Continuous Integration in .NET
Every Commit should build the mainline on
integration machine
Keep the Build fast
Everyone can see what's happening

Continuous Delivery
Building, Testing
releasing
faster
frequently
Continuous Delivery: Reliable Software
Releases through Build, Test, and
Deployment Automation
The process for releasing/deploying software
MUST be repeatable and reliable.
Automate everything!
Done means “released”.
If something difficult or painful, do it more
often.
Deployment Pipeline models the part of your project’s
value stream that goes from check-in to release, and then
to automate it.

Methodology
Test In Production (TiP)
• Continuously and extensively Monitoring and experimental our service in
production
Continuous Deployment
• Frequent deployments of small changes to production environment (starting
with weekly releases)
Continuous Integration
• Minimize the gap between code development and deployment readiness
Pushing Quality Upstream
• Efficient processes to reduce the cost and gaps between product and quality
development
Continuous Improvement
• Constant observation, measurement and feedback on processes ,systems
and cost
