I am using BLToolKit (ver. 4.3.2.0) and MySql Connector (BLToolkit.Data.DataProvider.MySql.4 of version 4.3.2.0) from NuGet. When I run my web.app in the mono-environment all work perfectly. But on the IIS I get an exception:

FileLoadException: Could not load file or assembly 'MySql.Data, Version=6.9.7.0, Culture...

What is wrong?

UPD: also I used the MySql.Data (from NuGet), version 6.9.8.0

  • I still don't know, what is the matter. I just removed all, and installed all from the scratch. Oh, and it is very important: nor MSVS, either nuget console couldn't handle its own references, saved in the project.. References and nuget packages are often contradict each other. It is [**SO SWEEET**] for developers... Oh, I like and I really love to solve such conflicts manually – maxkoryukov Jun 07 '16 at 19:49

Just a guess: Is the corresponding assembly in the same folder as your program (should be a library file like "MySql.dll" or "MySql.Data.dll")?

EDIT: This problem has been reported previously: Could not load file or assembly 'MySql.Data, Version=6.2.2.0

I had the samen problem and resolved it with a copy of the previous version. - Download the version you need from https://downloads.mysql.com/archives/c-net/ - install the connector on a PC (not the one you are using, it won't install - copy the folder MySQL Connector Net 6.9.5 from C:\Program Files (x86)\MySQL to the same folder on your PC. - In Visual studio: remove the MySQL.Data-reference. - Add the reference again using 'Addreference / Browse' - Choose MySQL.Data.dll in the folder C:\Program Files (x86)\MySQL\MySQL Connector Net version\Assemblies\v4.5
