There are ready-made OpenSource graphic editors for drawings and email. schemas in .NET?

Question

User interface

Good afternoon!

The task is to make a graphical editor, like the one above.
Those. this is a set of nodes, they are connected by polylines.
It is also possible to add conditionally rectangles that are connected to nodes by connecting broken lines.

If a node/line/rectangle is moved, then the connecting lines should automatically lengthen while remaining polylines.
The option "just a connecting line from point A to point B obliquely across the half-screen" - does not work.

I have some experience, but I am tormented by the thought that I am sawing a bicycle, and someone has done something similar for a long time.

Are you aware of OpenSource projects of this kind for .NET?

I used Google for you (I didn't work with these libs myself)

If a node/line/rectangle is moved, the connecting lines should automatically lengthen while remaining polylines.

I didn’t find such a functional circuitdiagram (it has an online editor), perhaps in some separate lib and it is, if you wish, it is written - google the algorithms
