Lutz Roeder gets a blog.. Lutz is working a very cool product that uses some of my stuff and a lot of ChrisAn's stuff... He is also author of some very popular .NET tools ... Check it out..

We had a little thread internally on some good docs on how the GC works... These were the most popular whitepapers... http://msdn.microsoft.com/msdnmag/issues/1100/GCI/default.aspx http://msdn.microsoft.com/msdnmag/issues/1200/GCI2/

If you are serious about getting the best performance possible out of a managed app, you need to be using a profiler. The devs that designed and wrote the CLR still need to use a profiler to judge how to improve the performance of a managed app.....

Deepak Sharma asks : Where does String.Length == 0 stands in terms of memory efficiency compared to these two methods? Any ideas. I chatted with the Dev lead that owns String… here is his response: Actually, there is no memory effect here...

Q: Can you have memory leaks in managed code? If so, how can you catch them? A: (From the GC Architect) GC will typically reclaim objects at its own pace, based on balancing available memory and runtime overhead. If an assembly is terminated and...

I noticed someone hit my site from a google search on this topic. My guess is they didn't find out what they needed, so I thought i'd post a complete answer just in case someone else comes looking for it.. From Michael Fanning the Dev lead for FxCop...

Sonja just told me she had another episode posted... I have not watched it yet, but I am sure it is good. http://msdn.microsoft.com/msdntv/episode.aspx?xml=episodes/en/20030424NETFXSK/manifest.xml Platform Invoke Tips & Tricks: Memory Ownership...

Chris asks for a picture… finally got it … Long live command line apps!

I caught Jeffrey Richter and Chris Sells posing with their doppelgangers the other day on the 4th floor of building 42.

Rico is one of the smartest guys on the CLR team and he is super, super passionate about performance. He is looking at everyway possible to make managed code run faster... He just posted a great whitepaper on how the GC works and how to get the best...

Please welcome Adam Nathan . Adam is a test lead on the CLR team and knows everything there is to know about interop between managed code and unmanaged code. In fact he even wrote the book on the subject. I am sure you will find his blog a very useful...

Well, with a lead in like that I could not help but post. This sample comes from a f riend of mine working who is helping me with a little book project... using System; using System.Globalization; namespace Samples { public class DateTimeFormatInfoSample...

As David implies , there difference between String.Empty and “” are pretty small, but there is a difference. “” actually creates an object, it will likely be pulled out of the string intern pool, but still… while String.Empty creates no object… so...

I have not seen this be much of debate externally, but it has been pretty hotly debated internally. We just closed down on this guideline... As always, your comments are welcome: 2.3.4 Assembly/DLL Naming Guidelines An assembly is the...

Erica Wiechers from the .NET Show fame came by my office today and shot a short segment for MSDN TV about how the GC works and the Dispose pattern . I thought it went fairly well. I was impressed at how quick it went, it was so easy to get it scheduled...

I know, I know, you just got your hands on Everett , but I thought I’d start wetting your appetite for Whidbey (the next release of the . NET Framework and Tools)… As I see cool Whidbey demos I’ll let you know about them…. This one really brought...

I’ll be in North Carolina towards the end of May…. Anyone involved in a user group (or some such) that would like a presentation on what is new in the CLR or just want to chat about how the CLR could be better? I figure I have room for exactly...

I can’t believe it, just last week I was pulling great content from internal aliases and posting them here. Now Chris Brumme is actively blogging his OWN stuff and, even better, referring that same internal alias to his public blog. We are starting...

Yup Shawn has it pretty much right on . Both System.Enum and System.ValueType are themselves reference types. We added them to the system for two primary reasons: 1. We wanted to provide developers an easy way to group all ValueTypes and all...

More from the dev that owns the loader... If the exception message isn’t enough for you to determine what the problem is, try getting the Fusion log. It will describe the binding failure (if this is due to an assembly binding failure, instead...

More from inside the walls.. From the dev that owns the loader... AppDomain.Load() is only meant to be called on the current AppDomain (for use by Interop callers). If you call it on a different AppDomain, if the assembly successfully loads in the...

This comes up a lot on internal lists so I thought i'd share... from the FAQ: G et the hresult by calling System.Runtime.InteropServices.Marshal.GetHRForException() on the Exception object. If that info is not readily available, you may need to...

Chris is a senior architect on the CLR team... He literally knows how and why everyting in CLR works the way it does. I know he will have great stuff to share... Please take a look! http://blogs.gotdotnet.com/cbrumme/

I just had a little fun playing around with SOS today... Here is a bit of mail from a dev on the CLR debugger team that makes this magic happen. If you are running V1.1 then you can use the SOS.dll that is in the Framework\v1.1.4322 folder under...
