NOTE: Java programmers: please refer to my JVM Profilers page.
Editions and Installers
Red-gate.com has 3 different products for developers, with separate licenses.
There are different pages for each product:

Sample C# Code
Nerd Diner Sample App
http://nerddinner.com presents a sample .NET MVC app.
The app enables registered users to create, edit, and delete dinners.
The app was written in 2009 by Scott Hanselman, Scott Guthrie, and others at Microsoft.
The app was built to be run locally because its source code is available at
http://nerddinner.codeplex.com (http://tinyurl.com/aspnetmvc). The website describes new features added on August 2011 along with updates for ASP.NET MVC 3.
PROTIP: Use Git to clone the more recent (2016) MVC 5 version on GitHub:
However, other sites have not been updated:
