I spent couple of months for developing a web Project in lightswitch and I told my colic to try this great Microsoft tool especially with the addition of The DevExpress Team....
now when we trying to go live in our company... we receive the following error:
"lightswitch web deployment could not load file or assembly 'devexpress.xpf.printing.V11.1.core, version = 188.8.131.52, culture=neutral, productkey = null' or one of its dependencies. the system cannot find the file specified." ....... AS IN ATTACHED PHOTO
I make the instruction of copy local and the correction of the webconfig file in the development machine and its working perfectly.
but when I deploy as a web application this error arise.
I copy the a the dll file (including devexpress.xpf.printing.V11.1.core.dll) from the bin file of the sorce project in my development computer but if not work also.
I change the application pool to ASP.4....
I spent 3 days goggling the issue with no any solution.
Please we was fighting with the time to finalize the project but now we stop working with the other application project till complete the go alive for this Web Application.

Please find the attachment of the screen of the debugging in development computer (by running the resource) as web
their is no any problems....
but when we import the package to the server the exception will run...
"Could not load file or assembly 'DevExpress.Xpf.Printing.v11.1.Core, Version=184.108.40.206..."
is there any prerequisites to be add to the server...
I try to add this assembly -DevExpress.Xpf.Printing.v11.1.Core.dll- to GAC but I cannot.
To resolve this issue, you might need to edit the ClientGenerated/Config.xml file. In the <ExtensionAssemblies> section, remove all references to the DevExpress assemblies, except references to our XtraReports extension assemblies (DevExpress.XtraReports.v11.1.LightSwitch.Common and DevExpress.XtraReports.v11.1.LightSwitch.Client).
Please let us know whether or not this information helps you.
thanks you Mr.Illot
I did the instruction above and I repack another web and I end with error:
(load operation failed for query 'getauthenticationinfo'. exception of type 'system.servicemodel.domainservice.client.domainoperationexeption' was thrown.)
As is attachment
I don't know if this is because of DevExpress?
But I believe that DevExpress team experience with this issues.
1- I use form authentication in my application
2- I use windows integration security " and follow the instruction as in the bethmassi link
3- the import done without any problems
4- I use the DeaultAppPool for my application
5- I install silver for developer edition
but I get the exception
I change the application pool with the admin as identity..
and I re-install the net-framework...
the get-authentication Not solved with the following error:
((Load operation failed for query 'GetAuthenticationInfo'. Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information)
Thank you for your reply. We suggest that you try to find the cause of the problem by using the approach posted in the Diagnosing Problems in a Deployed 3-Tier LightSwitch Application article.
If this information does not help you, please post here the ClientGenerated/Config.xml file for the examination.
Please keep us informed of your progress.
