DESCRIPTION
NuGet quickly became a very popular package management solution for .NET and has been around for some time now. The introduction of a central package repository and the integrated NuGet tooling suddenly made it a whole lot easier to improve certain ALM processes, proof of which can be found into the increasing rate at which many packages make it to the NuGet Gallery. At the same time, most businesses are struggling how to take optimal benefit from this while trying to avoid a situation commonly known as “dependency hell”. In addition, most are not anticipating or designing for failure by depending directly, which became painfully clear during a recent downtime of the NuGet Gallery. This session will provide you with guidance on how you can use both NuGet and TFS11 to take your development environment to the next level.

AGENDA
Continuous Integration Room for Improvement
Dealing with dependencies Versioning VCS issues Debugging
Package Management One step closer to Continuous Delivery?
1 + 1 = Optimize for Happiness
APRIL 12, 2023 | SLIDE 5
CONTINUOUS INTEGRATION
Do you speak it?
APRIL 12, 2023 | SLIDE 6
DISCLAIMER
Not saying “my way” must be “your way”
Non-optimal doesn’t mean wrong
Pointing out opportunities and alternatives
APRIL 12, 2023 | SLIDE 7
CONTINUOUS INTEGRATION
Team members integrate their work frequently Each integration is verified by an automated
build (including tests)
Goal: Detect integration errors As quickly as possible!
Why? Reduce risks Deployable software at any time

(OFTEN) NON-OPTIMAL SETUP
Most commonly encountered approach to CI
Automated Build triggered by VCS
All tests run every single time
Eventually someone looks at the CI outcome

WHAT IF…
… compilation fails? Changes already in VCS! Entire team affected
… a test fails? Same story!
… no one noticed the CI failed? Kittens die!

DEALING WITH DEPENDENCIES
APRIL 12, 2023 | SLIDE 19
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.”
APRIL 12, 2023 | SLIDE 20
REACTIONS
Reinventing the wheel We don’t need that dependency “If they can do it, we can do it, but better”
Marketing-driven versioning People are waiting for v2 to buy Let’s call it v7 Platform Update SP3 November Edition
KB2348063 RTW Refresh
What happened to reuse of components? We lost ownership of AssemblyVersion ?
APRIL 12, 2023 | SLIDE 21
CAUSE AND EFFECT
Reference-by-source• “Needed for debugging”
syndrome• Found a bug and fixed it• Upgrade path: merges!
Reference-by-release• Use symbols for debugging• Report/Fix the bug and
submit a pull request• Clean upgrade path

PACKAGEMANAGEMENT

NUGET
NuGet Gallery 5000+ unique packages Within “2 clicks or 1 command” reach inside Visual
Studio
NuGet improved Discoverability Upgrade experience Reuse of software Reference-by-release + symbols for everyone
NuGet provides opportunities Dependency management Reach, discoverability & visibility of own packages
APRIL 12, 2023 | SLIDE 24
VERSIONING
NuGet supports Semantic Versioning http://www.semver.org
Prerelease Tags: Alpha, Beta, RC, … (e.g. v1.0.0-RC) Note: precedence in alphabetic order!
Major Breaking changes
Minor Backwards compatible API additions/changes
Patch Bugfixes not affecting the API
APRIL 12, 2023 | SLIDE 25
NUGET SUPPORTS SEMANTIC VERSIONING
But not entirely… NuGet doesn’t support 4th version number (build) for
prereleases 1.0.0-RC.32190
Caution: pick a scheme! Major.Minor.Patch[-Prerelease] Major.Minor.Patch[.Build]
Workaround: push CI packages to another feed, e.g. MyGet.org mark CI packages as prerelease when pushing to NuGet.org
– Remove Build number– Append Prerelease tag
APRIL 12, 2023 | SLIDE 26
DEPENDENCIES VS VCS
In TFS terms: Source Control Today often contains
Documents Binaries Tools Scripts Sources
Struggling with binary diffs Merge conflicts
Repository size
APRIL 12, 2023 | SLIDE 27
PACKAGE REPOSITORY
NuGet Package Repository Package Restore feature
Opportunity Get rid of binaries in VCS Decrease binary diff issues & merge conflicts Decrease VCS repository size Manage dependencies centrally Fine-grained packages = fine-grained dependencies
APRIL 12, 2023 | SLIDE 28
IN OR OUT?
Your choice Have a strategy!
No-Commit? What if the package source goes down? What if a package got removed from the repository? Mirroring
APRIL 12, 2023 | SLIDE 29
SOLUTION SETUP
