C# Streaming screen over Network

I'm looking for a framework/toolkit/component or a way, to stream the screen or a specific window/control (Wpf) over the Network. Here are some specifications:

stream the screen or a specific window/control (Wpf) over local network
consistently good stream
it should be performant
only the video, no audio etc. needed
no height fps needed
no specification, how to play the video (Browser, vlc, ...)
the cursor should not flicker (mostly result of the screenshots)
easy to handle
It should not cost 4000$ for streaming a screen ...

There are a lot of similar questions like this one, but they are nearly 10 years old. Most of them are answered with: Take screenshots, but this let flicker the cursor and costs cpu and I think there are better ways today.

What's already done

I have already tested a self-implemented variant with screenshots described here with an mjpeg over http.
I have also tried a variant with vlc.dotnet, but it seems, that it takes also screenshots and isn't very performant.
I have also searched for payed versions like FlashBack and zdsoft.
I have also a looked on NVIDIAs ShadowPlay and Shield Stream.

The question

Is there any framework/toolkit/component that streams/shares a desktop or a part of it performantly over a local Network? Is there any other modern way to do that? It would be like Microsoft Teams Desktop sharing.

I'm new to this, so I hope you can help me to get this.

Solution

I ended up it with a VNC Nuget like @bradbury9 has proposed. It has best performance.
