MonoDevelop无法导入VS2013 / 2015解决方案

Question

我正在打开一个.sln文件，我从VS2013转移到MonoDevelop。但是，当我尝试这个时，它会给我以下错误：

1. Project 'foo' has a different ToolsVersion than the containing solution.
2. Error while trying to load the project '/path/to/foo.csproj': Unknown ToolsVersion '12.0'
3. [repeat 2 for every project in the solution]

当我尝试为VS2015文件执行此操作时，它会向我发送相同的错误，但此时ToolsVersion为14.0。

我的MonoDevelop版本是v4.0.12;有解决方法吗？

Answer 1

我知道MonoDevelop 5.x + / Mono 4.x有xbuild / MSBuild支持Toolsversion 12.所以请检查你的安装。

检查Mono安装：

mono --version

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

xbuild --version

XBuild Engine Version 12.0
Mono, Version 4.0.2.0**

检查您的GAC安装：

gacutil -l | grep Microsoft.Build

检查您是否拥有MSBuild dll（路径也取决于平台，根据需要进行更改）：

cat `which xbuild`

#!/bin/sh
exec /Library/Frameworks/Mono.framework/Versions/4.0.2/bin/mono $MONO_OPTIONS /Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/xbuild/12.0/bin/xbuild.exe "$@"

从上面的输出中获取Mono安装路径并更改下面的路径以匹配：

查找/Library/Frameworks/Mono.framework/Versions/4.0.2 -name＆＃34; * MSBuild＆＃34;

/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/4.5/MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/policy.0.2.Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/policy.0.3.Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/policy.0.4.Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/policy.0.5.Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/gac/policy.0.6.Mono.Addins.MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/xbuild/12.0/bin/MSBuild
/Library/Frameworks/Mono.framework/Versions/4.0.2/lib/mono/xbuild/14.0/bin/MSBuild

因此，您可以看到我有工具版本12.根据需要更新安装/重新安装; - ）

Answer 2

解决方法是：

1. 升级到支持使用工具版本12.0的项目的MonoDevelop 5

2. 编辑.csproj文件并将工具版本更改为4.0

   ＆lt; Project ToolsVersion =“4.0”

如果您选择2.那么您必须在此更改后查看项目是否仍然构建。
