
