"Serialization. serializationexception: The end of the stream is encountered before the analysis is complete" SOLUTION

This problem occurs during workflow creation.
I checked it for two days and read ArticleBecause your class cannot be serialized. However, this problem still exists when you remove your classes.
After searching for variables one by one, it is found that the Web and site variables are declared as Class-level variables to cancel the variables, and the problem is solved.
Other: Some types do not support serialization. You can check them.
In addition, some private variables cannot be serialized and need to be marked as non-serialized.
