What's the best way for a .NET windows forms application to update itself?
I use a home-grown system where the application updates itself from a web service.

What is the best tool for creating an Excel Spreadsheet with C#. Ideally, I would like open source so I don't have to add any third party dependencies to my code, and I would like to avoid using Excel directly to create the file (using OLE Automation.) The .CSV file solution is easy, and is the current way I am handling this, but I...

Is there a CLR that runs on the CLR ?
I was wondering if there was a .NET-compatible CLR that was implemented using the CLI (common language infrastructure), e.g., using .NET itself, or at least if there were any resources that would help with building one. Basically, something like a .NET program that loads assemblies as MemoryStreams, parses the bytecode, constructs the t...

Asynchronous WPF Commands
Note: The code in this question is part of deSleeper if you want the full source. One of the things I wanted out of commands was a baked design for asynchronous operations. I wanted the button pressed to disable while the command was executing, and come back when complete. I wanted the actual work to be performed in a ThreadPool work ...
Infragistics V7.3 vs. V8.1
We are using the Infragistics controls for .net (both ASP.Net and WinForms) for a few years. We want to upgrade our current version (v6.3) and are in a pickle. We can upgrade to v7.3 or v8.1 but not to a later one due to licensing limitations, and we don't want to spend more money on licenses unless it is really necessary. Rumor has it t...
WPF Commands and Parameters
I'm finding the WPF command parameters to be a limitation. Perhaps that's a sign that I'm using them for the wrong purpose, but I'm still giving it a try before I scrap and take a different tack. I put together a system for executing commands asynchronously, but it's hard to use anything that requires data input. I know one common pat...

I have a DataSet that contains a few columns. One of these columns is a number - most of the time. Because it's occasionally a string, in the database it's a varchar(10) column. However, when you sort a varchar column, it sorts it like a string. What I want to do instead is to try and override this somehow so that it sorts the integers ...
Storyboards cant find ControlTemplate elments.
I've created some fairly simple XAML, and it works perfectly (at least in KAXML). The storyboards run perfectly when called from within the XAML, but when I try to access them from outside I get the error: 'buttonGlow' name cannot be found in the name scope of 'System.Windows.Controls.Button'. I am loading the XAML with a stream read...
