你不需要添加这些——它们包含每个用户的设置，其他开发人员不会想要你的副本。

默认情况下，Microsoft的Visual SourceSafe在源代码控制中不包括这些文件，因为它们是用户特定的设置文件。如果您使用SVN作为源代码控制，我会遵循这个模型。

No.

我只是想要一个简短的答案，但没有。

其他人解释说，不，你不希望在版本控制中使用这个。你应该配置你的版本控制系统来忽略这个文件(例如通过一个.gitignore文件)。

要真正理解其中的原因，看看这个文件中到底有什么会有所帮助。我编写了一个命令行工具，可以让您查看.suo文件的内容。

在你的机器上安装它通过:

dotnet tool install -g suo

它有两个子命令，键和视图。

suo keys <path-to-suo-file>

这将转储文件中每个值的键。例如(节选):

nuget
ProjInfoEx
BookmarkState
DebuggerWatches
HiddenSlnFolders
ObjMgrContentsV8
UnloadedProjects
ClassViewContents
OutliningStateDir
ProjExplorerState
TaskListShortcuts
XmlPackageOptions
BackgroundLoadData
DebuggerExceptions
DebuggerFindSource
DebuggerFindSymbol
ILSpy-234190A6EE66
MRU Solution Files
UnloadedProjectsEx
ApplicationInsights
DebuggerBreakpoints
OutliningStateV1674
...

如您所见，许多IDE特性都使用这个文件来存储它们的状态。

使用view命令查看给定键的值。例如:

$ suo view nuget --format=utf8 .suo
nuget

?{"WindowSettings":{"project:MyProject":{"SourceRepository":"nuget.org","ShowPreviewWindow":false,"ShowDeprecatedFrameworkWindow":true,"RemoveDependencies":false,"ForceRemove":false,"IncludePrerelease":false,"SelectedFilter":"UpdatesAvailable","DependencyBehavior":"Lowest","FileConflictAction":"PromptUser","OptionsExpanded":false,"SortPropertyName":"ProjectName","SortDirection":"Ascending"}}}

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).

.user是用户设置，我认为.suo是用户选项的解决方案。您不希望这些文件处于源代码控制之下;它们将为每个用户重新创建。
