在Visual Studio 2015 Update 3中，以及今天(2016-10-24)更新的Git扩展，由Visual Studio生成的.gitignore是:

使用Visual Studio添加.gitignore

打开Visual Studio和需要忽略文件的解决方案。从顶部菜单选择Git > Settings。

上面将打开Visual Studio的选项，选择源代码控制> Git全局设置。从左侧列表中选择Git Repository Settings，然后单击“忽略文件”的“添加”按钮。

上面的代码将添加(并提交)一个.gitignore文件，其中包含典型Visual Studio设置中忽略的所有适当文件。

https://elanderson.net/2020/10/add-git-ignore-to-an-existing-visual-studio-solution-new-git-experience/

注意，如果你的repo根目录中已经有一个.gitignore文件，“添加”按钮将显示“编辑”，按下该按钮将只是打开文件而不更新它，这不是很有帮助。在这种情况下，您可以首先重命名您的.gitignore文件，单击Add按钮，取消新的.gitignore文件，然后按照您喜欢的方式合并保存的副本更改。

这里的聚会很晚，但我也发现我使用以下方法。有些可能只用于在按到公共远程时隐藏敏感文件。

#Ignore email files delivered to specified pickup directory
*.eml

#Allow NuGet.exe (do not ignore)
!NuGet.exe

#Ignore WebDeploy publish profiles
*.Publish.xml

#Ignore Azure build csdef & Pubxml files
ServiceDefinition.build.csdef
*.azurePubxml

#Allow ReSharper .DotSettings (for non-namespace-provider properties)
!*.csproj.DotSettings

#Ignore private folder
/Private/

参见官方GitHub的“有用的。gitignore模板集合”。

Visual Studio的.gitignore可以在这里找到: https://github.com/github/gitignore/blob/main/VisualStudio.gitignore

您可以通过转到团队资源管理器中的设置视图，然后选择存储库设置来创建或编辑您的.gitignore文件。选择编辑你的。gitignore。

它会自动创建过滤器，忽略所有VS特定的构建目录等。

而你应该保留你的NuGet包。配置文件，你应该排除packages文件夹:

#NuGet
packages/

我通常不将二进制文件或从我的源代码生成的任何东西存储在源代码控制中。然而，对此有不同的意见。如果它使构建系统更容易，那么就这么做吧!然而，我认为您没有对这些依赖项进行版本控制，因此它们只会占用存储库中的空间。将二进制文件存储在一个中心位置，然后依赖于包。在我看来，配置文件来指示需要哪个版本是一个更好的解决方案。
