# SAIF.Services.Web.Proxies dependencies

SAIF.Services.Web.Proxies has a single same-repo project reference (SAIF.SAIFCode.Core, for its contract DTOs), two directly-used SAIF framework NuGet packages, several packages.config entries with no authored usage, and 12 consumed SOAP/REST services reached only through generated clients and one hand-rolled Google Maps REST client; it is consumed in-repo by SAIF.Services, SAIF.Services.Common, and SAIF.Services.WCF.

## Internal dependencies

| Dependency | Reference Type | Usage |
| --- | --- | --- |
| [SAIF.SAIFCode.Core](../saif-saifcode-core/overview.md) | Project Reference | Supplies the SAIF.Core contract DTOs mapped by every wrapper (`SAIF.Core.Contracts` `Contact`, `Address`, `PhoneNumber`, `PersonName`, `ApplicationExceptionDetail`; `SAIF.Core.Contracts.CertifiedLabel`; `SAIF.Core.Contracts.Core.DistanceResults`; `SAIF.Core.Contracts.Documents.FaxInfoClass`; `SAIF.Core.Services.Documents` types; the `PlexMode`, `ScaleMode`, and `PaperTray` enums) |
| SAIF.Framework.Core | NuGet Package | Provides `IEnvironmentService` and `ILogService` (namespace `SAIF.Core.Services`) and the `Enforce` argument-guard helper, used across every wrapper's construction and method guards* |
| SAIF.Framework.Common | NuGet Package | Provides `SAIF.Common.Extensions` (`IsNullOrEmpty`, `Truncate`, `IsNull`), used to truncate SimpleCertifiedMail label fields* |
| SAIF.Web.API.Clients | NuGet Package | Referenced in `packages.config`; no authored usage found (no `JsonHttpClient`/`ClientInfo` in this library) |
| SAIF.HashUtil | NuGet Package | Referenced in `packages.config`; no authored usage found |

## External dependencies

| Dependency | Version | Usage |
| --- | --- | --- |
| Autofac | 3.5.2 | Referenced in `packages.config`; no authored usage found (no `ContainerBuilder` registrations in this library) |
| FluentValidation | 5.5.0.0 | Referenced in `packages.config`; no authored usage found |
| log4net | 2.0.5 | Referenced in `packages.config`; no authored usage found |
| Newtonsoft.Json | 8.0.3 | Referenced in `packages.config`; no authored usage found |
| RestSharp | 106.12.0 | Referenced in `packages.config`; no authored usage found |

Two third-party binaries are referenced by `HintPath` rather than NuGet: `Libs/ThirdParty/CallRex/CallRex.Utilities.dll` and `CallrexAPIUtilities.dll`. No authored usage of either was found.

**Consumed SOAP client proxies.** This library hosts 11 of the 12 SOAP/WCF client proxies consumed by SAIF and its hosts (the 12th, CleanAddressSvc, is hosted in `SAIF.Services` as a web reference). Each is documented separately, outside this dependency page, at `docs/clients/<proxy-slug>/`:

| Proxy | Slug | Generated client |
| --- | --- | --- |
| ActiveDirectory | `activedirectory` | `clsADServicesSoapClient` (internal), wrapped by `ActiveDirectoryServiceProxy` |
| CallRex | `callrex` | `ClientServiceClient` / `ClientAccessPolicyClient` (public); no authored wrapper |
| CallRexState | `callrexstate` | `AgentStateServiceClient` (duplex, public) / `ClientAccessPolicyClient` (public); no authored wrapper |
| DbConnection | `dbconnection` | `ConnectInfoSoapClient` (internal), wrapped by `Legacy.DbConnectionServiceProxy` |
| Document | `document` | `clsGenerateSoapClient` (internal), wrapped by `DocumentServiceProxy` |
| Fax | `fax` | `FaxServiceSoapClient` (internal), wrapped by `FaxServiceProxy` |
| Logging | `logging` | `clsWSLoggingSoapClient` (internal), wrapped by `LoggingServiceProxy` |
| PDFService | `pdfservice` | `PDFServiceClient` (internal), wrapped by `PdfServiceProxy` |
| SimpleCertifiedMail | `simplecertifiedmail` | `ADSAPISoapClient` (public), wrapped by `SimpleCertifiedMailServiceProxy` |
| SMTP | `smtp` | `clsSAIFMessageSoapClient` (internal); no authored wrapper, unreachable |
| WorkCalendar | `workcalendar` | `SAIFDatesSoapClient` (internal), wrapped by `WorkCalendarServiceProxy` |
| CleanAddressSvc | `cleanaddresssvc` | Hosted in `SAIF.Services`, not in this library |

The Google Distance Matrix API is consumed directly by `GoogleMapsApiServiceProxy` as a hand-rolled REST/XML client over `System.Net.WebRequest`; it has no generated service reference and is not one of the 12 catalogued SOAP client proxies.

## Dependency risks and notes
- **No composition root for injected proxies.** No Autofac registration for `ISimpleCertifiedMailServiceProxy` or `IGoogleMapsApiServiceProxy` exists anywhere in this repository; the host that wires them for SAIF.Services consumers is external**.
- **Unused packages and binaries.** `SAIF.Web.API.Clients`, `SAIF.HashUtil`, `Autofac`, `FluentValidation`, `log4net`, `Newtonsoft.Json`, `RestSharp`, and the CallRex third-party DLLs have no authored usage; it is unknown whether they are required transitively (for example, by generated proxy code) or are stale**.
- **Non-secure secret retrieval.** `SimpleCertifiedMailService.Password`, `SimpleCertifiedMailService.PartnerKey`, and `googlemaps.apikey` are read with `IEnvironmentService.GetConfigSetting` rather than `GetSecureConfigSetting` (see [Configuration](configuration.md)).
- **Unreachable generated clients exposed publicly.** `CallRex.ClientServiceClient`, `CallRex.ClientAccessPolicyClient`, `CallRexState.AgentStateServiceClient`, and `CallRexState.ClientAccessPolicyClient` are `public` in the packaged assembly even though no in-repository code constructs them.
- **Plain-HTTP transport of database credentials.** `Legacy.DbConnectionServiceProxy` requests and receives Oracle/SQL Server connection strings, which contain credentials, over a default unsecured `BasicHttpBinding`; whether the transport is HTTPS depends only on the caller-supplied URL scheme.
- **Consumers.** In-repository `<ProjectReference>` consumers are `Services/SAIF.Services/SAIF.Services.csproj` (line 503), `Services/SAIF.Services.Common/SAIF.Services.Common.csproj` (line 95), `Services/SAIF.Services.WCF/SAIF.Services.WCF.csproj` (line 142), and `Tests/SAIF.Services.Tests/SAIF.Services.Tests.csproj` (line 360); `Services/SAIF.Services.WebApi/EnvironmentApi/EnvironmentApi.csproj` and `DependencyMaps/SAIF.DependencyMaps.Web.DocCenterApi` consume the packaged binary via `HintPath`, and `Web/SAIF.Web.Mvc` consumes it through the packaged `SAIF.SAIFCode.Core.2.0.22164.1` NuGet package.
