I am looking for a solid tutorial on using the Entity Framework with POCO (ie. not using the designer) using MySQL as the back-end. I am looking for something that is semi-in-depth covering stuff like attributes (like how to map a database table/field name to a class/field name that is different). Also I am looking for C#, not VB. Does anyone know of any such tutorials?
For EF with MySQL, check this other question:
Using MySQL with Entity Framework
Basically you need to get a connector from MySQL and work normally from there.
For POCOs, either you do code the mappings, and then I assume you use EF 4 Futures CTP 5 recently releaed, or you use the designer, and this is what is normally in EF 4.
If the meant is default EF 4 POCO support, or POCO template in EF CTP5, those should be helpful reads:

If you are using the code only way, you need to realize it's pre-release and has some issues when working with.
