Performance of built-in .NET collection sorters

There was a question asked about how to sort a List. There were several methods given from the basic List.Sort() to List.OrderBy(). The most laughable was a roll-your-own-SelectionSort. I promptly voted that down, but it made me think; wouldn't Linq's OrderBy(), applied to a list, do the same thing? myList.OrderBy(x=>x.Property).ToList()...

Who should be responsible for closing a stream

I'm writing an application that creates a "Catalog" of files, which can be attributed with other meta data files such as attachments and thumbnails.

Running asp.net mvc 2 on win 7 with .net 4.0 I have a controller action method that receives 2 DateTime objects from a form. The UI on the form uses the jQueryUi datepicker (not sure if that maters).

Finding stack overflow exceptions in a windows service

I have inherited a large and complex C# windows service project that crashes every now and then. The logging system is not logging any messages which I initially thought strange but I now understand that logging might fail if there's a stack overflow or out-of-memory exception.

Asynchronous Delegate Invocation (ADI) vs. Task Parallel Library (TPL)

I get this comment on ADI while reading Essential C# 4.0: Unfortunately, the underlying technology used by the asynchronous delegate invocation pattern is an end-of-further-development technology for distributed programming known as remoting. And although Microsoft still supports the use of asynchronous delegate invocat...

WCF exception received on closing connection with callbacks in use

Hey there all, I am using a netNamedPipeBinding to perform inter-process WCF communication from a windows app to a windows service.

regex retrieve part of a string encapsulated in ()

I just simply want to retrieve two substring of a string which take the following form. The first is a numerical value (there is only one) which is encased between parentheses, such as (12345) - this can be any number of digits (I haven't really kept any stats on length) but between 1 and 10 digits should cover it. The second substring...
