我有一个自定义包创建为Visual Studio扩展。对于我的项目文件，我创建了两个新的自定义属性页面。只有这两个显示在我的项目的属性窗口中。一切都可以在属性页面级别使用Dirty标志工作，这意味着，当我更改某些内容时，单个选项卡设置为脏，并且当存储信息时，它会变回不脏。
但我的问题是：一旦我打开属性页面，视图的主Tab（显示项目名称）包含脏标志（一个小星星），我无法解决这个问题。我必须在哪个属性中设置“不脏”，以便整个页面显示为“不脏”。
祝你好运， 马丁

我记得MSDF论坛上有一些相关的主题（Visual Studio可扩展性） - 请参阅here。
我不太确定，但我在“Need sample code for custom property pages”主题中在MSDN论坛（VSX论坛）上发布的示例对我来说很合适。
P.S。而且您始终可以报告VSX bug on Microsoft Connent。
请参阅下面的自定义属性页示例，其余相关代码示例也可用于上面提到的MSDN线程。
