I'd like to do some processing and statistics calculations over the .NET framework's classes and methods. Can I get the documentation in an easily parseable format? Or am I doomed to scrap MSDN? ...
Excuse the title of this post, but I can't really think of a more creative title. I am calling a 3rd party web service where the authors are ordering transaction results from most recent. The total transaction count is greater than 100 000. To make matters more interesting the web service sends down complex objects representing each tr...
I'm trying to understand how to implement replaceable components, or a service provider interface, in the .NET world. I suspect that I just don't know the appropriate terminology to search for. Specifically, I'm playing around with a Matrix class that has different backends. At its simplest, a matrix provides two-parameter get and set...

I just created a simple .NET Windows service. My users are supposed to download it from my site and install it on their computers. So, from various forum posts (including this site) I know that in order to do this I need an installer. Or I can just give them service files and instruct how to install it. I begun with creating a setup proj...
Hi everyone, I'm new to windows services, so pardon the basic nature of this post. I've been tasked with updating an existing service and had some questions about how they work and keep running in the background. I assume a loop of some sort is usually in play, but in the case below I'm not sure how it works and why it doesn't stop ...

Diet node occurs randomly in the XML, so i need to find the node as Diet and get its child elements and save it to DB. Assume that Diet is not only one line, it has 10-1...
Disclaimer: My posts are apparently always verbose. If you happen to know the answer to the title question, feel free to just answer it without reading my extended discussion below. The System.Threading.Interlocked class provides some very useful methods to assist in writing thread-safe code. One of the more complex methods is Compare...
Hi, I have an application which generates a large FixedDocumentSequence. Which has two option either to Print to a printer or save it as a XPS file format.

For whatever reason, I can't seem to get the list of types in a referenced assembly. Not only that, I can't even seem to be able to get to this referenced assembly. I tried AppDomain.CurrentDomain.GetAssemblies(), but it only returns assemblies that have already been loaded into memory. I tried Assembly.GetExecutingAssembly().GetRefer...

In my ASP.NET MVC2 application, I have a ViewModel class called UserCreateViewModel. In this class, there are a number of properties that directly map to a LINQ-to-SQL class, called User. I'm using AutoMapper to perform this mapping and it works fine. In my Create action of the UserController, I receive a partially complete UserCreateV...
(line of code of interest is the last one, the rest is just for a full representation) Using the following code, I wanted to take VOTERS until I exceeded the maximum votes needed, but it stops right before reaching that maximum number of votes, so my voters pool has 1 fewer voter than I wanted. Is there a clean way in LINQ where I cou...
Taking the following code, Resharper tells me that voicesSoFar and voicesNeededMaximum cause "access to a modified closure". I read about these but what puzzles me here is that Resharper suggests fixing this by extracting the variables to right before the LINQ query. But that is where they are already! Resharper stops complaining if I m...
