Get TFS to ignore my packages folder
Managing dependencies is a crucial aspect of software development, and with projects growing in complexity, so does the size of our dependency folders. In Team Foundation Server (TFS), large folders like “packages” can bloat your repository, slowing down operations and consuming valuable storage. This post explores strategies to efficiently manage dependencies and get TFS to ignore your packages folder, leading to a smoother, faster workflow. Ignoring unnecessary files in your source control is a best practice that keeps your repository clean and focused, improves performance, and minimizes storage costs. Let’s dive into practical solutions for a more streamlined TFS experience.
Using .tfignore
.tfignore is a powerful tool for excluding specific files and folders from being tracked by TFS. It operates similarly to .gitignore and offers granular control over what gets included in your repository. By creating a .tfignore file, you can specify patterns to match files or folders that should be ignored, freeing up valuable space and improving performance. This is particularly useful for excluding large, automatically generated directories like the “packages” folder, which typically contains numerous dependencies that don’t need to be version-controlled directly.
Creating a .tfignore file is simple. Just create a text file named “.tfignore” in the root of your repository or any subfolder. Each line in the file specifies a pattern to match. For example, to ignore the packages folder, simply add packages/ to a new line in the .tfignore file. TFS will then automatically ignore this folder and its contents.
NuGet Package Restore
Leveraging NuGet’s package restore feature is a key element in managing dependencies effectively. Instead of storing packages directly in your repository, NuGet allows you to restore them on demand during the build process. This dramatically reduces repository size and improves build times. By configuring your projects to automatically restore packages during the build, you can ensure that all necessary dependencies are available without cluttering your source control.
Package restore is typically enabled by default in newer project templates. However, if you’re working with older projects, you might need to enable it manually. This usually involves checking a setting in your project’s properties or NuGet settings. Once enabled, NuGet will automatically download and install the required packages during the build, based on the project’s package configuration file (packages.config or PackageReference).
Best Practices for Dependency Management
Beyond simply ignoring the packages folder, adopting a robust dependency management strategy is crucial for long-term project health. This includes regularly reviewing and updating dependencies, using a centralized package management system, and implementing clear versioning policies. Staying on top of your dependencies minimizes the risk of vulnerabilities and ensures compatibility across your project.
For instance, using a package management solution like NuGet allows you to centrally manage dependencies and easily update them across multiple projects. This reduces the risk of using outdated or conflicting libraries, and simplifies the process of keeping your project up-to-date with the latest security patches and feature enhancements. Regularly auditing your dependencies is also a best practice to ensure that you’re only using what’s necessary and that all dependencies are properly licensed.
Alternatives to .tfignore
While .tfignore is a convenient solution, other approaches exist for managing dependencies and excluding files from TFS. One option is to use the “Cloaked” feature in TFS, which allows you to exclude specific files or folders from being downloaded to your local workspace. This is useful for very large files or folders that you don’t need to work with directly. Another option is to use a separate repository for dependencies, though this adds complexity and requires careful management.
Choosing the right approach depends on your specific needs and project structure. For most cases, .tfignore and NuGet package restore provide a robust and efficient solution. If you’re dealing with exceptionally large files or unique project requirements, exploring alternative solutions like cloaking or separate repositories might be necessary. Understanding the pros and cons of each approach will help you make the best decision for your team and project.
- Use .tfignore to exclude unnecessary files and folders.
- Leverage NuGet Package Restore for efficient dependency management.
- Create a .tfignore file.
- Add “packages/” to the .tfignore file.
- Check in the .tfignore file.
Consider these questions to optimize your .tfignore strategy: What file types are generated during the build process? Which of these files are essential for source control? By identifying and excluding non-essential files, you can significantly reduce repository bloat.

FAQ
Q: Can I use wildcards in .tfignore?
A: Yes, you can use wildcards like and ? to match multiple files or folders in .tfignore.
Q: What happens if I accidentally ignore a necessary file?
A: You can easily un-ignore a file by removing the corresponding pattern from your .tfignore file.
Question & Answer :
I’m trying to get TFS (2013) to ignore my packages folder. I passionately don’t want it source controlled as I’m using NuGet and it’s great!
I’ve tried cloaking (doesn’t seem to work), I’ve tried adding .tfignore files - nothing is ignored. Why don’t the TFS team just add an option to permanently ignore a folder or file like lots of the Subversion clients do?!
Here’s the deal: We have to tell both NuGet and TFS to ignore the packages, because NuGet is trying to do source-control related stuff that it absolutely shouldn’t be doing (bad form, Microsoft!). So you have to do two things.
First, add a file named .tfignore to the solution folder (note the lack of s after the tf). Its contents should be as follows:
\packages
That tells TFS to ignore your packages folder. Now, you would think that this would also ignore the repositories.config file. But it won’t. Why? Who knows, the ways of Microsoft are strange and mysterious. Actually, I think it’s part of the NuGet stuff I outline below, but if that ever gets fixed in the future and you want to keep the repositories.config file instead of letting VS regenerate it, you should be able to use this:
\packages !\packages\repositories.config
OK, so now thanks to our .tfignore file, TFS is ignoring your packages. Everything is fine, right? WRONG, because NuGet is mucking around with your source control and adding the packages to your pending changes. So now let’s tell NuGet to cut it out already.
Create a folder called .nuget in the root of your solution folder.1 Now, create a file called NuGet.config, and put it in this new folder2. Its contents should look like this:
<?xml version="1.0" encoding="utf-8"?> <configuration> <solution> <add key="disableSourceControlIntegration" value="true" /> </solution> </configuration>
And now your packages should stay out of source control. Just remember to add the NuGet.config and .tfignore files to source control so they never get lost.
EDIT: If you’re having issues, you may want to delete your packages folder, check in that change, and then go through the steps above.
ALSO EDIT: It looks like this won’t happen with newer versions of Nuget. So maybe if you switch to VS/TFS 2017 this issue will clear up without jumping through the above hoops.
1. Add the folder using Source Control Explorer; right-click the solution->Add folder->.nuget
2. When I figured this out using VS 2013, I found the NuGet.config had to go in the .nuget folder. Even if you already have a NuGet.config file in the root of your solution folder (because, say, your company has an internal nuget feed). However, some in the comments have indicated that it works fine in the solution root in VS 2015. Personally, I switched to using TFS in git mode, so I can’t test. Additionally, if you do have a custom feed, ensure that you have both the custom feed and nuget.org as keys in the Nuget.config file, or sometimes TFS will randomly decide it can’t restore the packages.
