Deep Learning C# - Solution to find object coordinates in image

I have images of object and images contain that object.

With another image(contain object), i need to know object coordinates(x,y).

I want to train a neural network with library to find it.

Is it possible with only 5 image of object and 5 image contain that object ?

If it is possible, please give me a solution to find it and example with c# if you free.

Thanks !
