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!

My favourite mini tricks

Upgrading to VS 2012

New culture options & how Windows 8 will break your appsHow CallerMemberName will make your MVVM better

My favourite mini tricks

Did you see what Microsoft changed in Win8?

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

Review: My favourite mini tricks

VS 2012 upgrading is a much lower risk

Culture can be globally controlled

CallerMemberName = awesome

Workflow Foundation

Look at the much improved designer

We finally get C# support

Review of workflow persistence, good, bad & what fixes it!

Workflow Persistence in .NET 4.5

Workflow 4.5 has versioning

Side by side versioning

Dynamic update versioning

Review: Workflow Foundation

Designer has been vastly improved

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

Async

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

Review

History & Trajectory – expect more features more often

VS Update is low risk
