  • Xavier: Terugverwijzen naar “Marketing versioning”
  • Start with empty MVC template + addNuGet.ServerpkgRun siteDrop pkgs in packages folderRefresh browserFeed toevoegen in VS & show pkgs
  • Inloggen en feed aanmakenPackage pushen vanuit NPEFeed toevoegen aan VSOp MyGet feed security instellenPackage installen in VS en tonen dat er basic auth bijkomtPackage van NuGet toevoegen op MyGet en tonen dat je alle dependencies kan meepakken, mirroring, … en dat je ook gewoon van uw packages.config kan toevoegen
  • - Het feit dat NuGet.org geen garanties biedt op content- Wat als mensen packages verwijderen? BUILD breaks, DEVS unhappy again
  • Now isnot the time to take a nap (NaaP) NuGet is more than a package (system), it’s a protocol to:Distributesfunctionality (automateanything!, cfrScaffolding!)Distribute websites (akadeployments!)Distribute software in general 

  • Organize Your Chickens NuGet for the EnterpriseAPRIL 16, 2012 | SLIDE 3
  • Who am I?  Maarten Balliauw  Antwerp, Belgium  www.realdolmen.com  Focus on web  ASP.NET MVC, Windows Azure, SignalR, ...  MVP Windows Azure & ASPInsider  http://blog.maartenballiauw.be  @maartenballiauw  Author: Pro NuGet - http://amzn.to/pronugetAPRIL 16, 2012 | SLIDE 4
  • Agenda  NuGet  Scenarios  Host your own NuGet repository  Continuous Package Integration Chickens?!  Abusing NuGet  NuGet Inception  ConclusionAPRIL 16, 2012 | SLIDE 5
  • NuGetAPRIL 16, 2012 | SLIDE 6
  • Welcome to Dependency Hell “A term for the frustration of software users who have installed software packages which have dependencies on specific versions of other software packages.” (Wikipedia)APRIL 16, 2012 | SLIDE 7
  • Cause and Effect  Reinventing the wheel  We don’t need that dependency  “If they can do it, we can do it, but better”  What happened to reuse of components?  Marketing-Driven Versioning  People are waiting for v2 to buy  Let’s call it v4 Platform Update SP3 November Edition KB2348063 RTW Refresh  We lost ownership of AssemblyVersion ?APRIL 16, 2012 | SLIDE 8
  • Package Management  NuGet to the Rescue! “NuGet is a Visual Studio extension that makes it easy to install and update open source libraries and tools in Visual Studio.”  Simple concept  Find Packages  (Re)Use Packages  Produce PackagesAPRIL 16, 2012 | SLIDE 9
  • Demo Finding & consuming a NuGet packageAPRIL 16, 2012 | SLIDE 10
  • Demo Creating & publishing a NuGet packageAPRIL 16, 2012 | SLIDE 11
  • Semantic Versioning  Think about your versioning! (semver.org) Major Breaking changes Minor Backwards compatible API additions/changes Patch Bugfixes not affecting the API  Always specify lowerbound  Use a version range (lowerbound + upperbound) when versioning of package you depend on is messed upAPRIL 16, 2012 | SLIDE 12
  • Hosting a repositoryAPRIL 16, 2012 | SLIDE 13
  • Hosting your own repository  NuGet = public feed  Privacy  Intellectual property  NuGet maintained by package authors  Author removes v1.0.45 and you depend on itAPRIL 16, 2012 | SLIDE 14
  • Solutions  Folder / File share  NuGet.Server package  NuGet Gallery (or Orchard Gallery)  MyGetAPRIL 16, 2012 | SLIDE 15
  • Demo NuGet.ServerAPRIL 16, 2012 | SLIDE 16
  • NuGet.Server limitations  Only 1 feed per installation  No UI  up to you to build it  No granular security  only 1 API-key for entire feed  Conclusion: requires you to develop if you want something more usefulAPRIL 16, 2012 | SLIDE 17
  • Meet MyGet  www.myget.org  NaaS  Register and off you go!  Supports Enterprise scenarios  Granular security  Package mirroring  ProxyingAPRIL 16, 2012 | SLIDE 18
  • Demo MyGetAPRIL 16, 2012 | SLIDE 19
  • Continuous Package IntegrationAPRIL 16, 2012 | SLIDE 20
  • Typical source control...  Contains /References (if you are lucky)  ...and also Project/_bin_deployable_assemblies  ...and also /References/old  ...and also /..././../.././References  Usually references GAC-ed assembliesAPRIL 16, 2012 | SLIDE 21
  • Dependencies  Software has dependencies. Deal with it.  But are those YOUR intellectual property?  YOUR reason to build software?  YOUR product?  No. They are dependencies. And they don’t belong in source control.APRIL 16, 2012 | SLIDE 22
  • Continuous Package Integration  Can I get rid of all these referenced assemblies duplicated all-over my source control system? Yes!  Do I need to install and maintain NuGet on all my build agents? No!APRIL 16, 2012 | SLIDE 23
  • Demo Package RestoreAPRIL 16, 2012 | SLIDE 24
  • 3rd parties don’t belong in your VCS  Replace them with NuGet packages  Do commit packagesrepositories.config file  Use Enable-PackageRestoreAPRIL 16, 2012 | SLIDE 25
  • Problem!  NuGet feed is subject to change...  PackageSource msbuild property to the rescue (NuGet.settings.targets in $(SolutionDir).nuget folder)  Now what...  Host your own feed and mirror packages  Or use MyGet for that APRIL 16, 2012 | SLIDE 26
  • Organize your chickens  Feed structuring  Scoped by quality: Build, QA, Production, …  Scoped by audience: public, restricted access  Other:  Scoped by product version, milestone…  Scoped by target platformAPRIL 16, 2012 | SLIDE 27
  • Guidance  Publishing a package brings great responsibility  Breaking changes in your packages should be versioned accordingly!  Consumers might choose to no longer consume any packages you publishedAPRIL 16, 2012 | SLIDE 28
  • Guidance  Package Integration ≠ Integration Testing  CI builds reflect output of source control input  Same input always produces same output  Do not auto-update packages during automated buildsAPRIL 16, 2012 | SLIDE 29
  • Abusing NuGetAPRIL 16, 2012 | SLIDE 30
  • Abusing NuGet? Change of perspective NuGet is a package manager NuGet is a protocol for distributing packagesAPRIL 16, 2012 | SLIDE 31
  • NuGet as a ProtocolAPRIL 16, 2012 | SLIDE 32
  • Chocolatey  NuGet  developer library packages  Chocolatey  applications and tools packager  “yum” or “apt-get” for Windows  www.chocolatey.orgAPRIL 16, 2012 | SLIDE 33
  • Demo ChocolateyAPRIL 16, 2012 | SLIDE 34
  • Automate deployments  Build results in .nupkg  Octopus deploys to its tentacles  Test tentacles  Staging tentacles  Production tentacles  www.octopusdeploy.comAPRIL 16, 2012 | SLIDE 35
  • APRIL 16, 2012 | SLIDE 36
  • Build Test Package Push Release / Publish Deploy Demo Continuous DeliveryAPRIL 16, 2012 | SLIDE 37
  • Conclusion Dependencies & people are chickens Deal with them! NuGet can help Set up your own NuGet repository Continuous package integration NuGet is a package manager NuGet is a protocolAPRIL 16, 2012 | SLIDE 38
