I used the following code to get project list in vsts beta 2. But in beta 3, I can't find the 'BisProxyServices'.
BisProxyServices bps = new BisProxyServices();
ICommonStructureService iss = bps.GetTfsProxy(Tfs, typeof(ICommonStructureService)) as ICommonStructureService;
ProjectInfo[] projects = iss.ListProjects();
Is 'BisProxyServices' renamed or moved to different assembly
What is the best way to get the project list in beta 3

How can I get project list in VSTS Beta3 !!

To follow up on Brian's reply, James Manning posted a little app on his blog that will list the team projects on a server. He also explains the difference between ListProjects() and ListAllProjects().
simple command-line example: listing the team projects on a server

I don't have the exact API names in front of me right now but you use something like.
TeamFoundationServer tfs = TeamFoundationServer.GetServer(url, ...);
ICommonStructureService iss = (ICommonStructureService)tfs.GetService(typeof(ICommonStructureService);
then do what you always did.
