After a few months of using FluentValidation I asked its author Jeremy Skinner if it were possible to integrate this with xVal. At that time it was not possible because there were no easy way to access the properties needed by xVal. After submitting a few patches, we now have a solution which enables xVal [...]
A few weeks ago I found the Fluent Validation framework by Jeremy Skinner. I needed to conditionally validate a model depending on an application setting. eg.

In my previous post I used custom sql query and transformed the results into a nested class. However you may have overlooked way I got the data into a class. It quite easy and will work with all database connectors that implement IDbConnection.
Here is how its done. We use the DataContext that came with and [...]
Back in the days of Classic ASP, when you had a one too many relationship displaying the data was pretty painful. You would do things like
var reference_number_old = "$##%@";
while (recordsExist)

Yes…Finally…I have full control of my HTML again, but am still able to work with a great language like C#. MVC is here and its great. I’m absolutely loving it. But how the heck do you get it to work under IIS6. What if I want extensionless URL’s? Here is a few options for you.
