Description

public struct Foo<T>
{
}

public struct Bar
{
    public static readonly Foo<Bar> Baz;
}

When loading the Bar type, a TypeLoadException is thrown.

Reproduction Steps

new Bar("Hello world!");

public struct Foo<T>
{
}

public struct Bar
{
    public static readonly Foo<Bar> Baz;
    public Bar(string message) => System.Console.WriteLine(message);
}

Expected behavior

I expect the type to load successfully, or at the very least for it to be a compile time diagnostic, rather than a runtime exception.

Actual behavior

TypeLoadException at runtime.

Regression?

I don't know any specifics, but testing on SharpLab shows that it's been broken on all .NET (Framework & Core) versions.

Known Workarounds

Moving the static field to a different type. For example:

public struct Foo<T>
{
}

public struct Bar
{
    public static class Workaround {
        public static readonly Foo<Bar> Baz;
    }
}

Alternatively, making either type a class will also workaround the issue.

Configuration

No response

Other information

This issue is an overlap of #5479 (but that has an actually recursive type in a static field), and #6924 (which is generally about unused generics).

The other issues are both closed/merged and locked to contributors. Yet the issue remains, hence I'm opening this issue.
