Memory in .NET - (Vagueness Of .NET Memory Management)

Thu, 15 Dec 2011 15:25:25 GMT

"Variables" are simply storage locations for data becuase it is really hard to pragramme against the memory address. It means, a variable is just an association between a name and memory slot. You can place data into them and retrieve their contents as part of a C# expression. The size of that slot, and the interpretation of the value is controlled through "Types" - and this is where the difference between value types and reference types comes in.....

CLR Inside Out: Investigating .NET Memory Issues

Mon, 12 Dec 2011 06:26:46 GMT

Uncovering and correcting memory issues in managed applications can be difficult. Memory issues manifest themselves in different ways. For example, you may observe your application's memory usage growing unboundedly, eventually resulting in an Out Of Memory (OOM) exception. (Your application may even throw out-of-memory exceptions when there is plenty of physical memory available.

Introduction to the Roslyn Scripting API

Tue, 06 Dec 2011 20:31:07 GMT

In this post, Brian Rasmussen takes a look at how the Roslyn Scripting API can enable applications to evaluate code at runtime. While this has been possible since the dawn of .NET through the use of Reflection, Lightweight Code Generation, CodeDom, etc., it has never been particularly easy. All of these mechanisms are either hard to use, require MSIL knowledge, or just have inherent limitations.

Secure Strings - CodeProject

Fri, 11 Nov 2011 17:27:32 GMT

Abhishek Goenka gives a short introduction to the .NET Framework's SecureString class which stores strings in memory in an encrypted form so that the data contained in the strings in memory cannot easily be ready from outside the application.

5 Tips and Techniques for Avoiding Automatic Garbage Collections

Fri, 04 Nov 2011 14:51:31 GMT

We've seen a few articles lately on ensuring that your memory is properly cleaned up during garbage collection, but today Michael McLaughlin comes in with tips to avoid automatic collection of your objects. Generally speaking, this is for performance reasons. Garbage collection in .Net 4 and earlier happens automatically and blocks program execution, which can be disastrous for certain types of applications (games, real-time analysis, etc).

IDisposable and Thread Safety

Thu, 03 Nov 2011 14:15:21 GMT

IDisposable is a standard interface in the .NET framework. This article discusses the importance of using it in parallel or multithread programming.

Is That a WeakReference In Your Gen 2 or Are You Just Glad to See Me?

Wed, 02 Nov 2011 01:28:32 GMT

John Robbins walks us through debugging an application which is not clearing its memory during garbage collection due to WeakReferences. He shows us how to use the tools available to us to trace the memory problem all the way back to the source.

Memory Allocation Improvements in .Net 4.5

Tue, 04 Oct 2011 18:51:56 GMT

Surupa Biswas and Maoni Stephens from the Garbage Collection Feature Team at Microsoft share with us some improvements to memory allocation in .Net 4.5, specifically relating to large object allocation. Improvements have been made to how fragmented memory is allocated and used on the heap, as well as balancing large object allocation between heaps when in server GC mode. The latter improvement has seen significant performance gains.

.NET 4.5 Framework: Backwards compatibility and you

Tue, 27 Sep 2011 15:20:14 GMT

Brandon Bray gives us some information on backwards compatibility with the upcoming .NET Framework 4.5. This next version of the framework will not be a side-by-side installation like previous releases, but will instead replace version 4 when installed on a users machine. The goal is to be fully backwards compatible with version 4, but the possibility for breakage exists.

Windows 8: What's New? - Arik Poznanski's Blog

Sun, 18 Sep 2011 21:25:33 GMT

Got back from Build conference. Since I expect many people will ask me "So, what's new?" and since the answer is rather complex, I figured I should try to write a post about it, so here goes.

String-Interning-in-net.aspx

Thu, 04 Aug 2011 17:40:27 GMT

We all know that the way .net handles a string is not optimal and uses up lot of memory, thought there are reason to do like this. But if we have more string objects or comparison inside our assembly then in this case surely it is going to be a performance hit. But here what really happens is framework itself take cares at least some part of it using the concept of Sting Interning. So what is String interning in Microsoft .net. How does it helps the C# code Execution.. It seems that there is an internal hashtable maintained with the actual string value and it's reference to managed heap. And two methods help us to handle this hash table This is the "Intern" and "IsInterned" methods which is part of string manipulation class.
