Over the years, I've shared a lot of code as part of my blogging, but I didn't do a particularly good job of making the code easily available outside of the individual blog posts. I also realized I didn't even have all the code where I could easily get to it from my PC!
To remedy those problems, I've consolidated all the non-trivial code I've shared in blog posts in a single repository and made it available on GitHub here.
Many of the samples were originally written for Dynamics CRM 2011, but each solution has been updated to use the Microsoft Dynamics CRM 2013 Service Pack 1 Update Rollup 1 SDK (version 6.1.1 installed from NuGet). I have verified that each solution builds, but I have not necessarily deployed or tested, so the code is all "use at your own risk."
