Episode twenty five is live!

This week we give away Joe’s stuff, we break up with IE8 like a big boy, Joe and Allen get excited about readme files, and we argue about which is worse: bad code or bad architecture. That and more in this week’s episode where we explore the new bits in ASP.NET 5.

News & Updates

  • We give away Joe’s stuff! That was easy, maybe we should give away more of his stuff. Who won? Keep reading.
  • IE sucks. Chrome sucks. Firefox sucks. Maybe it’s just me. While we patiently await Microsoft’s release of their new browser, codename Spartan, we break up with IE8 like a grown man. By tweeting it. Read the best break ups or submit your own at BreakUpWithIE8.com. Oh IE8, your ad campaign will not be forgotten.
  • We argue which is the lesser evil: Bad Architecture or Bad Code. Join the conversation!

ASP.NET 5

  • In three new exciting flavors: Full .NET CLR, Core CLR (a.k.a. cloud-optimized runtime), and the Cross-Platform CLR.
  • MVC, Web API, and Web Pages have been unified.
  • Dependency Injection is now part of your project. Not everyone will be excited. Just go to Google and start typing “dependency injection is” and see some of the suggestions.
  • NuGet all the things. Modularity is good.
  • New JSON structure for project files. Want a new file in the project? Simply drop it into the directory. Michael is excited that merge conflicts will decrease.
  • Side-by-side versioning. Bundle the .NET runtime with your app.
  • Microsoft felt more package managers were necessary, so all of them are in use. All of them. Just kidding, it’s only Nuget, NPM, Bower, … /8)
  • Joe and/or Allen are very excited about the new Project_Readme.html files. Wait, what?

What did it take to run ASP.NET 5 on a clean instance of OSX?

Here’s everything Michael did to get C# code running on a Mac for the first time.

  1. Open up the App Store and install Xcode. You will need to accept the Xcode license. For the lazy, the next step *should* prompt you to accept it.
  2. Install Homebrew:
    • ruby -e “$(curl -fsSl https://raw.githubusercontent.com/Homebrew/install/master/install)”
  3. Install Mono and the DNVM (previously known as the KVM):
    • brew tap aspnet/k
    • brew install kvm
  4. Install Node.js.
  5. Install Yeoman:
    • npm install -g generator-aspnet
  6. Install Grunt:
    • npm install -g grunt-cli
  7. Install Bower:
    • npm install -g bower
  8. Apparently after all of the installs above, my path still didn’t include the location of kvm.sh. So I sourced it:
    • source kvm.sh
  9. Use Yeoman to generate an ASP web app:
    • yo aspnet (follow the on screen instructions)
  10. About now, it’s time for Homebrew to actually bring me a brew. Michael prefers Guinness.
  11. Change directory into your newly generated app dir.
  12. Restore all of the NuGet packages:
    • kpm restore
  13. Build the app:
    • kpm build
  14. Start the web server:
    • k kestrel
  15. Did you get a “too many open files” exception? Yeah me, too. Turns out to be a bug in Mono. Try this workaround:
    • export MONO_MANAGED_WATCHER=disabled
  16. Start the web server again:
    • k kestrel
  17. To quit the web server, simply press the ENTER key. Michael noted in the episode that pressing *any* other key required using “kill -9 _PID_” to stop it (where _PID_ is the process ID of the running kestrel instance). There is a request to make this more obvious.

Tip & Tricks

  • Tilt 3D – View your code like a cityscape. Or use it to see how your divs stack up, it’s up to you.
  • MacBook Retina causing you to have DPI issues with your 2nd monitor when booted to Windows? #FirstWorldProblems. Use the Windows key + the plus key to zoom in. Or the minus key to zoom out. Or the ESC key to exit. Now you can see those tiny letters.
  • SqlPin – Have some SQL statement that you’d like to have repeatedly ran? Thanks to @leeenglestone now you can.
