9. Cadence
VS & TFS: Cumulative updates that ship ~3 months
ASP.NET & EF : Using Nuget to update more often
Since August 2012
10 updates from various teams that update VS

10. Cadence
Lots of new functionality in the Gallery
Since August 2012
Almost 20 extensions released by Microsoft
That means a new extension almost every 13 days!
Excluding updates!

11. My favourite mini tricks
Upgrading to VS 2012
New culture options & how Windows 8 will break your
apps
How CallerMemberName will make your MVVM better

12. My favourite mini tricks

13. Did you see what Microsoft changed in Win8?

14. Impact of that little change?
Office: I am learning a whole new set of pain
.NET: .Format, .ToString & .Parse
SharePoint: Built on .NET – impacted by this
Your existing data in a database

15. Review: My favourite mini tricks
VS 2012 upgrading is a much lower risk
Culture can be globally controlled
CallerMemberName = awesome

16. Workflow Foundation
Look at the much improved designer
We finally get C# support
Review of workflow persistence, good, bad & what fixes
it!

17. Workflow Foundation

18. Workflow Persistence: What is it?
Code
Wait for
Timer
later time
Crashes Admin
Database
Server

19. Workflow Persistence: Problem?
Code
Wait for
Timer
later time
Crashes Admin
Database
Server

20. Workflow Persistence in .NET 4.5
Workflow 4.5 has versioning
Side by side versioning
Dynamic update versioning

21. Review: Workflow Foundation
Designer has been vastly improved
C# support
Workflow persistence

22. Async
Look at async & await modifiers
See how to use your existing Task skills
New TPL features: WhenAll, WhenAny, Delay
Review how the framework is leveraging this

23. Async

24. Review: Async
async & await modifiers give us syntactic sugar
Build using the Tasks – so your current Task skills carry
over
New TPL features: WhenAll, WhenAny, Delay
Plenty of .NET API’s offering async modes

25. Review
History & Trajectory – expect more features more often
VS Update is low risk
Mini tricks: CallerMemberName & Culture
Workflow development & versioning
Async: another tool in your concurrency tool belt
