文件。但是，当我尝试此操作时，会出现以下错误：

当我尝试对VS2015文件执行此操作时，它向我显示了相同的错误，但这次

我的MonoDevelop版本是v4.0.12；有解决方法吗？

我知道MonoDevelop 5.x+/Mono4.x有xbuild/MSBuild支持工具版本12。让我们检查一下你的安装

检查Mono安装： mono--版本

Mono JIT compiler version 4.0.2 ((detached/c99aa0c Thu Jun 11 18:53:01 EDT 2015)

XBuild Engine Version 12.0
Mono, Version 4.0.2.0**

xbuild——版本

Mono JIT compiler version 4.0.2 ((detached/c99aa0c Thu Jun 11 18:53:01 EDT 2015)

XBuild Engine Version 12.0
Mono, Version 4.0.2.0**

检查您的GAC安装： gacutil-l|grep Microsoft.Build

检查是否具有MSBuild dll（路径也依赖于平台，根据需要进行更改）： 从上面的输出获取Mono安装路径，并更改下面的路径以匹配： find/Library/Frameworks/Mono.framework/Versions/4.0.2-名称“*MSBuild”

如你所见，我有12版的工具。根据需要更新安装/重新安装；-）

解决办法包括：

升级到MonoDevelop 5，它支持使用12.0版工具的项目

编辑.csproj文件并将工具版本更改为4.0
