So, I've recently changed jobs. Rather than working in .NET land, I've migrated over to Java land. But never fear! I'll continue to peer under the covers…

It's the bane of most programmers' lives - an unhandled exception causes your application or webapp to crash, an ugly dialog gets displayed to the user,…

Finally, in this series, I am going to cover some of the security issues that can trip you up when using sandboxed appdomains.

You write a security-related application that allows addins to be used. These addins (as dlls) can be downloaded from anywhere, and, if allowed to run…

So, how do you create partial-trust appdomains? Where do you come across them? There are two main situations in which your assembly runs as…

Portable Class Libraries were introduced with Visual Studio 2010 SP1 to aid writing libraries that could be used on many different platforms - the…

So, we've looked at how a dynamic call is represented in a compiled assembly, and how the dynamic lookup is performed at runtime. The last piece of the…

The DLR was introduced in .NET 4 to allow dynamic languages, like Python or Ruby, to run on the CLR. The DLR is also used by C# 4, released at the same…

I came across ThreadLocal<T> while I was researching ConcurrentBag. To look at it, it doesn't really make much sense. What's all those extra Cn classes…

So, day 1 of DevWeek. Lots and lots of Windows 8 and WinRT, as you would expect. The keynote had some actual content in it, fleshed out some of the…

Unlike the other concurrent collections, ConcurrentBag does not really have a non-concurrent analogy. As stated in the MSDN documentation, ConcurrentBag…

Using locks to implement a thread-safe collection is rather like using a sledgehammer - unsubtle, easy to understand, and tends to make any other tool…

The concurrent collections, located in the System.Collections.Concurrent namespace, were introduced in.NET 4 as thread-safe collections that could be used…

There's a new movement rumbling around Red Gate Towers - the Lean Startup. At its core is the idea that you don't have to be in a company with…

Although the collections classes introduced in .NET 2, 3.5 and 4 cover most scenarios, there are still some .NET 1 collections that don't have generic…

Apart from Dictionary<TKey, TValue>, there's two other dictionaries in the BCL - SortedDictionary<TKey, TValue> and SortedList<TKey, TValue>. On the face…

To many people, System.Collections.Generic.Dictionary<TKey,TValue> is just a useful collection. In this post, I'll be looking inside that collection and…

At TechEd this year, there's only a few sessions and expo booths aimed squarely at devs rather than sysadmins and DBAs, but one of the things I picked up…
