System.Drawing.BitmapSuffixInSameAssemblyAttribute 单声道缺失
System.Drawing.BitmapSuffixInSameAssemblyAttribute missing in mono
我有一个 .NET MVC 5 应用程序，我已经在 Windows 中开发了一段时间。我希望使用 Mac 的网页设计师能够 运行 并在他的 Mac.
上本地编辑应用程序
如果没有构建 Windows 虚拟机，Mono + Monodevelop/Xamarin Studio 似乎是完成此任务的最佳方式。
当我们第一次构建项目时，我们得到了an error about the System.Web.Entity.dll reference not loading. We fixed that。
但是现在，我们收到一个错误，指出 System.Drawing 命名空间中缺少某些内容。
System.TypeLoadException

我的设计师如何 运行 这个 .NET MVC 5 应用程序在他的 Mac 上本地运行？
我已经为 Mono 的 BCL 中缺失的类型实现了存根，并提出了 a pull request。
因为它已经被接受和合并，这个问题应该在 Mono 的 v.NEXT 版本（很可能命名为 4.4）中得到解决。
