I keep getting this weird error in a Prism application that I am working on.


Method 'get_Regions' in type 'Microsoft.Practices.Composite.Wpf.Regions.RegionManager' from assembly 'Microsoft.Practices.Composite.Wpf, Version=, Culture=neutral, PublicKeyToken=null' does not have an implementation.


Anyone recognise the problem?

Hi Bob,

The assembly name you mention is from Prism-v1. In Prism-v2 there were some changes done in the implementation of the RegionManager class. One possible reason for the error you are getting if you upgraded your solution to Prism-v2 but left a Prism-v1 assembly without upgrade.

Please let me know if this helps.
