动软.Net代码生成器生成Model插件,适用于Silverlight创建NotifyPropertyChange类

Silverlight创建继承INotifyPropertyChanged接口的类会产生大量如下代码:

/// <summary>
        /// 说明
        /// </summary>
        public string description
        {
            get { return _description; }
            set
            {
                if (_description != value)
                {
                    _description = value;
                    NotifyPropertyChanged("description");
                }
            }
        }

虽然VS的CodeSnippets已经能够简化大量代码输入
但用惯了Codematic从数据库直接生成Model类,感觉CodeSnippets还是效率太低
于是修改了Codematic的BuilderModel组件,使生成Model代码支持Silverlight的需求
感谢李天平大哥对Codematic的开源:)

 

插件下载地址:https://files.cnblogs.com/zhlei616/BuilderModelSilverlight.rar

下载后将解压包里的LTP.BuilderModel.dll覆盖Codematic安装目录下的同名文件即可
覆盖前请先备份原文件,需要时再替换回来
