Can't use mysql on mono Linux OpenSuse

[mostafa alshrief]

hello every one,
i'm trying to build a simple console application using Mono framework and a MySQL server as a backend data base,

i'm using MySQL Connector/Net 6.4

==================================================================================
when i try to reference the assembly from an absolute dir i get the following error from the gmsc compiler :
Missing method .ctor in assembly /home/mostafa/projects/c-sharp/mysql_test/mysql.data.dll, type System.Security.SecurityRulesAttribute
Can't find custom attr constructor image: /home/mostafa/projects/c-sharp/mysql_test/mysql.data.dll mtoken: 0x0a00002b

when i try to reference the assembly from the GAC i get the following error :
error CS0006: cannot find metadata file `MySql.Data'
