dotnet-outdated

This is a continuation of the original dotnet-outdated tool created by Jerrie Pelser.

If you already have the original dotnet-outdated tool installed you need to run dotnet tool uninstall --global dotnet-outdated before installing this version.

Overview

When using an IDE such as Visual Studio, it is easy to find out whether newer versions of the NuGet packages used by your project is available, by using the NuGet Package Manager. However, the .NET Core command-line tools do not provide a built-in way for you to report on outdated NuGet packages.

dotnet-outdated is a .NET Core Global tool that allows you to quickly report on any outdated NuGet packages in your .NET Core and .NET Standard projects.

dotnet-outdated

Installation

Download and install the .NET Core 3.1, 5 , 6 or 7 SDK. Once installed, run the following command:

dotnet tool install --global dotnet-outdated-tool

If you already have a previous version of dotnet-outdated installed, you can upgrade to the latest version using the following command:

dotnet tool update --global dotnet-outdated-tool

Specifying the path

You can run dotnet-outdated without specifying the Path argument. In this case, it will look in the current directory for a solution (.sln) and if one is found it will analyze that solution. If no solution is found it will look for a project (.csproj or .fsproj) and if one is found it will analyze that project. If more than one solution or project is found in the current folder, dotnet-outdated will report an error.

You can also pass a directory in the Path argument, in which case the same logic described above will be used, but in the directory specified.

Lastly, you can specify the path to a solution (.sln) or project (.csproj or .fsproj) which dotnet-outdated must analyze.

Upgrading packages

dotnet-outdated can automatically attempt to upgrade any outdated packages to the latest version by passing the -u|--upgrade option. You can let dotnet-outdated prompt you for each outdated package by using the -u:prompt option.

Working with secure feeds

dotnet-outdated supports secure NuGet feeds, such as MyGet. It is suggested that you add these to your sources using the source command of the NuGet CLI. For secure feeds, you can do one of the following:

Add a pre-authenticated URL.
Specify the username and password for the feed using the -UserName and -Password options of the nuget sources command.
Use a credential provider like the Azure Artifacts credential provider.

dotnet-outdated supports computer-level, user-level and project-level configuration files.

Using credential providers requires an environment variable DOTNET_HOST_PATH that is set to the path to the dotnet executable (e.g., /usr/local/share/dotnet/dotnet). Some versions of the .NET Core SDK do this for you at runtime, some do not. You will get an error message explaining this if the process finds it missing.

Issues on macOS

In my testing, I ran into issues on macOS where the location of the user-level configuration file was not detected correctly. If you run into problems where dotnet-outdated does not appear to pick up your feeds correctly, please add the source to a project-level configuration file.

Also, on macOS and Linux, the password needs to be stored in clear text. You can do this by passing the -StorePasswordInClearText option to the nuget sources command.

Handling pre-release versions

dotnet-outdated allows you to specify whether to use pre-release versions of packages or not by passing the -pre|--pre-release option.

The default value of Auto will determine whether to use pre-release versions of a package based on whether the referenced version itself is a pre-release version. If the referenced version is a pre-release version, dotnet-outdated will include newer pre-release versions of the package. If the referenced version is not a pre-release version, dotnet-outdated will ignore pre-release versions.

You can also tell dotnet-outdated to always include pre-release versions by passing the Always value for this option. Conversely, you can tell it to never include pre-release versions by passing the Never value.

Locking to the current major or minor release

dotnet-outdated allows you to lock the version to the current major or minor version by passing the -vl|--version-lock option.

The default value of None will return the absolute latest package, regardless of whether it is a major or minor version upgrade.

Passing a value of Major will only report on later packages in the current major version range. For example, if the current version for a package is 4.1.0, dotnet-outdated will only report on later packages in the 4.x version range.

Passing a value of Minor will only report on later packages in the current minor version range. For example, if the current version for a package is 4.1.0, dotnet-outdated will only report on later packages in the 4.1.x version range.

Reporting on transitive dependencies

dotnet-outdated supports reporting on transitive dependencies as well. These are NuGet packages on which the NuGet packages directly referenced by your application depends. To enable reporting on transitive dependencies, you can pass the -t|--transitive option.

You can also specify how many levels deep it should analyze transitive dependencies with the -td|--transitive-depth option. You can pass an integer value for this option (the default value is 1).

Be careful with these options!. If you try and analyze dependencies too many levels deep, the analysis can take a very long time.

Failing when updates are available

dotnet-outdated can be easily incorporated into your build process. You can optionally enable a non-zero return code when updates are found to make failing a build easy to configure. To enable this option you can pass the -f|--fail-on-updates option.

Auto-references

Before version 1.2 of dotnet-outdated, it used to include automatically referenced packages in the output. The automatically referenced packages are typically your framework packages, such as Microsoft.NETCore.App or NETStandard.Library. It does not make sense reporting on these as outdated since you should target a new framework to have these updated.

From version 1.2, if you want these packages reported, you can pass the -i|--include-auto-references option. These packages will also be denoted with the text [A] appearing in the output after the package name.

Saving results to a file

You can save the results of dotnet-outdated to a file by specifying the name of an output file using the -o|--output option. By default, the results will be saved in JSON format. You can specify an alternate format using the -of|--output-format option.

Including and excluding packages

You can choose to include only specific packages by using the -inc|--include option. Only packages whose name contain the specified value will be included. For example, if you only want to analyze packages containing the value "microsoft", you can use the command dotnet outdated --include microsoft. This option can be passed in multiple times: each package will be evaluated against all the filters. One single match is enough to include that package.

Conversely, you can exclude specific packages by using the -exc|--exclude option. In this case all packages will be analyzed except packages whose name contain the specified value. For example, if you want to exclude packages containing the value "microsoft", you can use the command dotnet outdated --exclude microsoft. This option can be passed in multiple times: each package will be evaluated against all filters. One single match is enough to exclude that package.

Please note that for both include and exclude, the comparison is culture and case insensitive.

Only listing new version of packages older than a specified the number of days

There are some packages that have new updates almost on daily basis, and it might slow down development and will break all CI builds if dotnet-outdated is integrated into the CI - so the development team needs to urgently react on every single update.

This command will let the developers finish their job and update the packages on their own pace.

For failing CI builds, a proposed protocol is to have another CI build which will be scheduled weekly to inform developers of new packages, and they will react accordingly.

Also, some companies/users do not feel comfortable jumping directly on the newest versions, as they might contain some bugs, and might want to wait for some time before updating to the newest package.

FAQ

Why are unrelated changes made to .csproj files when running with `-u`?

dotnet-outdated does not make any changes to .csproj files directly. Instead, it runs dotnet add package to update packages, so that command is responsible for all changes made. To track issues related to this command, head over to the .NET CLI repo

Why I am getting an error about required library hostfxr.dll/libhostfxr.so/libhostfxr.dylib not found?

If you download the .NET Core CLI as a .zip/.tar.gz and extract it to a non default location, then you may encounter this error after installing and launching dotnet-outdated.

You can fix this error by setting the DOTNET_ROOT environment variable to point to the location of your .NET Core CLI installation. For more information, please refer to this blog post.
