Demystifying WPF

Abstract

Everyone is a web guy these days. And web guys don't like WPF. That is fair enough, but I contend it is because the learning curve for 'decent WPF' is much steeper than 'decent web' pauses for heckles, and this is due to the fact that ASP.net MVC now has so much functionality supplied right out of the box - no one needs to ask 'how should I be doing X these days?' for even moderately complex applications.

Here we will look at how to get started building a truly modern application with WPF; which frameworks and packages provide us with the most bang per buck right out of the gate; and how we can deal simply and cleanly with basic, critical functionality such as data validation, command execution and messaging.

We will then wrap it all up in a neat little Visual Studio template so that we don't need to reinvent the wheel each time we go File > New > Project > WPF Application.

X-ray Goggles

Abstract

Are you a product owner? Do you have a product out in the wild, but can't answer who is using what features? Are you a developer? Are you currently developing a product but can't tell your product owner or boss which bugs are occurring out in the wild most frequently? Do you dabble in support? Can you provide the development team with deep information regarding defects your customers are screaming at you about? When someone says to you 'it's slow', and you of course respond with 'which part?' and the unquenchable fountain of insight that is your product owner / tester / end user says 'the whole thing' - do you have any data you can point to?

You need to know what is going on in your products from day one, and finding out shouldn't involve pushing out new builds to add more Trace.WriteLines / StopWatch.StartNews or logging onto various azure cloud service instances to pore over text log files. Lets take a look at some of the tooling and services available to us today and build a

The Seven Year Itch

Abstract

In this session Andrew will refactor an existing Angular web application to React, and then measure the outcomes to validate whether React is a viable alternative to Angular.

With Angular nearing its seventh year of life and approaching obselecense, is it time we entertain the idea of seeing new front-end frameworks? Andrew's inspiration for this framework promiscuity came from a conversation he had with colleagues one day around getting Angular to perform a particular task. The outcome of the particular conversation was much introspection as to why we put ourselves through such pain when developing software - so as any good developer does, Andrew is going to see what we can do to make the pain go away.

	:: To see what certificates you currently have on your PC, open MMC (Run->mmc.exe), click "File->Add/Remove Snap-in", select Certificates from the left list, click "Add". Select "My user account", which will mean the snapin will show certificates that are stored specifically for your Windows user account. Select Certificates from the list again and "Add" it, then this time select "Computer account". This snapin will show certificates belonging to the machine specifically, and will apply across all accounts. Press Finish, then OK. I suggest you Save this MMC arrangement, so you can get back to it more easily in the future (File->Save).

	:: Expand "Certificates (Local Computer)\Trusted Root Certification Authorities\Certificates". This folder shows you all the Certificate Authorities that your computer trusts.

	:: So now we need to create our own Certificate Authority certificate. Open the Visual Studio
