KB4481031 for .NET Framework 4.7.2 and 3.5 Windows 10, 1809 detail
This update addresses the following issues:
- A garbage collection problem in the JIT compiled code.
- Service becoming unavailable due to a race condition which affects IIS-hosted Net.tcp WCF services after restarting the port-sharing service.
- The issues in relation to Special mode causing SerializationException and COMException
- The cumulative update works on Special mode in which the logical call context is unable to be serializable. The problem creates SerializationException when secondary app domains call back to the default domain to gather evidence.
- The special mode in which the thread is running under an impersonated user token rather the primary process token that causes COMException when evidence examination triggers urlmon initialization in the system. This, as a result, fails since it assumes a level of registry access that is not always existing when impersonating
