# CQRS, the book

In 2009 I have had the pleasure of spending a 2 day course and many geek beers with Greg Young talking about Domain-Driven Design specifically focussed on Command Query Responsibility Segregation (CQRS).

The example project I created based on these discussions was very well received by the community and regarded a good reference project to explain and learn the patterns that make up CQRS. I decided to add the different blog posts I wrote about the example into a single book so it is easy to find and read.

You can find the book here: https://leanpub.com/cqrs

# x86 vs x64

When running the example on a x86 machine you have to go into the /Lib/sqlite/bin/ folder 
and copy the three System.Data.SQLite.* files into the /Lib/sqlite/bin/x64/ folder. This 
is because I am developing on a x64 system. An interesting fact is that the TestDriven.Net
test runner does actually run in x86 mode, so the SQLite reference in the Test project is 
the the x86 SQLite version already. Resharper test runner acts the same.

If you have any questions or other feedback then I would love to hear about it at
