13. Challenges with current code base
5/15/2018
Challenges with current code base
Long history going back to the WinFS days
Extensive use of older APIs and design patterns
Heavy use of APIs not available on all platforms
Lots of seldom used code/features
Monolithic implementation
Unintuitive behaviors woven throughout code base
Not optimized for density/devices
High memory footprint
Tight coupling to relational concepts

5/15/2018
What we are doing
Lightweight, extensible version of EF
Just the commonly used features (and many new features)
Built using modern design patterns
DbContext and code-based modelling only
Not a micro-O/RM
Still supports LINQ, change tracking, unit of work, etc.
Support relational & non-relational stores
Not a high level abstraction over all data stores
Provide high level services that are useful on all/most stores
Non-common concerns handled by provider extensions

15. Design principles Keep EF6 patterns Pay per play Extensible
5/15/2018
Design principles
Keep EF6 patterns
Only break from existing patterns where there is good reason
Pay per play
Simpler apps will require fewer resources
Low memory footprint
Extensible
Simple high level API over building blocks
Easy to replace/extend individual building blocks as needed
Sensible defaults, less magic
Only support magic where it supports long term success

16. What about EF6 apps? You don’t have to upgrade
5/15/2018
What about EF6 apps?
You don’t have to upgrade
EF6 is still supported
Updates to EF6 will continue (we’ve done EF6.1 and EF6.1.1 in parallel with EF7)
Not all EF6 features will be in 7.0.0
We don’t expect everyone to be able to upgrade immediately
Upgrade is a key scenario
Same concepts, same patterns
Some code changes will be needed
