Deploying NuGet Packages to VSTS (Visual Studio Team Services)

Managing project dependencies can be complicated, from handling shared libraries, 3rd party libraries, homebrew libaries and forks of open source libraries. There is a need for just about every project regardless of size to manage these libraries with a Package Manager. Fortunately most 3rd Party Libraries are on NuGet or some other public Package Management feed so we don’t have to manage them. Getting your private packages on your own private NuGet server is now easier then ever and with the tools built into VSTS you can create automated builds that deploy changes to your libraries to that package management server.

Package Mangement Extension

Visual Studio Team Services (VSTS) has all sorts of extensions that have utilized the APIs provided to help simplify workflows. The Package Mangement Extension can use npm or NuGet, we are going to focus on NuGet.

Add Extension

Let’s get started on installing the Package Management Extension into our VSTS Account!!

  1. Log into the home page of your VSTS account where the address would be something like http://YourAccount.visualstudio.com/
  2. Navigate to your account settings -> Extensions 

  3. Click in the top right corner of the screen
  4. Search for the Package Management Extension
  5. Select the Package Management Extension and install it

Configure Package Manager

Now that the extension is properly added to your VSTS account let’s configure it.

  1. Log into the home page of your VSTS account where the address would be something like http://YourAccount.visualstudio.com/
  2. Navigate to your project that you want to configure
  3. In the project portal navigate to Build & Release -> Packages 
  4. Click the  button
    1. Fill out the New Feed from specifying your Feed Name and Access Rights
  5. Click the  button to view your connection details to the newly created Package Management Feed
    1. This button will provide everything you need for configuring the NuGet or npm
    2. Feed location, how to get credentials, etc

Build Process

Now that our Package Management Extension is properly installed into our VSTS Account and we have configured our new feed we can start setting up our Build Enviornment to Deploy and Consume packages.

Deploy Package

Depending on your environment it may be useful to deploy pre-release packages vs production ready released packages. A pre-release package could be useful for deploying a dev version of your package for another team to consume while you finish everything up. It is important to note that I ran into lots of issues trying to consume a Pre-Releas package in our Automated Build, so I would recommend using Released Packages over Pre-Release. I’ll let you decide the best pre-release/release process.

To see the differences in building a Release vs Pre-Release package jump to steps 11 and 12 below

  1. Save the package feed path that we grabbed from the last step of Configure Package Manager, we will need that soon.
  2. Navigate to your projects Build & Release -> Builds
  3. Click the  button to start creating a new build.
  4. In the Create new build definition window select the Visual Studio Build Template

    1. Connect the build to the apprioprate source control location and selecte the  button to create your build template
  5. Select the button and add the following build steps
    1. Package -> NuGet Packager 
    2. Package -> NuGet Publisher 
  6. Configure the NuGet Packager
  7. Select the NuGet Packager Build Step
  8. Update the Path to csproj or nuspec file(s) to pack to the apprioprate file
  9. Specify your Package Folder, I used $(Build.StagingDirectory)\compiledPackages
    1. The next build step depends on this file location so make sure the agent will be able to access the file in both steps.
  10. If your .csproj file has project dependencies make sure you check Include referenced projects under Pack options
  11. Choose your deployment mode (Pre-Release)
    1. In Pack options you will see the option `Automatic package versioning
    2. Select the ‘Use the date and time
  12. Choose your deployment mode (Release)
    1. Select Use the Build Number
    2. Validate that your build number is a proper #.#.#.# build number, this can be set in the General Tab by specifying the Build Number format
    3. We specify $(MajorVersion) and $(MinorVersion) in our build variables so our build number looks like this: $(MajorVersion).$(MinorVersion).$(Year:yy)$(DayOfYear)$(Rev:.rr)
  13. Select NuGet Publisher
  14. Update our Path/Pattern to nupkg to match the location from step 9
    1. Ours looks like this: $(Build.StagingDirectory)\compiledPackages\*.nupkg
  15. Select the Feed Type of Internal NuGet Feed 
  16. Update the Internal Feed Url to the feed location you found from 
  17. Save your build and test it out, if your build steps all run successfully you are now deploying new NuGet packages from this build.
    1. You can configure you build however you want
    2. When I set this up I chose to update our NuGet package on check in

Going back to your feed defition from earlier will show you a list of all the packages

Pitfalls and Issues

While playing with the Pre-Release package deployment I ran into some issues that you may or may not run into:

  • I was not able to consume a pre-release package in a build, yet I was able to consume it through Visual Studio

Consume Package

Now that our package is being deployed properly we need to make some updates to our VSTS Builds that depend on the new NuGet feed. After you go through and update your package sources in Visual Studio and get everything working locally you will notice your build is not working. This is because your build needs an updating NuGet.config file to tell the build where to retrieve it’s packages from.

Update the Config File

  • In your Source Directory navigate to your .nuget/NuGet.config file
    • This file is typically not included in your solution
    • This file should be located in the root directory
    • If this file is not their create the folder .nuget and the config file inside of it NuGet.config

<?xml version="1.0" encoding="utf-8"?>

    <!-- Public NuGet Feed -->
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />

    <!-- Your New Private NuGet Feed -->
    <add key="Your-Feed-Name" value="https://YourAccount.pkgs.visualstudio.com/_packaging/Your-Feed-Name/nuget/v3/index.json" />

Update Build

Now that our config file has been updated and checked in, we will need to update our build definition to use our updated .nuget/NuGet.config file.

  1. Navigate to your project’s Build Definitions
  2. Select the Build that needs to consume the new packages
  3. Select your NuGet Package Restore Build Step 
  4. Update the Path to NuGet.config by selecting thebutton and selecting the path to your NuGet.config file.
  5. Test your build out, it should now properly pull your packages from your private NuGet Server
