Hi, I have an project that use a dll. What is the right way to export the project together with my custom dll? Here the error:

    Unhandled Exception:
    System.TypeInitializationException: The type initializer for 'Sys' threw an exception. ---> System.DllNotFoundException: System.Native assembly:<unknown assembly> type:<unknown type> member:(null)

EDIT: The point where the error seems show up is this section that is working in source project:

_mousePosition = GetViewport().GetMousePosition();
 ((Label)GetNode("MousePositionLabel")).Text = _mousePosition.ToString();
Label)GetNode("MousePositionLabel")).SetGlobalPosition(new Vector2(_mousePosition.x - 20, _mousePosition.y - 20));

this is my csproj

<Project Sdk="Godot.NET.Sdk/3.3.0">

    <TargetFramework>net472</TargetFramework>

GodotUtilities.dllis my custom dll

Thank you.

Is Utils a folder in your Godot project? If so, I think you can just use Utils\Utils\bin\Debug\etc to get the path, at least based on a project I've worked on that uses a custom .dll file.

I investigate a bit more and: I reach GodotUtils.dll already because I have in shell logs that are in dll:

<snip>

for example: the (448458) 16:54:55.980 :DEBUG Setup[Void _Ready()] are format logs that are made in my dll

But I have other errors (like the one posted here) that I don't have when I run the original project in godot editor.

I think the error line in the stak I posted: at Godot.Vector2.ToString () [0x00001] in <bde67218aec4446f97aac988b2b6561a>:0

is referred to this conversion _mousePosition.ToString() that make no sense. Why Tostring() fail?

edit: the scene where the error came out is a scene that will be freed using queuefree.. Its something related? edit2: I commented the section in error and I have another error further on:

Seems same kind of error:

at Godot.Vector2.ToString () [0x00001] in <bde67218aec4446f97aac988b2b6561a>:0

this time the error is related to Log.Print(Log.DEBUG, GetUsedRect());

In effect in stack trace I have these two rows:

      at Godot.Vector2.ToString () [0x00001] in <bde67218aec4446f97aac988b2b6561a>:0 
      at Godot.Rect2.ToString () [0x00001] in <bde67218aec4446f97aac988b2b6561a>:0

Update: I investigate more.... and... I had dll and project compiled using two different godot version. :astonished: Once I used the sabe version for both dll and project the

 Unhandled Exception:
 System.TypeInitializationException: The type initializer for 'Sys' threw an exception.

Disappeared.

Updated git issue too.

Thanks @TwistedTwigleg :)
