在MSDN网站上，它清楚地说明了这一点

解决方案用户选项(.suo)文件包含每个用户的解决方案 选项。该文件不应检入源代码控制。

所以我想说，在把东西签入源代码控制时，忽略这些文件是非常安全的。

这似乎是微软对此事的看法:

添加(并编辑).suo文件到源代码控制

I don't know why your project stores the DebuggingWorkingDirectory in the suo file. If that is a user specific setting you should consider storing that in the *.proj.user filename. If that setting is shareable between all users working on the project you should consider storing it in the project file itself. Don't even think of adding the suo file to source control! The SUO (soluton user options) file is meant to contain user-specific settings, and should not be shared amongst users working on the same solution. If you'd be adding the suo file in the scc database I don't know what other things in the IDE you'd break, but from source control point of view you will break web projects scc integration, the Lan vs Internet plugin used by different users for VSS access, and you could even cause the scc to break completely (VSS database path stored in suo file that may be valid for you may not be valid for another user).

使用Rational ClearCase，答案是否定的。只有.sln & .*proj应该在源代码控制中注册。

我不能为其他供应商负责。如果我没记错的话，这些文件是“用户”特定的选项，您的环境。

我们不提交二进制文件(*.suo)，但我们提交.user文件。例如，.user文件包含用于调试项目的启动选项。你可以在“Debug”选项卡的项目属性中找到启动选项。我们在一些项目中使用了NUnit，并配置了NUnit -gui.exe作为项目的开始选项。如果没有.user文件，每个团队成员都必须单独配置它。

希望这能有所帮助。

These files contain user preference configurations that are in general specific to your machine, so it's better not to put it in SCM. Also, VS will change it almost every time you execute it, so it will always be marked by the SCM as 'changed'. I don't include either, I'm in a project using VS for 2 years and had no problems doing that. The only minor annoyance is that the debug parameters (execution path, deployment target, etc.) are stored in one of those files (don't know which), so if you have a standard for them you won't be able to 'publish' it via SCM for other developers to have the entire development environment 'ready to use'.

这些文件是特定于用户的选项，应该独立于解决方案本身。Visual Studio会根据需要创建新的，所以它们不需要检入到源代码控制中。实际上，最好不要这样做，因为这样可以让开发人员根据自己的需要定制自己的环境。
