Old Code (v11.x):

services.AddMediatR(typeof(CreateProjectCommand).Assembly);

New Code (v13.x):

services.AddMediatR(cfg =>
{
    cfg.LicenseKey = configuration["MediatR:LicenseKey"];
    cfg.RegisterServicesFromAssembly(typeof(CreateProjectCommand).Assembly);
});

2. License Key Configuration (appsettings.Development.json)

File: C:\Users\yaoji\git\ColaCoder\product-master\colaflow-api\src\ColaFlow.API\appsettings.Development.json

Added Configuration:

Next Steps for Users

1. Configure License Keys

Users must configure their purchased license keys before running the API. See LICENSE-KEYS-SETUP.md for detailed instructions.

Quick Setup (User Secrets - Recommended):

cd colaflow-api/src/ColaFlow.API

# Set MediatR license key
dotnet user-secrets set "MediatR:LicenseKey" "your-actual-mediatr-license-key"

# Set AutoMapper license key (if using AutoMapper)
dotnet user-secrets set "AutoMapper:LicenseKey" "your-actual-automapper-license-key"

Alternative Setup (appsettings.Development.json):

1. Open colaflow-api/src/ColaFlow.API/appsettings.Development.json
2. Replace YOUR_MEDIATR_LICENSE_KEY_HERE with your actual license key
3. Replace YOUR_AUTOMAPPER_LICENSE_KEY_HERE with your actual license key

2. Verify API Startup

cd colaflow-api/src/ColaFlow.API
dotnet run

Expected Result:

• API starts without license warnings
• No errors in console logs

3. Database Migration (If Needed)

cd colaflow-api/src/ColaFlow.API
dotnet ef database update

Rollback Instructions (If Needed)

If issues arise, you can rollback by reverting these changes:

1. Revert Package References

Edit the three .csproj files and change:

<!-- Rollback to v11.x/v12.x -->
<PackageReference Include="MediatR" Version="11.1.0" />
<PackageReference Include="MediatR.Extensions.Microsoft.DependencyInjection" Version="11.1.0" />
<PackageReference Include="AutoMapper" Version="12.0.1" />
<PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="12.0.1" />

2. Revert Registration Code

In ModuleExtensions.cs:

services.AddMediatR(typeof(CreateProjectCommand).Assembly);

3. Restore and Build

dotnet clean
dotnet restore
dotnet build
