The Pain of deploying Primary Interop Assemblies

Alright, first of all, what are Primary Interop Assemblies (PIAs), and why am I devoting an entire post to the pains caused by deploying these things? And secondly, how do they relate with what we’ve been talking about thus far? The answer to the second question is simple – we’ve been talking about COM Interop…


Channel 9: Dynamic in C#

Not too long ago, I did another Channel 9 video on Dynamic in C# with another compiler dev, Chris Burrows. In this video, we discuss the making of dynamic, as well as some of the drawbacks, design decisions, and philosophies behind the feature. Enjoy! link:


Com interop in C# 4.0: Indexed Properties

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…


COM Interop in C# 4.0

Wow, it’s been a while since I’ve last posted! Don’t worry, I’m still alive and kickin’, and we’re still workin’ on cool stuff for y’all to use. Let’s take a bit of a recap of how far we’ve come. We’ve chatted about dynamic binding in C# and how that all plays in with the DLR,…


Named and Optional arguments – ties and philosophies

Okay, my attempt at a clever title failed… Ties and Philosophers? I oughtta stick with technical writing. 🙂 We’re almost done with our chat about named and optional arguments. We’ve covered what the feature is about, and covered overload resolution in more detail. This time I want to do a quick wrap up of our…


Named arguments and overload resolution

Last time we talked about the basics of named arguments, optional arguments, and default values. From here on out, I’m just going to refer to the whole feature group as “named and optional arguments” – it’s just too much typing otherwise (we actually just refer to the feature as N&O internally). Let’s now dive a…


Named arguments, optional arguments, and default values

C# 4.0 introduces the concept of optional parameter values into the language. Now, this has been a controversial subject in the past, and we have had many requests for the feature, but have traditionally stayed away from it. So, why now? Well, before we get into the philosophy of why we decided to add it…


Dynamic in C# VII: Phantom Method Semantics

By now, my hope is that you all have a well-rounded view of dynamic. We started this series by introducing dynamic and talking about the basics of the feature, and have just finished talking about some of the feature’s limitations with the intent that giving both the good and the bad will help us gain…


Dynamic in C# VI: What dynamic does NOT do

As I mentioned last time, there are a few gotchas that we’ll need to look at in order to get a full understanding of the dynamic feature and its capabilities. Today we’ll take a look at some of those limitations. As we go along, I’ll try to shed some insights as to how the decision…


Dynamic in C# V: Indexers, Operators, and More!

Now that we’re all experts in how dynamic invocations work for regular method calls, lets extrapolate from our previous discussion about phantom methods a bit and take a look at how those basic concepts apply to other dynamic operations. Today we’ll just go through a laundry list of each type of operation, and throw in…
