Hangfire Ace Downloads

Hangfire Ace packages are hosted on a private ProGet Server. Package downloads are available only for Hangfire Ace subscribers. After paying, you’ll instantly receive a link to download the Hangfire Ace binaries (non-NuGet based). Please give us 24 hours to generate your credentials for private NuGet server.

Available Packages

  • Hangfire.Throttling – concurrency and rate limiting that don’t force your workers to wait.

Configuring Feed

There are several ways to add a NuGet feed, but the main difficulty is authentication. In modern environments with NuGet 3.5+ it is possible to use environment variables to provide credentials, and it is the best way, since you’ll have the same configuration for both development machines and build servers, and for all environments, including .NET Core projects.

Simple Setup in Visual Studio

This is the simplest way to start using Hangfire Ace feed, but it will not work with Continuous Integration. To configure a private feed in Visual Studio, open Tools → NuGet Package Manager → Package Manager Settings and add a new feed with the following URL:

NuGet V3 Feed Endpoint


NuGet V2 Feed Endpoint (for older systems)


Package Manager Settings Window

Modern environments

Applies to: Visual Studio 2017, .NET Core CLI, NuGet.exe 3.5+. This will also work in Visual Studio 2015, but you’ll be prompted for credentials each time you install a package, when HangfireAce feed is selected.

Create a new file called NuGet.config in the root directory of your solution, and add the following contents.

<!-- YourSolution\NuGet.config -->
        <add key="HangfireAce" value="https://nuget.hangfire.io/nuget/hangfire-ace/v3/index.json" />
            <add key="Username" value="%HANGFIRE_LOGIN%" />
            <add key="ClearTextPassword" value="%HANGFIRE_PASSWORD%" />

The changes will take an effect only when you close the solution and re-open it. You can safely add this file to the solution control, since it does not contain any sensitive data. It’s better to set environment variables for credentials then, to not to specify them each time.

Setting environment variables

On Windows, use the setx command to add the corresponding environment variables as shown below. Please note that these commands will add environment variables for all users and may require additional privileges, but you can remove the /M switch to set them for current user only.

setx /M HANGFIRE_LOGIN your_login
setx /M HANGFIRE_PASSWORD your_password

Alternatively you can set environment variables using the System properties window, but don’t forget to re-open the command prompt to use the new values.

On *nix systems it depends on your shell program. You can use the following commands to set environment variables when using Bash.

export HANGFIRE_LOGIN=your_login
export HANGFIRE_PASSWORD=your_password

In TeamCity, use Build Parameters, in AppVeyor use secure variables in your appveyor.yml file, in Travis CI it’s possible to use encrypted variables too. I believe other continuous integration servers also have an encryption feature.


Package not found: close the solution and open it again. 401 unauthorized status returned: ensure your environment variables are set and use correct credentials. If package restore prompts for credentials, ensure environment variables are set, and you have the latest version of the NuGet client:

> NuGet.exe help
NuGet Version:

If your version less than the specified one, just update the NuGet client:

NuGet.exe update -self

If you have any problems with the setup, send an email to support@hangfire.io, I’ll be happy to help.

Build servers with NuGet < 3.5

Alternatively, you can run the following command to add a new package source using command line:

nuget sources add -Name "HangfireAce" -Source https://nuget.hangfire.io/nuget/hangfire-ace -UserName user -Password secret
