We're targeting .NET 5 for now to make development easier while .NET 6 is not yet released. TEMPORARY REGRESSIONS --------------------- Assembly unloading is not implemented yet. As such, many Godot resources are leaked at exit. This will be re-implemented later together with assembly hot-reloading.
