My Impressions from Build 2015

Thursday, May 7, 2015

Last week I attended Microsoft's Build conference at San-Francisco along with my colleagues. Build is Microsoft's prime developer conference, and as such it is packed with technical content relating to software development on top of Microsoft's various platforms - from Band, to Xbox, to PC to Azure. In this post I'll try to summarize my key observations and feelings following my attendance. The New Microsoft This started already at the previous Build last year. Following Steven Sinofsky's departure and the appointment of Satya Nadella as CEO, Microsoft has started being a more open company oriented towards its consumers and developers. One of...

Released: Code Contracts VS2012 Editor Extensions

Sunday, March 24, 2013

Code Contracts is an experimental project from Microsoft Research which provides a language-agnostic way to express coding assumptions in .NET programs, thus allowing for improved testability, static verification at compile time and automatic API documentation. If you participated in my session about Code Contracts last week, then you already know that. At my session, I said that Microsoft has not yet released the Code Contracts Editor Extensions for VS2012. Well that, my friends, has changed… Microsoft has just released the Code Contracts Editor Extensions for VS2012! This extension allows you display Code Contracts in code, Intellisense and...

Upcoming Event: Code Contracts Lecture

Monday, March 11, 2013

If you ever used a 3rd party API, you surely know the importance of proper documentation - Can this method return "null"? Do I have to check this return value? What are the valid values of this argument? You also probably know that the only way to discover if your assumptions are correct is to execute the code and pray that exceptions won't be flying around. There must be a better way! Enter "Code Contracts". Code Contracts is an experimental project from Microsoft Research which provides a language-agnostic way to express coding assumptions in .NET programs, thus allowing...

Upcoming Event: WF 4.5 Lecture

Tuesday, March 5, 2013

Windows Workflow Foundation (WF) is Microsoft's .NET implementation of a Workflow authoring and hosting environment. With WF 4.5 developers can easily author workflows using the Visual-Studio built-in WF designer, host them in multiple application environments using the provided runtime engine and even expose them as services for the outside world to consume. Oh, and it's totally free… On Wednesday, March 20th 2013, I’ll give a presentation on WF 4.5 at the Israeli .NET User Group (Microsoft Israel, Ra’anana). In this session we'll focus on the cool new features which version 4.5 brings to the table with demonstrations including...

Accessing the AggregateException with await

Monday, December 31, 2012

The await keyword is a new keyword in C# 5.0 which, in tandem with async keyword, allows us to easily author methods which execute asynchronously in regards to the calling code. In previous posts I’ve shown certain issues you should look out for when using these keyword. In this post we’ll look at another issue with the await keyword – how to access the AggregateException. await Only Throws One Exception As we saw in a previous post, await (unlike Task.Wait()) does not wrap a thrown exception in an AggregateException and instead just re-throws the exception thrown within...

Task.Wait() vs. await

Sunday, December 23, 2012

The await keyword is a new keyword in C# 5.0 which, in tandem with async keyword, allows us to easily author methods which execute asynchronously in regards to the calling code. In a previous post I’ve shown a certain issue you should look out for when using the async keyword. In this post we’ll check a similar issue with the await keyword. The await Trap Let’s remember our test code from the previous post: class AsyncClass { public void Process(string s) { if (s...
