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.

我在c#项目中使用下面的.gitignore。在需要时添加其他模式。

[Oo]bj
[Bb]in
*.user
*.suo
*.[Cc]ache
*.bak
*.ncb
*.log 
*.DS_Store
[Tt]humbs.db 
_ReSharper.*
*.resharper
Ankh.NoLoad

我明白这是一个老问题，还在分享一个信息。在Visual Studio 2017中，只需右键单击解决方案文件，并选择将解决方案添加到源代码控制

这将向源文件夹中添加两个文件。

.gitattributes .gitignore

这是最简单的方法。

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

正如另一张海报所提到的，Visual Studio将其生成为.gitignore的一部分(至少对于MVC 4):

# SQL Server files
App_Data/*.mdf
App_Data/*.ldf

因为你的项目可能是你的解决方案的一个子文件夹，而.gitignore文件存储在解决方案根目录中，这实际上不会触及本地数据库文件(Git在projectfolder/App_Data/*.mdf中看到它们)。为了解释这一点，我修改了这些行:

# SQL Server files
*App_Data/*.mdf
*App_Data/*.ldf

对于那些对微软认为应该包含在gitignore中感兴趣的人，这里是Visual Studio 2013 RTM在创建一个新的Git-Repository时自动生成的默认gitignore:

## Ignore Visual Studio temporary files, build results, and
