Using Git Submodule to share Nuget.Config

[PBarnard]

We have a large number of netcore microservices and would like to share the same nuget.config content for each. We thought that git submodules would help here and updated the nuget.config accordingly.

The content of the nuget.config is now "modules/our shared stuff repo name/Nuget.Config".

Doing this unfortunately breaks Nuget in VS2019 as it complains about the config file not being valid xml.

Other tooling works ok in VS2019/2022, like the ".editorconfig" being shared the same way for example.

Is this not something that Nuget is capable of?

Oh, forgot to mention that devs running Rider on their Macs or Windows don't have the problem, the submodule works ok for them.
