.net - "Message"任务未找到

Question

突然，当我今天通过 Visual Studio 2008 解决方案打开并尝试重建所有内容时，出现以下错误:

The "Message" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with in the project file, or in the *.tasks files located in the "D:\WINDOWS\Microsoft.NET\Framework\v3.5" directory

我什么都不明白。你能指导一下吗。

根据以下评论(感谢@Thomas 和@Vikram)，重新启动 Visual Studio 似乎也解决了该问题。
