We were beginning to start on an enterprise application using silverlight.
However after reading this post we doubt whether it is the right choice going forward.
The post says that, according to
Microsoft’s declaration in PDC 2010,
Microsoft has changed their strategy
regarding silverlight and they no
longer view it as their technology to
deliver cross platform applications.
Instead they are targeting silverlight
as their development platform for
Windows phone 7.
Is this correct? Should we still continue with silverlight or go back to ASP.NET WebForms\MVC?
The Scope of the application is basically intranet with Windows 2008 servers and Windows XP and Windows 7 clients. However a subset of functionality needs to be available to the external users over the internet. There we cannot have any restrictions on what OS users can use.
based on the info you gave, I can’t conclude whether silverlight is the way to go. But what I do know is that a number of Microsofties wrote some blogposts about the things said about Silverlight on the pdc. For example John Papa, Bob Muglia and Scott Guthrie.
Update about the scope
I think you already gave the answer when you described the scope of the application. A part of the application will be available to external users and you cannot have any restriction about the OS they are running. With that requirement I think Silverlight is not the best way to go. Not because the rumours about its future but because of its platform indepency. What are the reasons not to go for a ASP.NET/web solution? Silverlight doesn’t work on each OS whereas plain HTML will work everywhere. (ok you need a descent browser)
Although for a good advice I’d need more information about the application.
