Graph library for c#?

Hi,

Is there a well documented C# graph library that contains algorithms such as AStar, Dijskstra etc. ?

I used QuickGraph, Satsuma, but they are poorly documented and either there is no response or questions ends up in stackoverflow forum.

I know that there is a very nice python NetworkX library, but is there is something similar in c#?

Thanks,
Petras

I used it and documentation is really poor, as library is old, and there are some syntax issues when using visual studio. I simply cannot follow example files that is shown on documentation because of changesin c# between very old version and current one.
