I am trying to learn how to use the vSphere Web Services. My simple application is below. The project is made in C# with Visual Studio 2010. I am able to build the solution just fine. However, when I execute the following line of code, my CPU spikes up to about 50% for 2 minutes then completes the login process.
service = new Vim25Api.VimService();
Does anyone know why this might be happening? It makes the application extremely slow. I would think creating the VimService object would not be so CPU intensive.
Suggestions are welcome
