In this episode of 10-4, we introduce a new feature coming along with Visual Studio 2010 and the .NET Framework 4.0: sentient DSLs. If you've become intrigued with all the hype around leveraging domain-specific languages, but you're concerned about the added complexity that comes with having to learn a bunch of different grammars, then sentient DSLs are for you. Write the code that you think makes sense, and allow the application to create itself. Coding should be fun, and most importantly, it should be easy.

    I downloaded the sample app and typed "fix global financial meltdown".  It build successfully and outputed all the appropriate files.  However this morning when I looked at my stock portfolio I was still dead in the water.  Is there a compiler switch I forgot to set?

    Please remember that this is a CTP of Sentient DSL's, so your results may vary... you might want to consider logging an official bug on Connect.Microsoft.com.

    Meanwhile, if you want to try out the Sentient DSL's SDK then you might be able to fix this yourself.

    Sun has a working version, open sourced, dynamically linked, named Domain Specific Hibernation, that does that exactly, why do you think Oracle bought them?

    Obamas Plan    
        Fix global warming
        End all wars
        Fix economy

    A friend of mine just recomended this post to me, and we're planning to leave programming hahaha.

    Hmmm, I think this may actually be more efficient than the system I'm working on which will generate all possible code and then categorize the working applications.  There I go again thinking I've come up with something good and then along comes Microsoft...

    Went browsing through the archives, and this caught my eye. Initially I thought I read 'sentient DLLs', and my first thought was "Good morning Dave.".

    Second thought after seeing this was "Nice sales pitch. Useless.". Third, "Amazing framework indeed. So flexible you'll hit a brick wall the second you try anything important.". And my final conclusion was that I was indeed rick rolled, I hadn't noticed the date and had considered this to be an actual episode.

    Tongue Out Well done!

    Hmm I think I found a bug in the OS generator:

    Awesome OS


      Theme = "Best of the best",

      Architecture = "Pan-Dynamic",

      User = ture,


    I compiled it ran it and it just tells me: '42'
