[dba-VB] Rapid Application Development: LightSwitch 2011

Hi Shamil

No, I haven't got that far.

My first guess was that the table schemes of Northwind perhaps didn't correlate 100% with that expected by LightSwitch.

But the link you provided tells that a separate instance of SQL Server Express 2005/2008 (not any other version) is required to support LS itself during development to not mix up "development data" with your application data (user data). 

That I didn't know about, and it may cause trouble around where you use the development version of SQL Server 2008 for your local work.

Hi All --

To avoid issues with ProductDetails table I have just checked it out from

got infamous:

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

AssociationSet 'OrderDetails' in the Domain Source 'NorthwindNETData' cannot

property 'Microsoft.LightSwitch.EditableModel.IEditableEntitySetDefinition'.

Error 2 The EntitySet property of the AssociationSetEnd 'OrderDetail' in the
AssociationSet 'ProductOrders' in the Domain Source 'NorthwindNETData'
cannot be resolved:

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.

Thank you.
