Asynchronous programming can be very difficult, and if done incorrectly it can cause devastating results in your applications!In this talk I introduce asynchronous programming in .NET and talk about a few gotchas that will be handy along the way. I'd also like to take this opportunity to announce that I'm working on my next Pluralsight course that will talk about Asynchronous Programming in .NET. It is definitely an important subject and I hope you'll enjoy both my coming course, and the below presentation. [...]

Over the past year I've done a few talks on C# 6.0 and the changes that we can expect from the next version of C#. Interestingly enough, each time I've done this talk a bunch of things have changed. Features have been added, features have been put on-hold and most importantly more people have joined the discussions on Github.
I was invited to speak at the Sydney and Canberra .NET User Groups where I talked about how C# is truly a relevant programming language of the future. It's time to embrace it! [...]

Yesterday I was notified on Twitter that the RSS feed for my blog included draft posts. Which is not really ideal since it will contain articles that aren't really ready. I have previously written about how I moved to Sandra.Snow from Wordpress and how much I really enjoy this transition. One of the biggest benefits is that it is open source, this means fixing this bug was rather easy and quick.
Albeit the fix might have been easy and quick, I did run in to some issues with my automatic deployment. Every time I check something in to the git repository, Azure will notice this and start deploying my website. Little did I know that there was another bug, unrelated to the RSS feed getting my drafts, in my deployment script. Luckily for me, I got Microsoft Azure Traffic Manager running on-top of my blog, which means that I load balance between different zones.
The load balancer is configured to run in performance mode so that visitors in US are transferred to the US West location. Meanwhile, EU visitors are transitioned to the EU location and Asia to the Southeast Asia location.
To avoid down-time, I had two options when fiddling around with the fix for the bug.
- Clone the Website in one of the locations and setup a staging like environment
- Disable one of the locations in the load balancer and use that as a staging environment
Obviously the second option would be cheaper, but it does come at a price: users from that location will experience longer load times. [...]

As of next week I'm joining Invoice2go as a Senior Software Engineer! For the past 1 year and 8 months I've worked with some of the best people in my career at Readify. I'm truly grateful for the opportunity to move to Australia and work with these amazing people!
For the past 10 years I've worked as a consultant in some way or another and it's been a great journey! I'm super excited to step into a product company and face some really exciting challenges.
Working for Readify has given me a lot of confidence and opportunities to work on myself, which I am eternally grateful for. When moving to Australia I had never done any public speaking in English and it's been exciting to get better and better at this over time. Joining Invoice2go means I will still be living and working in Australia, which is great, the development community here is so friendly and exciting!
I would really like to thank everyone that has attended my sessions, watched my courses, read my book or visited this blog; you are all the reason I love doing what I do. Without your support, I would never have moved to Australia and I would never have had the opportunity to work with these great companies!
My adventure at Invoice2Go starts next week and I am super excited!

Asynchronous programming have been around for quite some time. Even so it is becoming more and more important! It is surely not an easy topic to master, but in this 1.5 hour session I will do my best to explain the fundamentals to Asynchronous Programming.
After watching this session, I hope that you will have a good understanding how to use asynchronous operations in your code. Be it a WPF, Windows Forms, Xamarin.iOS, Xamarin.Android, ASP.NET or other .NET application! We will of course look at the most common reasons for locking and killing your application.
Slides available below on Slideshare
Let me know if this was helpful to you and if you have questions about asynchronous programming!

Not too long ago I noticed a rather interesting question on JabbR that caught my attention:
When is 1 not equal to 1? asked the developer. Loving to solve problems and help others, I started questioning my fellow developer about the details of the problem. The first thought that popped up in my head take us back to my university days when first hearing about
NaN (Not a Number), by definition
NaN != NaN.
To my surprise the data type was not of a type where
NaN is applicable; [...]

The next version of C# brings a lot of sugar to the table, which we have looked at a few times already. Although, I think it will be interesting to look into a few of the features in more detail and of course look at what tools like reflector says about the code generated. To start this off I want to look at null propagation. This is one of my favourite language features in the upcoming version of C#. I think, and I hope, that this will change the amount of Null Reference Exceptions that we experience in our applications.
Let us start by just looking at the operator itself, it's simple and elegant. The null propagation operator looks like this:

It feels like it was just yesterday that we moved to Australia, even though it is almost 1.5 years ago. It does feel like time goes faster when you're having a lot of fun, and I sure have had in 2014! I'm truly humbled and honoured to be awarded with the Microsoft MVP Award for a third year in a row. I'm really proud to be a .NET MVP!
I have every single one of you to thank for it, without you reading this blog, watching my videos, attending my presentations it wouldn't have been possible. It truly re-fuels me standing in front of a crowd sharing my knowledge, writing about new(or old) things that excites me or recording courses that will help you advance in your career. Speaking of career progression, I'm very happy to have been promoted to Senior Consultant at Readify. Not a single day goes by that I don't learn something new and I truly love it! [...]

