Dnspy can't compile MySql.Data

I have deobfuscated an executable file with de4dot and Dnspy. I can change and compile most of the classes but, I can't change and compile the ones that has MySql methods in it. It gives me an error: type or namespace name 'MySql' could not be found .When I click on the using MySql.Data.MySqlClient; line, Dnspy leads me to an empty page. Mysql.Data is shown in the references folder but there is nothing inside it.

Solution

  • That is an external reference, not in the .exe itself but looks like MySql connector classes.

    I have downloaded MySql.Data.dll from nuget and put it into the same folder and restarted the Dnspy. It worked.
