Asp conenction error when the database is updating Freechatlove
It’s terrible for deployment and maintenance and it limits your flexibility and it’s just not a good idea (Circle slash hard-coded connection strings.) The problem is that if you get rid of the On Configuring() method, you’ll get an error when you try to run your EF Core database migration. Remove that method, and run “dotnet ef database update”. allows you to put the logic of creating instances of your Db Context into a type-safe class that follows a pattern that is known and usable by your code and the tooling of “dotnet ef”, Visual Studio, and Visual Studio Code. (Remember, when writing unit tests, always start with a failing test.) The “Copy always” on the in the Benday. Api project was causing that to get copied into the run directory for the unit tests. I needed to have separate configs for the API, Web, and Test projects.
It gives you a nice, clean way to separate the persistence details of your Db Context from the construction and configuration details for your Db Context. That was ok for right now but this was going to cause problems because my Benday. Tests project would forever be fighting the Benday. The essence of the problem is that IDb Context Factory was going to be called from multiple environments with multiple configurations and my basic implementation didn’t know how to handle that. NET Core project isn’t going to use this IDb Context Factory and that’s fine.) I ended up with two public methods on my IDb Context Factory implementation.
This pattern fits nicely with the SOLID principles and Separation of Concerns and keeps your code organized. Create(Db Context Factory Options options) is the method that gets called by the “dotnet ef database update” command when you deploy your migrations.
In my implementation of IDb Context Factory, I wanted to be able to read my connection strings from and from environment variables. It assumes that your file will be near the code and the csproj file. This is the key item that keeps this API project from messing up the runtime in all the other projects.
