The version of the Assembly you are refreencing is wrong, try re add the reference to the assembly by removing and readding

---

It seems you have a AssemblyName mismatch

One of your referenced assembly use MySql.Data version 6.3.5.0 and you also use MySql.Data but the version 6.2.3.0. (Compiler Error CS1705)

Change the referenced assembly version of MySql.Data to 6.3.5.0
