DDDReference

An example solution where multiple layers are organized in their own project. Notable, an Infrastructure project that contains persistence-related responsibilities, a Domain project with entities and their logic, and a an Api project (presentation) as startup.

This an error with Entity Framework attempting initial creation of database via migrations. To reproduce:

dotnet ef migrations add InitialCreate --startup-project Api --project Infrastructure
dotnet ef database update --startup-project Api --project Infrastructure

The error:

System.InvalidOperationException: An error was generated for warning 'Microsoft.EntityFrameworkCore.Migrations.PendingModelChangesWarning': The model for context 'AccountSqliteDbContext' has pending changes. Add a new migration before updating the database. This exception can be suppressed or logged by passing event ID 'RelationalEventId.PendingModelChangesWarning' to the 'ConfigureWarnings' method in 'DbContext.OnConfiguring' or 'AddDbContext'.
