Hi Ian Sometimes it just feels cool to be skeptical. I liked Bill's comments on the matter.
If the performance issues can be resolved there is definitely a spot for Lightswitch in my toolbox.

Googling "Lightswitch slow" shows I aren't the only person experiencing speed issues. I wasn't plannining to use Lightswitch for migration. Rather for new solutions that need quick CRUD forms.... I am hoping to hear more news from people with better experience of the speed.

Have you done other metrics to compare such as a windows.forms app using the same data, and a Silverlight app using the same data ? As to advice: it's hard to say in your particular case. If you have an existing VB6 application, the first questions that need to be answered is what do you want to do with it, what are the goals of the migration? The "83 fields" part does make me wonder if this could be presented to the user better. Are you using tabs, logical groupings of fields? If so, each group in a tab should be able to load async / lazily. I wouldn't say that Lightswitch is only for web apps; rather I'd say its primary target is distributed apps. For standalone single user applications the architecture it uses is probably overkill, although there are benefits even in those cases to move the data to the cloud. For apps with the data stored in the cloud (such as Azure), I think Lightswitch presents a really low cost way of getting good quality data screens and letting the customers modify what they want |-----Original Message----- |From: [email protected] [mailto:ozdotnet- |[email protected]] On Behalf Of Kirsten Greed |Sent: Tuesday, 2 August 2011 8:08 AM |To: 'ozDotNet' |Subject: RE: Lightswitch - really clever - really slow | | |Hi Bill | |The test app I created, released on my local computer, takes 5 seconds load the |data entry form. |Then 3 seconds to return to the list when I click the cancel button There are 83 |fields on the form. |This compares to less than half a second for my old VB6 application | |I am running Windows XP SP3 |AMD Phenom(tm) IIX3 720 Processor 3.01GHZ, 3.25GB Ram Pyhsical Address |Extension | |I also found the development experience frustrating because of the speed | |Any advice?
