Editor's Notes

  • Maarten
  • 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 
