Hi Gustav at all -- I have got MS LightSwitch 2011 installed, and I have tried to create LightSwitch project using NorthwindNet database from our northwind.codeplex.com project - it didn't work resulting in a set of (cryptic for me) error messages: Error 5 Application definition contains critical errors. Common Error 6 Application definition contains critical errors. Client Error 7 Application definition contains critical errors. ClientGenerated Error 8 Application definition contains critical errors. Server Error 9 Application definition contains critical errors. ServerGenerated Error 1 The EntitySet property of the AssociationSetEnd 'OrderDetail' in the AssociationSet 'OrderDetails' in the Domain Source 'NorthwindNETData' cannot be resolved: The item referenced by Id 'OrderDetails' does not match the type of the property 'Microsoft.LightSwitch.EditableModel.IEditableEntitySetDefinition'.

C:\Program Files\MSBuild\Microsoft\VisualStudio\LightSwitch\v1.0\Microsoft.LightSwitch. targets 149 10 LS_Test_Application When I have got removed one non-unique indexes from ProductDetails table supposing that it was the cause of the above errors I have got VS going down/restarting and presenting me a message: +++ There are critical errors in the application definition metadata. These errors must be fixed before the project can be loaded in the designer. Check the errors in the errors window, and fix them in the text editor. When you finish it, please use the "Reload" button to reload it into the designer. ---- Sorry for my English but what they mean in the last sensence by "finish it"? - I got it as to finish ASAP my first Lightswitch "fighting session", and so I finsihed it :) If anybody here have any idea how to fix the above issue that would be very helpful here.

The organisation counts only a few hundred members, and as the backends are only 150 MB I will face no scaling issue. It is exactly what LS is targeted for, so for this reason alone I will do the test. It may, of course, prove unsatisfactory in some way and if so I will for sure choose the WinForms route which works very well for me. We have one client where I have used the click-once deployment method and it works very well. Even the smallest modification, which I can code in minutes, gets deployed at once as it just requires a few default clicks and a password to the clients local FTP server and it has been published. It can't be easier and it just works. /gustav
