After the workflows have been created and persisted, the console application hosting the workflow runs at or near 100% CPU usage until the timers fire and workflows reload and complete.

      • Seems that some serialization actions will be taken inside WF when run a WF from ASP.NET. It's known that in C# the event members in an object can not be serialized, we should use [field: NonSerializedAttribute()] to prevent the serialization of event members, so the values of the event members will be lost after deserialization. However, sometimes we should keep the event value during the s
