应用程序服务接口（IApplicationService.cs）

using System;
using Guushuuse.SalaryPrj.Security.Dao;
using Guushuuse.SalaryPrj.Security.DomainModel;

        bool ApplicationExists(string applicationName);
        int CreateApplication(string applicationName);
        Application GetApplication(string applicationName);
    }
}

应用程序服务类（ApplicationService.cs）
