I tried to upgrade a lightswitch application from NetAdvantage Vol.11.2 to Vol.12.1 folllowing procedure described in blog post.

Executing the upgraded application returned an error in file

~\ClientGenerated\Properties\ApplicationDefinitionLoader.cs

regarding the "using System.Xml.Linq;" and XDocument statements.

I solved this by:

- selecting File view

- Show All files

- Right click on Client Generated- References

- adding a .NET reference to System.Xml.Linq

I am curious as to why this was necessary.

Hi Max,

This is an issue in the VS LightSwitch IDE. We have logged issue number  685376 in connect. microsoft.com about this long time ago.

In case of any other questions, please let me know.

Best regards,

Hi Anatoli,

I upgraded a lightswitch application from NetAdvantage
Vol.11.1 to Vol.11.2 (no problem),
then from Vol.11.2 to Vol.12.1 (having to add a .NET reference to System.Xml.Linq in Client Generated- References, as I mentionned earlier).
Now working fine.

Now when I convert it to VS 2012 RC, I get the following errors:
Upon load,
 Cannot find ~\_Pvt_Extensions\Infragistics.LightSwitch.Extensions\IDE\Reference\Microsoft.LightSwitch.Design.Utilities.dll

Upon execute,
 Cannot load 'InfragisticsSL5.Controls.Grids.XamPivotGrid.v11.2, Version=11.2.20112.1046,Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb'

Does this mean that my application cannot be upgraded to VS 2012 RC?
