我在Windows窗体应用程序项目上收到FileNotFoundException,并显示以下消息:

Could not load file or assembly 'System.Drawing, Version=4.0.0.0, 
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. 
The system cannot find the file specified.

要复制问题:

• 选择New,Project,选择.Net Framework 2.0作为目标,并选择Windows Forms Application作为项目类型.

System.IO.FileNotFoundException was unhandled
  Message=Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

我在最近安装在Windows 8开发人员预览版上的Visual Studio 2010 SP1上得到了这个.如果我将项目属性更改为目标.Net Framework 4,则错误消失.

在Form1.resx文件中,我可以看到System.Drawing程序集的版本明确声明为2.0:

<assembly alias="System.Drawing" name="System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" …
