What faults will MySQL Connector encounter during upgrade?

This article mainly tells you about the faults that often occur during MySQL ctor upgrade. Asp is used in the past. NET + MySQL to build the system platform, using MySQL Database Connector 5.22, found that the implementation of Membership has a Bug.

Sometimes an exception is thrown, causing the website service to stop for unknown reasons.

Log on to the official MySQL website again and find that MySQL Connector has been upgraded to 6.22. Then download and upgrade the system, hoping to fix the above Bug.

As a result, the 6.22 version throws another exception, and the system that runs well cannot run.

User code does not process System. FormatException

Message = "GUID should contain 32 digits with four dashes (xxxxxxxx-xxxx-xxxxxxxxxxxx ). "

Source = "mscorlib"

StackTrace:
