Region selecting GUI library
I am developing the image recognition software in C# and Windows Forms.
The software has a function that let user edit the area/region of
input picture with mouse drag such like rectangle tool in mspaint.exe.
I know I can handle mouse down/up events then draw rectangle on the picture.
But I want to use some library which make interactive GUI coding simple.

Does anyone know the library or toolkit which can include my software.
