Static class decorated with [Coalesce, Service] fail code generation without console error

[COsborn2]

When a static class is decorated with [Coalesce, Service] Coalesce generates invalid C# without providing error output in the Coalesce task.

Static class

namespace IntelliTect.MyApplication.Data
{
    [Coalesce]
    [Service]
    public static class UserService
    {
        public static UserInfo UserInfo(ClaimsPrincipal user)
        {
            return new UserInfo
            {
                IsLoggedIn = user.IsLoggedIn(),
                UserName = user.GetUserName(),
            };
        }
    }

    public class UserInfo
    {
        public bool IsLoggedIn { get; set; }
        public string UserName { get; set; }
    }
}

Generated Controller

namespace IntelliTect.MyApplication.Web.Api
{
    [Route("api/UserService")]
    [ServiceFilter(typeof(IApiActionFilter))]
    public partial class UserServiceController : Controller
    {
        protected IntelliTect.MyApplication.Data.UserService Service { get; }

        public UserServiceController(IntelliTect.MyApplication.Data.UserService service)
        {
            Service = service;
        }
    }
}

"Property cannot be of static class type 'IntelliTect.MyApplication.Data.UserService'"
