Introduced `ApiKeyAuthOptions` for API key configuration,
including a `Key` property and `SectionName` for binding.
Updated `ApiKeyAuthMiddleware` to validate the `X-Api-Key`
header against the configured API key.
Added conditional middleware application in `Program.cs`
based on the presence of a configured API key. Bound the
`ApiKey` section in `appsettings.json` and
`appsettings.Development.json` to store the API key, with
a default value of `null`. This improves security and
centralizes API key management.
This commit introduces the initial setup for the DigitalData.TaskFlow solution:
- Added `DigitalData.TaskFlow.sln` to organize the project structure into `src`, `presentation`, `core`, and `infrastructure` folders.
- Created `DigitalData.TaskFlow.API` project targeting .NET 8.0 with nullable reference types and Swagger/OpenAPI support.
- Added `Program.cs` to configure the ASP.NET Core application with services, middleware, and Swagger UI.
- Added `launchSettings.json` for development profiles and environment variables.
- Added `appsettings.json` and `appsettings.Development.json` for logging and configuration.
