The Assembly Matching Rule allows developers, operators, and administrators to select target classes based on the file name of the assembly.

Note

The Policy Injection Application Block includes matching rule configuration placeholders that provide backward compatibility. The implementation of matching rules is described in the Unity Application Block documentation. For more information, see The Assembly Matching Rule in the Unity Application Block documentation.

Configuration Settings of the Assembly Matching Rule

The following configuration settings are available for the Assembly Matching Rule:

  • Match (String). This can be the name and version; the name, version and culture; or the full assembly name of the assembly excluding the .dll file name extension. It cannot include wildcard characters. The following are some examples:
    • "Contoso.BusinessObjects.Sales"
    • "Contoso.BusinessObjects.Sales, Contoso.BusinessObjects"
    • "Contoso.BusinessObjects.Sales, Contoso.BusinessObjects, Version=1.0.0.0"
    • "Contoso.BusinessObjects.Sales, Contoso.BusinessObjects, Version=1.0.0.0, Culture=neutral"
    • "Contoso.BusinessObjects.Sales, Contoso.BusinessObjects, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
