CRM ServiceVersion Property: Deprecated

Starting with version 4.0 of CRM, we have deprecated the ServiceVersion number (returned in response to a ServiceInfoGet SOAP request and available as a shared property on the AppService class) for the Infinity service. 4.0 returns “300” for this version number, which was the same value returned for CRM 3.0.
 
In 5.0, we will mark this property as deprecated with a .Net annotation and will change it to be a large number, 9999. We do not currently have plans to change it again in the future.
 
The ServiceInfoGet call also returns the AssemblyVersion which tracks the actual version of the application. Customization developers should be encouraged to use this version number to branch behavior for different application versions.
