VS2019 does not respect default Content glob **/*.json

_This issue has been moved from [a ticket on Developer Community](https://developercommunity.visualstudio.com/content/problem/948976/vs2019-does-not-respect-default-content-glob-json.html)._

When switching to VS2019 from VS2017, we found that our ASP.NET Core project would include JSON files as build action "None" instead of "Content". According to https://github.com/dotnet/docs/issues/10272, "\**/\*.json" is a default content glob (like "**/\*.config").

This came up because Microsoft.TypeScript.MSBuild was not recognizing our tsconfig.json (it only recognizes a file of that name if it has build action "Content").

Using MSBuild directly or building with VS2017 do respect this default.
