## AI Coding Instructions

- Keep `Microsoft.Threading.Tasks.Extensions` managed through the `Pams.Email.csproj` NuGet dependency configuration.
- Run `dotnet restore` after changing package references or restoring the repository on a new machine.
- Verify target framework compatibility before updating this package, especially when changing task-related APIs.
- Do not reference the package directly from TypeScript or JavaScript; it is resolved as part of the .NET project build.
