Different Routes for Different Hosts Using Constraints

I had the pleasure of visiting some guys in Munich this week to talk about ASP.NET MVC. Well, the time with them was a pleasure, but I did have two awful airport experiences due to snow in 48 hours!

Offline Data Cache in Windows Phone 7

Recently I put together samples for different types of validation for some customers, and one of those was Conditional Validation – that is “this field is required if another field is true”, and such like.

jQuery.validate and Html.ValidationSummary playing nice together

A customer recently asked me how to get MVC with the MVC Futures project’s MicrosoftMvcJQueryValidation.js adapter file to play nicely with the Validation Summary HTML helper. It turns out that this functionality isn’t built into the adapter script file. They also pointed me at this post by Soe Tun that gets things up and running….
