这应该取决于您正在使用的项目或语言。因此扩展相关的构建，vs文件夹，sln文件，bin文件夹等将包括在内。对于git忽略文件的完整列表，您可以检查此repo Gitignore for visual studio

有一个在线工具可以让你根据你的操作系统、IDE、语言等生成。gitignore文件。看看http://www.gitignore.io/。

在2014年8月20日，这是为Visual Studio + Windows生成的文件。

!NuGet.exe

#Ignore WebDeploy publish profiles

某些项目可能需要添加*。显到他们的视觉工作室gitignore。输入输出文件。

这是因为新项目的一些Visual Studio项目属性被设置为生成清单文件。

参见“在Visual Studio中生成清单”

但是如果您已经生成了它们，并且它们是静态的(不会随着时间而改变)，那么从.gitignore文件中删除它们是个好主意。

这就是Git for Windows这样的项目刚刚做的事情(适用于Git 2.24, 2019年第四季度)

参见Johannes Schindelin (dscho)的commit aac6ff7(2019年9月05日)。 (由Junio C Hamano—gitster—在commit 59438be中合并，2019年9月30日)

.gitignore: stop ignoring .manifest files On Windows, it is possible to embed additional metadata into an executable by linking in a "manifest", i.e. an XML document that describes capabilities and requirements (such as minimum or maximum Windows version). These XML documents are expected to be stored in .manifest files. At least some Visual Studio versions auto-generate .manifest files when none is specified explicitly, therefore we used to ask Git to ignore them. However, we do have a beautiful .manifest file now: compat/win32/git.manifest, so neither does Visual Studio auto-generate a manifest for us, nor do we want Git to ignore the .manifest files anymore.

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。

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。
