      We are thinking about moving from database first, to code first, with our new projects.

          But how many times has someone updated one, and forgot to update the other? At least with auto-generation, you're one click away from regenerating. With code first, you need to sit down and verify every recent change to ensure it has been incorporated.

                  Light roast (mild flavor), has more caffeine than manly, dark roast. Just saying. :-D Although, I prefer the flavor of a medium roast to a Sumatra, etc..

                          I still prefer to design the database the traditional way, but the migrations that code first uses are pretty cool.

                            Frack no. It's the epitome of taking a very bad idea and following it ad absurdum.

                                Here is an example click[^] It can generate scripts and apply them to the database based on changes made to the POCO classes used.

                                  I do indeed. You need to spend some time ensuring that your entity changes will produce the database design you're expecting (e.g. table-per-class, table-per-hierarchy etc...) and you may want to write some helpers to make adding things like indexes a bit easier but otherwise I've found it to be a very neat way of doing things. One thing to consider though is your initial database creation, for this I'd suggest either having a script to create the database and manage the configuration of it (not my preferred) or create a Database Project and output a DACPAC (much better and has better deployment options if you're using MS SQL Server). The reason for this is that if you use something like EF migrations then you'll get default database settings and sizings when it's created which you may not want, using a DACPAC means you get control over things like collation and recovery modes.

                                    Hm, how does your heart manage with all that caffeine? I'm genuinely curious as I've tried drinking more coffee but it only made my heart beat faster, my mind was still very interested in sleeping. :) Or maybe I haven't developed a tolerance yet - haven't been drinking coffee regularly for too long.

                                      I was raised with manual DB creation and then creating code that accesses the DB. This worked well with the waterfall model, where (theoretically) no changes would appear after planning and design (on paper) were over. But in recent years, as things became more "agile" (read: people do not want to make decisions, people want to change their mind very often, people just lack knowing the full story) I started to change my mind. We had lots of problems in our application when we were adding fields to an already existing complex DB and then implementing the handling code. Sometimes datatypes were wrong. Sometimes fieldnames were misspelled etc especially when the change was not implemented by just only one person. Another strong point for code-first entities design was the thing with SVN: While we had good practice already with versioning our code, the DB was hard to track in SVN. Ultimately people started to checkin binary backups from SQL Server, but you could not diff them etc. With code-first we now have a singular, unique description of the Db in Plaintext, with matching datatypes and compile-time error checks. Our test cycles are much easier now. BR Florian

                                        what about different flavours of coffee? does it help? Its normal coffee first (medium don't want to shock the heart to early, got work to do), then mid-morning, may be a orange flavoured coffee or cameral. Just received some Chocolate Mint, but not sure I like this one.
