Agenda NuGet New Problems Solutions! The NuGet Ecosystem Conclusion

NuGet

Before NuGet: third-party and OSS Everything points towards Microsoft Only for those who search Google, Bing, CodePlex, GitHub, …

False competition Microsoft things either bundled or via a neat installer

Hard to integrate OSS Compile? Find right version? Find right dependencies?

Before NuGet: sharing own code Shared code in source control Or compiled code in separate assembly Separate assembly on a network share or in source control No versioning on the assembly file Update nightmare (“big solutions”)

NuGet!

With NuGet: third-party and OSS One repository: NuGet.org OSS and Microsoft provided libraries mixed Dependencies, Configuration changes, Versioning

With NuGet: sharing own code Create a NuGet package Specify dependencies, enforce versioning Consuming project: specify version Updating is a joy

Windows Phone Exampleshttps://www.nuget.org/packages?q=windowsphone

Windows 8Exampleshttps://www.nuget.org/packages?q=windows8

Let’s install one!And look at some internals

New Problems

Versioning U depends on T Y depends on T Let’s upgrade T!

One repository It’s a bit of an App Store… Fine for OSS, but what with my own frameworks?

Overconsumption That’s a cool library! And that’s a cool library! And that one too! Ooh, another one! How to limit choice?

Licensing Developers on a roll don’t care! But you may do… How to limit choice?

Solutions!

Enforce Explicit Semantic Versioning www.semver.org

Major Breaking changes

Minor Backwards compatible API additions/changes

Patch Bugfixes not affecting the API <dependency id="ExamplePackage" version="1.3.2" />

1.0  = 1.0 ≤ x(,1.0]  = x ≤ 1.0(,1.0)  = x < 1.0[1.0] = x == 1.0(1.0) = invalid(1.0,) = 1.0 < x(1.0,2.0) = 1.0 < x < 2.0[1.0,2.0] = 1.0 ≤ x ≤ 2.0empty = latest version

Recommendation Engine http://concierge.nuget.org Upload packages.config Find recommendations

Hosting Your Own Repository Folder / File share NuGet.Server package NuGet Gallery – www.github.com/nuget/nugetgallery MyGet – www.myget.org

Create your own feed! Have a copy of your dependencies! Manage approved packages Manage licenses Host your own packages Private feeds Use it for staging packages

One more recommendation… Don’t just update Not everyone respects SemVer…

Don’t autoupdate during builds Continuous Integration: Same Input = Same Output
