I installed Monogame, and when trying to run a very simple hello world style game I get this exception. I understand that there are several posts on stack overflow regarding this error, but am still puzzled as to how to fix this. Do I need to uninstall .Net and reinstall a different version? If so, how do I do that?

推荐答案

这样的错误，如果你有提及该做的不可以附带Xamarin.iOS组件发生会。这对 System.Drawing.dll程序的情况。

Such errors will occurs if you have reference to assemblies that do not ship with Xamarin.iOS. That's the case for System.Drawing.dll.

在你的情况可能是因为你的项目有两个引用 monotouch.dll 和 MonoMac.dll 这不是要去工作。

In your case it's likely because your project has references to both monotouch.dll and MonoMac.dll and that's not gonna work.

您需要建立单独的项目对每个目标，即一个用于iOS系统（monotouch.dll）和OSX（MonoMac.dll）。

You need build separate projects for each target, i.e. one for iOS (monotouch.dll) and for OSX (MonoMac.dll).

从可以共享源代码和/或组件（共享逻辑）每个项目。这两个项目还需要包括特定于平台的代码和引用。

From each project you can share source code and/or assemblies (for shared logic). Both projects also needs to include platform specific code and references.

在结束了一个很大的共享代码（源或组件）与代码的一些平台特定位。

In the end up with a lot of shared code (in source or assemblies) with a few platform specific bits of code.
