Description

When converting an statement body to an expression body, the IDisposable that gets returned is marked as undisposed, but it should not because it is a factory method.

Source Code

namespace SomeNamespace
{
    class SomeClass
    {
        public IDisposable Bla() => new MemoryStream();
    }

}
