Dnspy can't compile MySql.Data

Question

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.

That is an external reference, not in the .exe itself but looks like MySql connector classes. You can look at it [at MySQL documentation](https://dev.mysql.com/doc/dev/connector-net/8.0/html/N_MySql_Data_MySqlClient.htm) — Cleptus, Oct 06 '19 at 16:22
Thank you for your advice. I have put the mySql.data.dll in to the same folder and restarted the Dnspy. It worked. — Tamer Yeşildağ, Oct 06 '19 at 16:29

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