When I open a project in Visual Studio running with the .NET Standard branch of Rezoom.SQL I get the following error:

The type provider 'Rezoom.SQL.Provider.Provider' reported an error: The type initializer for '<StartupCode$Rezoom-SQL-Compiler>.$Rezoom.SQL.Compiler.Config' threw an exception.
Seems like a VS specific problem: Neither dotnet CLI nor VS Code have a problem with the project.
PS: I'm aware of the fact that this project seems to be a bit abandoned (no offense to you @rkosafo) but I hope a running .NET Standard (#15) version of this library will bring a lot more interest in this project.