Azure Mobile Services As We Know It
If you, as many others, look for an easy way to create a scalable and reliable backend, Azure Mobile Services is a viable option. Up until today, we have had the capabilities of defining the backend in Mobile Services using NodeJS. Even if you have used Mobile Services though, you might not have had to bother with the NodeJS parts because out of the box you have a dynamic data schema that adapts with the models you define.
On-top of allowing you to easily define what the data looks like, you have been able to use NodeJS when inserting, updating or deleting data to for instance make sure that a user is authenticated. The word "mobile" comes nicely into play as developers of Mobile applications we do not want to focus too much on where we store data and how it is done; we want as low friction as possible! Thus having an extremely easy way to define, extend and scale a backend is highly valuable.

Working in an agile environment
While working in a high paced and agile environment, building block by block to reach the ultimate minimal viable product, stakeholders will most definitely ask more than once if they can see what you have thus far.
Agile, Scrum, continuous delivery and testing are not new concepts or buzz-words. Although they have all been around for a while they are still something well worth talking about and working on improving in your team.
Over the years I have seen countless of products being worked on where there has been no real definition of, or well-thought through direction to get to, a minimal viable product. The main problem I see derives from the customer not being able to define a subset of features that are good enough for a first product release. If we put ourselves in the shoes of a customer, we might as well have been a customer or will be in the future, imagine having a vision of a great product and someone telling you to cut it in half and choose which side you like the most. It's difficult, right?

A bit over a year ago I wrote and talked about Roslyn a fair bit, a lot has happened in this last year both in terms of the progression of the C# language and the compiler platform itself. Most notably is probably the decision to make the compiler platform open source which happened earlier this year. With the decision to open source the compiler platform, it meant that the community could take part of what is the next version of the languages, what the compilers looks like under the hood and most interesting of them all: the decision making behind language features and directions of the project.
I will not go into detail on the language features of C# 6.0 as there is an article published by me in the DNC Magazine on this. Instead we will take a look at how we can use what is available to us today. [...]

I was again invited to write an article for DNC Magazine, this time on the changes that we will see in the upcoming language changes coming in C# 6.0.
We will not necessarily see new keywords in C# vNext, but we will see semantic differences that will make it easier for developers to avoid boilerplate code.
Some of these introduced semantic differences are much awaited and some of them are solving thinner edge cases; they are all very welcomed by the community! As the next version of the compiler is still under development, some of the language features may be taken out, some may be added and some may be delayed to the version after vNext.
The evolution of C# is a proof that the language lives, people are using it and it is here to stay.
Read the entire article in the DNC Magazine!

Rather frequently I get questions from friends, family and strangers asking me about what it's like to work as a software engineer. We've got a good reputation that we are well paid and have fun at work, at least that is what I've noticed people thinking about this occupation. It's not like we're paid as much as movie stars, even though some of us pretend that we are stars, but it still attracts people because of the wages and its reputation. [...]

As I'm down in Melbourne for a Readify Dev Breakfast Xamarin talk, why not visit the local .NET User Group and have a chat about Universal Apps for Windows and Windows Phone?
With the new possibilities of sharing code between our Windows and Windows Phone applications, there is no longer a reason not to target all the platforms! We are looking at what this new development model looks like, how to make our first universal app and or course, how to communicate with the cloud! [...]

This is truly an extremely exciting time, Microsoft is Open Sourcing the C# Compiler (Roslyn). Even without being open source, the new C# (and VB) compiler have had some proven potential. We have seen some exciting things such as semantic merge and powerful plugins for Visual Studio.
Now that the source is out there and they are accepting contributions - where do you think this will end? Personally, I cannot even imagine what the community will come up with.
C# Compiler Source Code Available Here. [...]

In this breakfast event that I spoke at which my employer Readify organizes, I talked about Parallel and Asynchronous applications. The idea here is to talk about what makes an application fast and reliable. Then we talk about different concepts and how to apply these in small isolated code snippets to make use of some really powerful stuff we have to our disposal.
This talk is aimed towards C# developers, but the parallel and asynchronous information applies to more than just the .NET family. [...]
