I am attempting to rebuild the crm demo from scratch to get a better understanding of how prism is being implimented. When ever I have a module with any region controls in the view  I recieve an
UpdateRegionsException
An exception occurred while trying to create region objects.
    - The most likely causing exception was: 'System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.Practices.Prism.Regions.Behaviors.RegionCreationException: An exception occurred while creating a region with name 'ContactListRegion'.

{Microsoft.Practices.Prism.Regions.Behaviors.DelayedRegionCreationBehavior.CreateRegion(DependencyObject targetElement, String regionName).  ---> Microsoft.Practices.ServiceLocation.ActivationException: Activation error occured while trying to get instance of type AutoPopulateExportedViewsBehavior, key "" ---> System.InvalidOperationException: Sequence contains more than one element
   at System.Linq.Enumerable.Single[TSource](IEnumerable`1 source)

Hello Jason,

At first glance it seems that you have several copies of AutoPopulateExportedViewsBehavior in memory and MEF can’t decide which one to use.

If you have an Infrastructure project with the behavior inside, which you reference among your other projects, make sure you have CopyLocal=false set on the project reference and on Prism & MEF assemblies too.

If you want to use the AutoPopulateExportedViews behavior, check out Prism’s StockTrader Reference Implementation.
They are using a very nice architecture we tried to follow.
You can view it by running the “Desktop & Silverlight - Open RI - StockTrader Reference Implementation.bat” file in Prism’s root folder. Their help describes the views/region registration process too.

Also, check out our LOB Chronicles series, especially posts #7 and #8. Evan has described our approach on views and regions there.

Please contact us if there are any more problems.

All the best,
the Telerik team

Greetings,

Would it be possible to get the SQL scripts to install the database for the CRM demo. I am getting conflicts because I have the latest version SQL Server 2008 SP2 and the demo comes with database version 661 my instance of SQL supports 662...

Thanks.

Hello Gonzalo,

I have attached the generation script.
It will also be available in one of the next CRM source code uploads.

If there are any problems with the database, you can change the script.

Feel free to contact us if you have any more issues.

Excellent!

Have a great day!

Thank you, that solved that problem.

Hi,

Were you successful in getting the SQL pieces to work from the sample?  I am attempting to reference the sample CRM during the trial period to see how challenging it will be to create some other dashboards after the trial concludes.

Thanks in advance.
