  4. 4. AGENDA  Chickens?  NuGet  Scenarios  Host your own NuGet repository  Continuous (Package) Integration  (Ab)using NuGet  ConclusionFEBRUARY 12, 2012 | SLIDE 4
  5. 5. Dependency Hell WELCOME TO DLL HELLFEBRUARY 12, 2012 | SLIDE 5
  6. 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.” Source: WikipediaFEBRUARY 12, 2012 | SLIDE 6
  7. 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 does the 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 ?FEBRUARY 12, 2012 | SLIDE 7
  8. 8. Using NuGet PACKAGE MANAGEMENTFEBRUARY 12, 2012 | SLIDE 8
  9. 9. 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.”FEBRUARY 12, 2012 | SLIDE 9
  10. 10. PACKAGE WHAT?  Package Management “…a collection of software tools to automate the process of installing, upgrading, configuring, and removing software packages…” Source: Wikipedia  Simple concept  Find Packages  (Re)Use Packages  Produce PackagesFEBRUARY 12, 2012 | SLIDE 10
  11. 11. GETTING STARTED  Tooling:  NuGet Package Manager (http://nuget.org)  NuGet Package Explorer (http://npe.codeplex.com)  Install-Package NuGetPowerTools  Install-Package NuGet.CommandLine  Guidance and documentation  http://docs.nuget.orgFEBRUARY 12, 2012 | SLIDE 11
  12. 12. CONSUMING PACKAGES  Simple as adding a referenceFEBRUARY 12, 2012 | SLIDE 12
  13. 13. ONE DIALOG TO RULE THEM ALL…  Install-Package  Update-Package  Uninstall-Package  Settings  Package Sources  Local (offline) Cache location  Also: Manage packages on solution level!  Right-click solution > Manage NuGet Packages…FEBRUARY 12, 2012 | SLIDE 13
  14. 14. NUGET PACKAGE MANAGER CONSOLE  PowerShell enabled!  Extensible!  Scaffolding, NuGetPowerTools, …  %UserProfile%DocumentsWindowsPowerShellNuGet_profile.ps1FEBRUARY 12, 2012 | SLIDE 14
  15. 15. CONFIGURABLE PACKAGE SOURCES  Configurable through…  NuGet Library Package Manager (VS add-in)  NuGet.config (in %APPDATA%RoamingNuGetNuGet.config)  NuGet.settings.targets (MSBUILD file part of NuGetPowerTools)FEBRUARY 12, 2012 | SLIDE 15
  16. 16. CREATING PACKAGES  What’s a package?  Just a zip-file containing:  … content and source code (to be injected into target project)  … PowerShell scripts and executables  … configuration file and source code transformations  http://docs.nuget.org/docs/creating-packages/Configuration-File- and-Source-Code-TransformationsFEBRUARY 12, 2012 | SLIDE 16
  17. 17. PACKAGE CONVENTIONS  Conventions  http://docs.nuget.org/docs/creating-packages/Package- Conventions  Folder structure  Tools (init.ps1, install.ps1, uninstall.ps1)  Content  Manifest (.nuspec file)  LibFEBRUARY 12, 2012 | SLIDE 17
  18. 18. NUGET MANIFEST SPECIFICATION  NuSpec manifest  XML file (with XSD available)  Package metadataFEBRUARY 12, 2012 | SLIDE 18
  19. 19. 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 upFEBRUARY 12, 2012 | SLIDE 19
  20. 20. ADVANCED USAGE SCENARIOS  Host your own NuGet repository  Continuous (Package) Integration  (Ab)using NuGetFEBRUARY 12, 2012 | SLIDE 20
  21. 21. Those chickens are mine! HOSTING YOUR OWN REPOSITORYFEBRUARY 12, 2012 | SLIDE 21
  22. 22. HOSTING YOUR OWN REPOSITORY  NuGet = public feed  Privacy  Intellectual property  NuGet maintained by package authors  Author removes v1.0.45 and you depend on itFEBRUARY 12, 2012 | SLIDE 22
  23. 23. SOLUTIONS  Folder / File share  Orchard Gallery (or NuGet Gallery)  NuGet.Server package  MyGetFEBRUARY 12, 2012 | SLIDE 23
  24. 24. Install-Package NuGet.Server NUGET.SERVER DEMOFEBRUARY 12, 2012 | SLIDE 24
  25. 25. 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 usefulFEBRUARY 12, 2012 | SLIDE 25
  26. 26. MEET MYGET  www.myget.org  NaaS  Register and off you go! (no dev)  Supports Enterprise scenarios  Granular security  Package mirroringFEBRUARY 12, 2012 | SLIDE 26
  27. 27. Log in to www.myget.org and get started MYGET DEMOFEBRUARY 12, 2012 | SLIDE 27
  28. 28. Fetch the chickens when you need them CONTINUOUS (PACKAGE) INTEGRATIONFEBRUARY 12, 2012 | SLIDE 28
  29. 29. 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 assembliesFEBRUARY 12, 2012 | SLIDE 29
  30. 30. 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.FEBRUARY 12, 2012 | SLIDE 30
  31. 31. 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!FEBRUARY 12, 2012 | SLIDE 31
  32. 32. Organize your build chickens! NUGETPOWERTOOLS DEMOFEBRUARY 12, 2012 | SLIDE 32
  33. 33. 3RD PARTIES DON’T BELONG IN YOUR SCM  Source control bloated with third-party binaries?  Replace them with NuGet packages  Commit packages.config/repositories.config files  Preferably not the packages  Use NuGetPowerTools  Enable-PackageRestoreFEBRUARY 12, 2012 | SLIDE 33
  34. 34. 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 third-party packages  Internal NuGet.Server  Network Share  Or use MyGet for that FEBRUARY 12, 2012 | SLIDE 34
  35. 35. 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 platformFEBRUARY 12, 2012 | SLIDE 35
  36. 36. (AB)USING NUGETFEBRUARY 12, 2012 | SLIDE 36
  37. 37. 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 publishedFEBRUARY 12, 2012 | SLIDE 37
  38. 38. 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 builds!FEBRUARY 12, 2012 | SLIDE 38
  39. 39. FEBRUARY 12, 2012 | SLIDE 39
  40. 40. (AB)USING NUGET?  Change of perspective NuGet as a package manager NuGet as a protocol for distributing packagesFEBRUARY 12, 2012 | SLIDE 40

  45. 45. NUGET COMMAND LINE PLUG-INS  Extend NuGet.exe  Custom Commands  How?  Build class library  Reference NuGet.exe  Inherit Command  Deploy your dll to %LocalAppData%NuGetCommandsFEBRUARY 12, 2012 | SLIDE 45
  46. 46. CHOCOLATEY  NuGet  developer library packages  Chocolatey  applications and tools packager  “yum” or “apt-get” for Windows  www.chocolatey.orgFEBRUARY 12, 2012 | SLIDE 46
  47. 47. NuGet desert CHOCOLATEY DEMOFEBRUARY 12, 2012 | SLIDE 47
  48. 48. ORCHARD / WEBMATRIX / …  NuGet not bound to VS  Orchard CMS: modules & themes  WebMatrix: install page helpers on the fly  Your app: offer plugins through a repoFEBRUARY 12, 2012 | SLIDE 48
  49. 49. CONCLUSIONFEBRUARY 12, 2012 | SLIDE 49
  50. 50. Conclusion• Dependencies & people are chickens Deal with them! NuGet can help• Set up your own NuGet repository for various reasons• Continuous package integration• NuGet is a package manager NuGet is a protocol www.visug.be
