CLR Profiler: No Code Can Hide from the Profiling API in the .NET Framework 2.0

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

The common language runtime (CLR) profiling API makes available information about the application domains, assemblies, and classes that are loaded and used in a process, just-in-time (JIT) compiler notifications, memory usage tracking, tracing of events, exception tracking, managed to unmanaged code transitions, and the state of the runtime. And if that weren't enough, you will find a nicely enhanced profiling API in the .NET Framework 2.0. Find out what's coming up in this next version.

.NET Internals: Rewrite MSIL Code on the Fly with the .NET Framework Profiling API


In this article, the author shows how to dynamically rewrite Microsoft Intermediate Language code on the fly using the Profiling API of the CLR. Unlike approaches based on Reflection.Emit, this scheme works with the existing assemblies and doesn't require the creation of proxy or dynamic assemblies. The need for IL code rewriting emerges when you want to make your changes transparent to the client and preserve the identity of classes. This technique can be used for creation of interceptors, pre- and post-processing method calls, and code instrumentation and verification.

Bar Code Scanners with the .NET Compact Framework

Summary: Learn how to make your applications use bar code scanners in a generic way-ndependent of the specific bar code scanners that are used on different devices. Using the design patterns Façade and Factory, the implementation not only supports multiple bar code scanners, but it also makes it easy to add support for other bar code scanners. After a brief discussion about bar code scanners and the bar code scanner pattern, a download code sample, written in C#, demonstrates the use of the pattern and technologies.

Are You in the Know?: Find Out What's New with Code Access Security in the .NET Framework 2.0


Unlike role-based security measures, code access security is not based on user identity. Instead, it is based on the identity of the code that is running, including information such as where the code came from. Here Mike Downen discusses the role of code access security (CAS) in .NET and outlines some key new features and changes in CAS for the .NET Framework 2.0.

High Availability: Keep Your Code Running with the Reliability Features of the .NET Framework


Reliability requires the capacity to execute a sequence of operations in a deterministic way, even under exceptional conditions. This allows you to ensure that resources are not leaked and that you can maintain state consistency without relying on application domain unloading (or worse, process restarts) to fix any corrupted state. Unfortunately, in the.NET Framework, not all exceptions are deterministic and synchronous, which makes it difficult to write code that is always deterministic in its ability to execute a predetermined sequence of operations. In this article Stephen Toub will show you why, and explore features of the .NET Framework 2.0 that help you to mitigate these situations and write more reliable code.

C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework


When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.

The Weekly Source Code 56 - Visual Studio 2010 and .NET Framework 4 Training Kit - Code Contracts, P

Do you like a big pile of source code? Well, there is an imperial buttload of source in the Visual Studio 2010 and .NET Framework 4 Training Kit . It's actually a 178 meg download, which is insane. Perhaps start your download now and get it in the morning when you get up. It's extremely well put together and I say Kudos to the folks that did it. They are better people than I. I like to explore it while watching TV myself and found myself looking through tonight. I checked my blog and while I thought I'd shared this with you before, Dear Reader, I hadn't. My bad, because it's pure gold . With C# and VB, natch. Here's an outline of what's inside. I've heard of folks setting up lunch-time study groups and going through...(read more)

Dynamic Data using Code First Entity Framework Model


I have used Dynamic Data before using LinqToEntity where my Entity model used the Data First model and the GUI.  Now I am trying to use the Code First model witht he Entity CTP 4.  I have my model created and created a new Dynamic Data site.  I read that I need to replace the default RegisterContext call:

DefaultModel.RegisterContext(typeof(PriceLoaderContext), new ContextConfiguration() { ScaffoldAllTables = true });


DefaultModel.RegisterContext(new DomainModelProvider(typeof(PriceLoaderContext)), new ContextConfiguration() { ScaffoldAllTables = true }); 

When I search further on DomainModelProvider, I find that it is part of the WCF RIA. Is this correct? Is this what I need for this to work? Has anyone else done this and got it to work?
