In some my previous post a mentioned issue with iterating though IEnumerable<ActivityParty> collection.

CRM 2011 plugins

Yesterday I tried to write simple plugin against Dynamics CRM 2011. This plugin should update some property of contact in case if some activity is completed. In particular we have to set property new_lastcontacteddate if phone call is completed. In previous CRM version such plugin was arduous since we was able use only DynamicEntity. WSDL generated classes were not suitable in plugins since Microsoft.Crm.Sdk.ICrmService didn't support those generated classes. In order to use strongly typed classes in plugin in CRM 4.0 you could create new CrmService object in the plugin, but it is not good idea
