Hi Chris,

Hmm, tried the following code and it works fine:

static void Main(string[] args)
{
        var client = GroupShareClient.AuthenticateClient("username",
                "password",
                new Uri("http://your_address_here"),
                GroupShareClient.AllScopes);

        Sdl.Community.GroupShareKit.Clients.ProjectsRequest req = new Sdl.Community.GroupShareKit.Clients.ProjectsRequest("/", true);
        var projectsCount = client.Result.Project.GetAllProjectsForOrganization(req).Result.Count;

        Console.WriteLine(projectsCount);

        Console.ReadLine();
}

Probably something silly missing on my side, but doesn't work for me.  My original code was in a windows forms app.  Created a trivial console app like your code and still no projects returned:

    class Program
    {
        static void Main(string[] args)
        {
            var client = GroupShareClient.AuthenticateClient(@"me",
                    "mypassword",
                    new Uri("nygroupshare01.corp.bloomberg.com"),
                    GroupShareClient.AllScopes);

            Sdl.Community.GroupShareKit.Clients.ProjectsRequest req = new Sdl.Community.GroupShareKit.Clients.ProjectsRequest("/Test", true);
            var projectsCount = client.Result.Project.GetAllProjectsForOrganization(req).Result.Count;

            Console.WriteLine(projectsCount);

            Console.ReadLine();
        }
    }

I tried as "sa" and as my login.  Confirmed my account has full privilege on the Test organization. Is there some other level of permissioning that should apply?

 Here is the list of projects visible from Trados Studio:

Switched code to

            IReadOnlyList<Sdl.Community.GroupShareKit.Models.Response.Project> allProjects;
            allProjects = client.Result.Project.GetAllProjectsForOrganization(req).Result;

Function call returns successfully,no exceptions thrown,  but allProjects.Count = 0

            allProjects = client.Result.Project.GetAllProjectsForOrganization(req).Result;

 Function call returns successfully, no exceptions thrown.  allProjects is a valid object, but allProjects.Count returns 0

GroupShareKit is async library so you should use the async/await keywords. You can avoid them by using the Result property. You can also look at the unit tests code to see how the librarys was used:
