To understand the relationship in the Entity Framework Code First approach, we create an entity and define their configuration using the Fluent API. We will create two class library projects, one library project (EF.Core) has entities and another project (EF.Data) has these entities configuration...
As you said we can copy the whole string in a separate text file and we can paste it in the command line whenever it is needed but all users may not have less than or equal to 120 tables in my case it will be okay to prepare a string for the first time. If one has more tha...
So a "DB First" approach saves everyone time because I point at the already existing tables and say "create stuff out of that." Done. In EF 5 this takes pretty much no time to get up and running. With the early "code first", I couldn't do that, thus using it at all was a ...

and then the DBA tells you that your table needs to be normalized as it is too wide and inefficient and hands you a list of new tables to use instead of pulling from the one table you did in a code first approach as they are about to change the table definition for performance ...
The Code First approach enables you to define an entity model in code, create a database from the model, and then add data to the database. MySQL Connector/NET is compatible with multiple versions of Entity Framework Core. For specific compatibility information, see Table 7.2, “Connector/NET...
