Use model first approach with Entity Framework and allow changes to deployed database/ model to be done automatically based on the changes in the model. Automatic schema difference script generation to allow smooth migrations.
Is there a way to perform migrations in model first EF6? I can see code first migrations topics all over, but nothing much on Model First.
Options I saw so far:
As far as I know there still is no automatic migration for Entity framework model first.
Our approach is:
We first used Open DB diff for our model first migrations. After that we switched to Redgate's SQL compare because it produced more reliable migrations . In our experience DbDiff produced a lot of unnecessary SQL because it bothers with the order that columns are in, and has some other issues like foreign keys constantly being dropped and re-added. Aside from that it still did the job fine, but we had to do a lot of double checking on its generated SQL.
