【问题描述】：
我最近安装了elementary OS Luna。我们学校有 C# 课程，所以我想使用 Mono 和 MonoDevelop。
我添加了 directhex/monoxide PPA 存储库，然后我使用“sudo apt-get install mono”安装了 Mono。
mono -V 返回：
Mono JIT compiler version 3.2.1 (Debian 3.2.1+dfsg-1~pre2)
Copyright (C) 2002-2012 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com
TLS: __thread
SIGSEGV: altstack
Notifications: epoll
Architecture: amd64
Disabled: none
Misc: softdebug
LLVM: supported, not enabled.
GC: sgen
然后，我安装了 MonoDevelop，使用命令“sudo apt-get install monodevelop”，我的版本是 3.0.1。然后，我安装了 xterm，使用“sudo apt-get install xterm”。
我的 MonoDevelop 运行正常，直到我想运行我的应用程序。
当我使用 F5 或 Ctrl+F5 时，它会返回：

我真的很想在学校使用 Linux，但是这个错误迫使我回到 Windows，请帮助我 :(.
另外，对不起，我的英语不是我的母语。感谢您的帮助。

建议您在 Windows 或 Mac 上使用 Mono 3 以及 Xamarin Studio。到目前为止，我发现在 Linux 上使用它令人沮丧，因为我必须从源代码构建 Mono，以及 MonoDevelop。
