Source Generator fails for types in a "OneOf" namespace

[StefanLochauMF]

When defining a type inheriting a OneOfBase<T,...> with the [GenerateOneOf] attribute inside a namespace that contains "OneOf" as a segment, the generator fails.

User code:

namespace MyLibrary.OneOf.Extensions;

[GenerateOneOf]
public sealed partial class OneOf1 : OneOfBase<object>;

Generates:

// <auto-generated />
#pragma warning disable 1591

namespace MyLibrary.OneOf.Extensions
{
    partial class OneOf1
    {
        public OneOf1(OneOf.OneOf<global::MyLibrary.OneOf.Extensions.A> _) : base(_) { }

        public static implicit operator OneOf1(global::MyLibrary.OneOf.Extensions.A _) => new OneOf1(_);
        public static explicit operator global::MyLibrary.OneOf.Extensions.A(OneOf1 _) => _.AsT0;
    }
}

The issue lies with the constructor argument, where the compiler tries to resolve OneOf.OneOf<...> as MyLibrary.OneOf.OneOf<..>.

This could be fixed by adding a global:: in

OneOf/OneOf.SourceGenerator/OneOfGenerator.cs

Line 87 in 6e02dbe

public {classSymbol.Name}(OneOf.OneOf<{oneOfGenericPart}> _) : base(_) {{ }}

to make it

public {classSymbol.Name}(global::OneOf.OneOf<{oneOfGenericPart}> _) : base(_) {{ }}
