Chained null checks and the Maybe monad(devtalk.net)

submitted by dmitri(408) 1 year, 8 months ago

A great many programmers have met a situation where, while accessing a nested object property (e.g., person.Address.PostCode), they have to do several null checks. This requirement frequently pops up in XML parsing where missing elements and attributes can return null when you attempt to access them (and subsequently trying to access Value throws a NullReferenceException). In this article, I’ll show how a take on the Maybe monad in C#, coupled with use of extension methods, can be used to improve readability. read more...

Com interop in C# 4.0: Indexed Properties (blogs.msdn.com)

submitted by samng(135) 2 years, 6 months ago

One of the things I love about my job is that I get to make people happy. How do I do that? By giving them what they want of course! One of the things I don’t like so much about my job is going back on a decision that we made before, and having to revert some of the behavior. Well, we’ve been talking about COM interop in C# 4.0, and are now in the thick of things. Today we’ll chat about a feature which many people have asked for in the past, but we’ve stayed away from until now – Indexed Properties. read more...

Indexed Properties in C# 4.0(blogs.msdn.com)

submitted by KirillOsenkov(570) 2 years, 7 months ago

In C# 4.0 you can call parameterized properties that are declared in other languages (VB, COM, C++, etc) using the indexer syntax, for instance instead of excel.get_Range("a") you can now write excel.Range["a"]. You still can’t declare your own indexed properties from C#. The feature is immediately available in Visual Studio 2010 Beta 2 for your indexing pleasure. read more...

Booting from a VHD(blogs.msdn.com)

submitted by CharlieCalvert(7875) 2 years, 8 months ago

Hosting an OS in a virtual machine can be very useful for developers, but sometimes one pays a price in terms of performance. In Windows 7 developers can get improved performance in virtual machines by native booting a VHD. First create a Virtual PC that hosts Windows 7, then restart your computer, and finally boot directly into the VHD that contains the Windows 7 OS. When you native boot a VHD your virtual machine runs very close to the metal; performance is greatly enhanced and you have much better support for OS features that may not be available inside a standard Virtual PC. read more...

Welcome to the fifty-first edition of Community Convergence. In this post I’m simply going to highlight some of the great blogging activity produced by our team in recent weeks. Eric Lippert has been wonderfully productive. I’m beginning to wonder if we shouldn’t simply dedicate an entire section of the Internet to his work. I’ve also included a few pointers to the work of our friends in the F# world; both Luke and Luca played major roles in the C# world for many years, and it is fun to track what they are doing with F#. read more...
