I have a Foo.csproj with a class in it: Utils.cs. In my Foo.Tests.csproj, I have a UtilsTest.cs. In Utils.cs, I have a global alias:

global using ProfileDataCollection =
    System.Collections.Generic.IDictionary<string, TrashLib.Sonarr.ReleaseProfile.ProfileData>;

I was expecting ProfileDataCollection to now be usable everywhere, sort of like C++ typedefs. However, I'm not able to resolve this symbol from UtilsTest.cs. Do global usings not cross project-dependency boundaries?

I'm using .NET 6 + C# 10 with <ImplicitUsings> set to enable.
