Indigo installation blues

Indigo is the codename for Microsoft’s unified programming model for building connected systems. It extends the .NET Framework 2.0 with additional APIs for building secure, reliable, and transacted Web services. Microsoft released Community Technology Preview (CTP) in March 2005 to enable developers to experiment with early builds of technologies and provide them feedback. CTP is a new acronym to me but a similar concept what we call Early Access (EA). For instance, JAX-RPC 2.0 EA build was released recently and we expect developers to download the build, get familiar with the programming model and provide us feedback. Indigo is expected to provide support for the various WS-* specs floating around. Indigo will ship as part of the Windows release code-named Longhorn, scheduled for 2006. As with CTP, it will also be made available on Windows XP and Windows Server 2003. Now enough of Indigo details, lets get to my brief experience with Indigo so far.

I decided to install Indigo and get familiar with it and I need to admit that the experience is definitely not a pleasant one so far. I started on a clean slate Windows XP/SP2 machine and here is my progress bar:

1. I had to google for configuration mismatches between Visual Studio 2005 Beta2 and Indigo. It seems Visual Studio 2005 beta2 and Indigo have different .NET runtimes that are not compatible. However the CTP ISO image lists Visual Studio 2005 beta2 as the first bullet in installation process that can very easily confuse and potentially waste lot of time since it takes a while to install these monsters. And so before I know about the non compatibility, Visual Studio window will flash and then disappear, duh! Anyway, I figured out not-so-easy way of how to take care of that. And I realized I'll not be able to use the IDE that Microsoft is well known for. Is that only me or is that true for others as well ? 
2. By default, Windows XP installation in our labs do not have IIS installed (yeah, it's risky) and I was not aware that IIS needs to be installed as a separate component. So on my clean slate machine I installed .NET framework, Avalon (just for fun) and then Indigo and started playing around with Indigo samples. But then the documentation requires you to check for service extension registration. However it does not say what to do if the extension is not found registered :(. And when I tried adding an extension registration, Add button was disabled. Anyway, I took a calculated guess of uninstalling all Indigo-related stuff, installed IIS and then reinstalled all Indigo related stuff. Phew, finally I could verify that the service extension is now registered.
3. Moving along, the samples documentation mentions a Download button so that I can download the entire sample at one go, but I could not find such a button on any of the samples, specifically Getting Started sample that I started to play with. So I had to download each file individually. And even then there are so many support files (probably required by Visual Studio) so I had to hand pick only the relevant files since I'm IDE-disabled as mentioned earlier. 
4. Even when downloading the source files, I got 404 when trying to browse service.svc in the sample. I'm not sure when trying to view service.svc in the sample page, is the extension registered in my local IIS playing any role (I dont think it should but dont know for sure). So I tried stopping IIS service but still got the same 404 error. I finally created my own service.svc and copied all the relevant files in a directory.

• Hey Ann
  I was having the same issues tonight. This link helped get me past it: http://msdn.microsoft.com/Longhorn/Support/relnotes/default.aspx.
  Apparently the SSL service was not running, so running the two commands:

  net start httpfilter
  iisreset

  is the winner. i did this and got the wsdl, .svc and mex pages to display properly.

  I hope this works for you and good luck! :)

• I resolved it the day after this post and reported here. Thanks for the pointer again.
