SYMPTOMS
The ParameterInfo class is a member of the System.Reflection namespace. You can use the ParameterInfo class to discover the attributes of a parameter and to gain access to parameter metadata.
 * The value of the DefaultValue property of the ParameterInfo class indicates the default value if the parameter has a default value.
 * The value of the DefaultValue property of the ParameterInfo class is System.DBNull if the parameter does not have a default value.

If you gain access to the ParameterInfo.DefaultValue property of an internal runtime Type through another application domain, the returned value should indicate the default value of the parameter. However, the returned value is System.DBNull. This value is incorrect.
