Introduction

A good .gitignore for Visual Studio keeps source control focused on source files, solution files, and intentional project assets. The main idea is simple: commit code and project definitions, but ignore user-specific settings, build output, caches, and generated artifacts that can be recreated.

What Visual Studio Usually Generates

A Visual Studio workspace tends to produce several kinds of files you do not want in Git:

• build output such as bin/ and obj/
• user-specific settings such as *.user and *.suo
• IDE metadata such as .vs/
• test output and coverage artifacts
• package restore caches or temporary generated files

Those files either vary from machine to machine or change too often to be useful in version control.

A Practical Starting Point

Here is a compact .gitignore that works for many C# and Visual Studio solutions:

1# Visual Studio workspace metadata
2.vs/
3*.suo
4*.user
5*.userosscache
6*.sln.docstates
7
8# Build output
9[Bb]in/
10[Oo]bj/
11[Dd]ebug/
12[Rr]elease/
13x64/
14x86/
15
16# Test results
17TestResults/
18*.trx
19*.coverage
20
21# Logs and temporary files
22*.log
23*.tmp
24
25# NuGet package folders for older packages.config workflows
26packages/
27
28# Rider or VS Code metadata if the team does not track it
29.idea/
30.vscode/

This is a baseline, not a law. Real projects often need a few additions or removals depending on the stack.

What You Usually Should Keep

Ignoring too much is just as harmful as ignoring too little. In most Visual Studio repositories, you should keep files such as:

• '.sln'
• '.csproj, .vbproj, or other project files'
• source code under *.cs, *.ts, *.js, and similar
• configuration that is intentionally shared
• migration files, scripts, and assets required to build the project

If a new teammate cannot clone the repo and build the solution because a necessary file was ignored, the .gitignore is too aggressive.

NuGet and Modern .NET Projects

One area that often causes confusion is NuGet.

For older projects that use packages.config, ignoring the local packages/ folder is common because packages can be restored.

For SDK-style projects with modern package restore, the important source files remain the project files themselves, not the local caches. In those projects, you usually still ignore generated package directories and machine-local caches, but you keep the project file that declares the package references.

The same principle applies elsewhere: keep declarations, ignore recreatable downloads.

Existing Tracked Files Are Not Affected Automatically

.gitignore only prevents new untracked files from being added. If bin/ or .vs/ was already committed earlier, adding it to .gitignore will not remove it from the repository by itself.

You would need to stop tracking it explicitly:

git rm -r --cached .vs bin obj
git commit -m "Stop tracking generated Visual Studio files"

That is a common gotcha when teams add a .gitignore after the repository already exists.

Prefer Project-Level Rules Over Global Surprises

Git supports a global ignore file on each developer machine, and that can be useful for editor backups or OS-specific clutter. But project-specific rules such as .vs/, bin/, and obj/ usually belong in the repository’s own .gitignore so every teammate gets consistent behavior.

A repository-level .gitignore should explain the project’s needs. A global ignore should only handle personal machine clutter.

Common Pitfalls

The biggest mistake is committing generated folders such as bin/, obj/, or .vs/. They create noisy diffs and pointless merge conflicts.

Another common issue is ignoring too broadly. For example, ignoring all config files can accidentally hide a shared configuration file that the application actually needs.

Teams also sometimes forget that .gitignore does not untrack existing files. If a bad artifact is already in the index, it needs a git rm --cached cleanup step.

Finally, copying a giant template blindly can produce a confusing file full of rules that do not match the actual project. Start from a solid template, but trim it to the repository you are maintaining.

Summary

• A Visual Studio .gitignore should keep generated and machine-specific files out of Git.
• Common ignores include .vs/, bin/, obj/, *.user, and test artifacts.
• Keep solution files, project files, source code, and shared configuration.
• '.gitignore does not remove files that are already tracked.'
• Use a template as a starting point, then adapt it to the real project rather than keeping unnecessary rules forever.
