How to Run:

Update Configuration

Database
  • Update Connection Strings:

    Project Configuration File Configuration Key
    ClassifiedAds.Migrator appsettings.json ConnectionStrings:ClassifiedAds
    ClassifiedAds.BackgroundServer appsettings.json ConnectionStrings:ClassifiedAds
    ClassifiedAds.IdentityServer appsettings.json ConnectionStrings:ClassifiedAds
    ClassifiedAds.WebAPI appsettings.json ConnectionStrings:ClassifiedAds
    ClassifiedAds.WebMVC appsettings.json ConnectionStrings:ClassifiedAds
  • Run Migration:

    • Option 1: Using dotnet cli:
      • Install dotnet-ef cli:
        dotnet tool install --global dotnet-ef --version="5.0"
        
      • Navigate to ClassifiedAds.Migrator and run these commands:
        dotnet ef migrations add Init --context AdsDbContext -o Migrations/AdsDb
        dotnet ef migrations add Init --context ConfigurationDbContext -o Migrations/ConfigurationDb
        dotnet ef migrations add Init --context PersistedGrantDbContext -o Migrations/PersistedGrantDb
        dotnet ef database update --context AdsDbContext
        dotnet ef database update --context ConfigurationDbContext
        dotnet ef database update --context PersistedGrantDbContext
        
    • Option 2: Using Package Manager Console:
      • Set ClassifiedAds.Migrator as StartUp Project
      • Open Package Manager Console, select ClassifiedAds.Migrator as Default Project
      • Run these commands:
        Add-Migration -Context AdsDbContext Init -OutputDir Migrations/AdsDb
        Add-Migration -Context ConfigurationDbContext Init -OutputDir Migrations/ConfigurationDb
        Add-Migration -Context PersistedGrantDbContext Init -OutputDir Migrations/PersistedGrantDb
