Google Maps API for .NET program

I am doing the development for a program on .NET framework, in C# and part of the program is about implementing Google maps. My app receives the maps coordinates through the net from an Android device and I have to show the paps on computer screen. With my implementation, when I first open the maps, the program shows the map in the correct location, however it is not dynamic, it's just a raster image. For example when I zoom in it doesn't show a more detailed map, it just zooms in into that image which results in a zoomed in, low resolution version of the same image (like it was a raster image). It won't pan in any direction either. I just need ideas and insights about what the problem is and what the solution is (rather than do the coding for me). Thanks.
