ASP.NET MVC3, WebMatrix, NuGet, IIS Express and Orchard released - The Microsoft January Web Release in Context


image At PDC10 last November I did a talk on the "Unnamed Package of Web Love", showing ASP.NET MVC3 and Razor Syntax, the NuGet Package Manager, as well as SQL Compact Edition and a little "Entity Framework Magic Unicorn." I make up my own names when I don't like what Microsoft names things, as you may notice.

Today Microsoft announced the (actual, final, honest) releases of:

  • ASP.NET MVC3 with Razor
    • Lots of new features, the new Razor syntax, more extensibility hooks, new JavaScript features, better validation, easier caching, better dynamic support, and lots more.
    • This includes the NuGet package manager and the NuGet gallery is also in early beta at http://nuget.org for folks who want to create and publish their own packages)
    • MVCScaffolding
      • Remember all that fun we had with the scaffolding experiment at PDC? Well, my teammate Steve Sanderson has taken the prototype up to version 0.8, and it's pretty fabulous. Go read his blog post, then enjoy "Install-Package MvcScaffolding." You can scaffold views, controllers, repositories, database contexts or even make your own custom scaffolder. Look for more built on scaffolding from Steve and I in the coming months.
    • Updated Beginner Tutorials for ASP.NET MVC 3 in both C# and in VB
  • NuGet
    • NuGet is a package manager for .NET. It ships with ASP.NET MVC, but you can go get it separately if you like. Installing open source libraries is as simple as "install-package elmah" - it's great fun.
  • WebMatrix (also with Razor)
    • WebMatrix is a small development environment that uses the simple Razor syntax to create websites really quickly. You can start from a gallery of existing open source applications or start from scratch. For example, Rob Conery and I wrote the little podcast site and feed for http://thisdeveloperslife.com in a day with WebMatrix.
    • NuGet package management is built into WebMatrix, too! Make a new site, run it, and hit /_admin. Dance.
  • IIS 7.5 Express
    • Yes, you can install it on its own. It's IIS, except it runs as a user process rather than a service. Cassini (Visual Developer Web Server) is dead! It's "just in time" IIS. There when you need it, and not running when it's not used.
    • This is the web server that Web Matrix uses today, but it'll be enabled in Visual Studio 2010 when SP1 comes out.
  • SQL Compact Edition 4
    • SQL Compact Edition is sweet because is a tiny in-process (no services, don't need to be admin) database that's great for small sites that aren't ready for SQL Server proper. It's xcopy-deployable and runs nicely on hosted sites. It's the default database for WebMatrix and I'm using it in Visual Studio for sites where my database isn't big enough to justify a SQL license.
    • You can use SQL Compact today in Visual Studio at runtime, much like I did in my PDC talk, but you won't be able to design and open your database in VS until SP1. (You can use this Non-MS CodePlex project temporarily, but I didn't tell you.)
  • Web Farm Framework 2.0 and Web Deploy
    • Makes setting up multiple servers way easier. Treat and manage groups of servers, use ARR for load-balancing (or use 3rd party balancers), and upgrade, switch, and add servers with PowerShell. Mmm....PowerShell.
  • Orchard 1.0
    • This free, open-source content management system is ready to go. The release is published on the Orchard CodePlex website and Microsoft Web Application Gallery. You can use Orchard all up, or you can take it apart and just use pieces. Mix and match as you like.

It's the January Web Release, say I, and the easiest way to get it is with Web Platform Installer 3.0, which also went live today. Using direct links to products within the Web Platform installer will automatically add any dependencies you might need.

Now what? I'm freaking out!

Folks sometimes say "slow down, you're freaking me out, this is too much new stuff. What about my current stuff?" Here's a few statements from me personally on today's releases.

  • Just because ASP.NET MVC 3 came out today, doesn't mean WebForms doesn't have some cool features coming. Remember that "ASP.NET > ASP.NET MVC". You'll see features and improvements from both technologies move between MVC and WebForms.
  • IIS Express will integrate with VS2010 in SP1 and work with both WebForms and MVC.
  • You can mix Razor Views and Web Forms Views within MVC. The creation/existence of Razor doesn't obviate your existing work.
  • SQL Compact works great with WebForms as well as ASP.NET MVC, not to mention any .NET project. Ever want a tiny database for a command-line app and didn't want the headache? Bam.
  • SQL Compact database can be upgraded into full SQL Server databases when/if you outgrow SQL Compact.
  • While NuGet is bundled with ASP.NET MVC in today's release, you can use it for any .NET project type. Most NuGet libraries are not specific to ASP.NET MVC.

As I've said before, Microsoft is creating new LEGO pieces for software development to round our existing collection of bricks out. Be exited about these bricks, but remember they augment the existing ones, not replace them.

What now?

I'd recommend you go get MVC3 and WebMatrix, preferably at the same time via one of these Web Platform links. That should get you all these other nice things chained in. In the spring when VS2010 SP1 comes out, the tooling and management bits for SQL Compact and IIS Express will be enabled.

Stuff to Get

ReSharper Updated

One other note, the folks at JetBrains were ready for this and spun a new build of ReSharper, so ReSharper 5.1.2 doesn’t interfere with Visual Studio IntelliSense in ASP.NET MVC 3 Razor syntax. Earlier ReSharper 5.x builds had certain issues with Razor IntelliSense that are addressed in 5.1.2. Specifically, ReSharper 5.1.2 doesn’t prevent Visual Studio from automatically providing its own IntelliSense in .cshtml and .vbhtml web pages anymore: both code completion and Parameter Info work as expected. Other than that, ReSharper 5.x doesn’t provide any additional support for Razor: only ReSharper 6 will bring full support for this view engine. Pre-release ReSharper 6 builds are currently available via Early Access Program, so if you're a ReSharper user, be aware!

Enjoy.
