BOOK: Microsoft AJAX Library Essentials

This is another one of those "Sniper Topics" that I like, again from PAKT Publishing. Microsoft AJAX Library Essentials: Client-side ASP.NET AJAX 1.0 Explained: Cristian Darie,Bogdan Brinzarea: Books ISBN : 1847190987 ISBN-13 : 9781847190987 Approximately 280 pages of drill down on Object Oriented Client Side development in JavaScript using the Microsoft AJAX Client Libraries. Not only does this text enumerates the namespaces in the Microsoft AJAX Client Libraries, and provide good coverage of the Client Component Framework, but it teaches all the "whys" along with the "How Tos". If your building AJAX applications and Microsoft's AJAX technology is at the center of your work then this book is a "must read"...

ASP.NET Tips: Looking at the finalization queue

So in a previous post, we talked about Understanding when to use a Finalizer in your .NET class so now lets take a look at what the Finalize queue looks like and how to tell if things are bad. The command we use is !finalizequeue in sos: 0:010> !finalizequeue...

Setting breakpoints in .net code using !bpmd

From time to time I get questions like "our process spawns a lot of threads, how do we know who created them?" or "can I tell how many times we call this method?". You can answer both of these questions by setting breakpoints, and below is a simple sample of how this is done in windbg with sos... My demo application (MyApplication.exe) has a class MyThreadClass that has a method CreateAThread, this creates a thread and starts running some method on that thread. What I am going to show here is how you can set a breakpoint when a thread is started to identify that the method CreateAThread started it, and automate it so that you don't have to click go after each time you hit the breakpoint... 1. Attach to the process with...

Managed Extensibility Framework

Krzysztof recently announced on his blog that we have begun working on an extensibility framework for .NET..   We will blog more details about MEF in the upcoming months, but here are some early details (subject to changes, of course): MEF is a set of features referred in the academic community and in the industry as a Naming and Activation Service (returns an object given a “name”), Dependency Injection (DI) framework, and a Structural Type System (duck typing). These technologies (and other like System.AddIn) together are intended to enable the world of what we call Open and Dynamic Applications, i.e. make it easier and cheaper to build extensible applications and extensions. [....] And finally here is some code showing basic...

Workaround: Empty Design View for User Controls

I've noticed quite a few people run into the issue "Why is design mode empty for my web user control (ASCX)?". It's not obvious what might be causing this bug, so I thought I'd offer an explanation and a couple workarounds. Problem You have a user control that has a "link" tag to an external style sheet or a "style" tag with local styles at the top of the page. Immediately below the style, you have a web control (such as a Wizard control) that contains the bulk of the content. You attempt to edit this user control in design view and all you see is an empty page. Here's a trivial example: Explanation Design view was originally created to handle full HTML pages where the "body" and "head"...
