I just hope it's sooner than later, because I think we'll need a ton of guidance on this and a lot of help wading through the change of perspective necessary to utililize this kind of platform.<BR><BR>I think Oslo will have one of the biggest learning curves in a very long time.&nbsp; I have just recently been able to teach and encourage a fellow developer to use lamda expressions in C# 3.5 to solve a problem he was having, much simpler than he would ever have done before, but it took a year of encouragement to help him begin to "see the light".&nbsp; I am afraid that since I have to point people to a video of the PDC to even try to explain Oslo, that it will be a very long and arduous task to bring Oslo to market.&nbsp; I look forward to the day that I can go into a contract where people are using DSLs to define the system, but I really have strong doubts about it happening anytime soon.&nbsp; What kind of roadmap does the Oslo team see, for the market penetration and developer mindshare that Oslo will achieve?<BR><BR>Please concentrate some effort into making a "real-world application" built on Oslo, so we can use it to guide ourselves and others.</P>http://channel9.msdn.com/posts/Charles/Chris-Sells-History-of-DevCon/?CommentID=468845Tue, 12 May 2009 01:19:40 GMThttp://channel9.msdn.com/posts/Charles/Chris-Sells-History-of-DevCon/?CommentID=4688450http://channel9.msdn.com/468845/WebViewBug.aspx?EVT=0&nbsp;If I am defining a schema, language, repository and have customers using this system, how do I update the language and deal with migration?&nbsp; The flexibility of being able to change the language, that is designed to be understandable by our customers sounds great in theory but what about&#8230;Richard.Hein0http://channel9.msdn.com/468845/Trackback.aspx
