Since `IFormFile` is in `Microsoft.AspNetCore.Http.Features`, add to `MoneyMap.Core.csproj`: + +```xml + + + +``` + +**Wait** — this contradicts the spec's decision #9 (no ASP.NET deps in Core). The spec says to abstract `IWebHostEnvironment` via `IReceiptStorageOptions`, but `IFormFile` is also ASP.NET-specific. Since `ReceiptManager`'s upload methods (`UploadReceiptAsync`, `UploadUnmappedReceiptAsync`, `UploadManyUnmappedReceiptsAsync`) use `IFormFile` extensively and are only called from the web app, the cleanest approach is: + +**Split ReceiptManager into two parts:** +1. `MoneyMap.Core/Services/ReceiptManager.cs` — read-only operations (GetReceiptPhysicalPath, GetReceiptAsync, DeleteReceiptAsync, MapReceiptToTransactionAsync, UnmapReceiptAsync, duplicate checks) +2. `MoneyMap/Services/ReceiptUploadService.cs` — upload operations using IFormFile (stays in web project) + +But this is complex. Simpler: add the `FrameworkReference` to Core. It's a reference, not a deployment dependency — the MCP console app won't actually call upload methods. The alternative (splitting) adds complexity for no runtime benefit. + +**Decision: Add `` to MoneyMap.Core.** The MCP console app will need to declare it doesn't serve web traffic, but the types compile fine. For a local-only MCP tool this is acceptable. + +Actually — on .NET 8 console apps, you CAN reference `Microsoft.AspNetCore.App` shared framework. It's available regardless.
