best practices for 'The connection string is empty' guide in ASP.NET Core with Entity Framework?
I'm performance testing and I'm working through a tutorial and I'm currently working on an ASP.NET Core 6.0 application using Entity Framework Core for data access. I've set up my DbContext and connection string in the `appsettings.json` file, but I'm working with a `System.InvalidOperationException: The connection string is empty.` behavior when trying to run my migrations. Here’s the relevant part of my `appsettings.json`: ```json { "ConnectionStrings": { "DefaultConnection": "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;" } } ``` In my `Startup.cs`, I have configured the services like this: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddDbContext<MyDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); } ``` I've confirmed that the `appsettings.json` is set to copy to the output directory, and I've checked that the connection string is correct. However, when I run the command to apply migrations, I see the behavior mentioned above. One thing I noticed is that when I log `Configuration.GetConnectionString("DefaultConnection")` just before the options configuration, it outputs an empty string. I've also tried adding `app.UseDeveloperExceptionPage();` in the `Configure` method to get more detailed behavior information, but it still doesn’t provide any insight into why the connection string is not being read. Has anyone encountered this scenario, or can someone point out what I might be missing? Has anyone dealt with something similar? My team is using Csharp for this microservice. Is there a simpler solution I'm overlooking?
