6 Appendix A: Product Behavior
This document specifies version-specific details in the Microsoft .NET Framework. For information about which versions of .NET Framework are available in each released Windows product or as supplemental software, see .NET Framework.
The information in this specification is applicable to the following Microsoft products or supplemental software. References to product versions include released service packs:
Microsoft .NET Framework 3.0
Microsoft .NET Framework 3.5
Microsoft .NET Framework 4.0
Microsoft .NET Framework 4.5
Exceptions, if any, are noted below. If a service pack or Quick Fix Engineering (QFE) number appears with the product version, behavior changed in that service pack or QFE. The new behavior also applies to subsequent service packs of the product unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.
Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms SHOULD or SHOULD NOT implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term MAY implies that the product does not follow the prescription.
<1> Section 2.1: Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows 7 ignore the SOAP ActivityId Header Block if the client/server is configured to not participate in correlated tracing. The client/server can be configured to not participate in correlated tracing by not specifying "activityTracing" for the switchValue attribute associated with trace sources in the Application Configuration (App.Config) file. Additionally, the server also requires that the "propagateActivity" attribute needs to be set to false for the trace source.
