❔ Swagger shows unwanted schemas when with minimal api

Hey. If I have an endpoint like this:

app.MapGet("foo", () => Foo.Bar).Produces(StatusCodes.Status200OK);

app.MapGet("foo", () => Foo.Bar).Produces(StatusCodes.Status200OK);

Where the method Foo.Bar looks like:

public static class Foo
{
    public static IResult Bar()
    {
        return Results.Ok("foo-bar");
    }
}

public static class Foo
{
    public static IResult Bar()
    {
        return Results.Ok("foo-bar");
    }
}

My swagger output includes a bunch of schemas. If I simply do the endpoint like this instead, they don't appear:

// adding () after Bar makes the schema work as expected
app.MapGet("foo", () => Foo.Bar()).Produces(StatusCodes.Status200OK);

// adding () after Bar makes the schema work as expected
app.MapGet("foo", () => Foo.Bar()).Produces(StatusCodes.Status200OK);

This is obviously not a problem with an endpoint like this, but as soon as the endpoint starts taking in stuff from DI it becomes a problem

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
