The ASP.NET MVC website is currently on MVC 3, so the sample applications, specifically MVC Music Store, have also been updated to MVC 3 with Razor view engine.
If you want to download the “ASPX” view engine version of the sample applications, you can do so in CodePlex website. All previous versions are also available.
Here’s the link to MVC Music Store, ASPX view engine version: MVC Music Store v0.8. The cool thing is, you can also download the step by step tutorial for this version in the PDF format.
