Based on a Memory Efficient Programming question on StackOverflow ..... I want to know about Memory Efficient C# Programming.... Any good Websites/Blogs/Books to know about Memory Efficient C# Programming.....
EDIT:
Some tips how to write Memory Efficient C# Programming....
Rico Mariani's blog is good for general performance, although it's not updated terribly frequently.
Maoni Stephen's blog has a lot of details on the inner workings of the .NET garbage collector.
It doesn't give explicit tips on how to optimize your code, but knowing how the GC works, will help you make the right decisions in many cases.
You may also want to check this questions, as it deals with reducing memory usage of .NET applications.
Along with Websites/Blogs/Books, you should consider Profiler tools too, that will show you the problems in real time...
this post Best C# Profiler? discusses the tools in detail.
Cheers
