# Dependencies

## Upstream (what the proxy depends on)

| Dependency | Kind | Evidence |
| --- | --- | --- |
| `System.ServiceModel` (`ClientBase<T>`, custom binding, binary message encoding) | .NET Framework assembly | `Reference.cs:19989`; `app.config:34-37` |
| `System.Runtime.Serialization` (DataContract types) | .NET Framework assembly | Generated types in `Reference.cs` |
| `CallRex.Utilities.dll` | Third-party binary, referenced but unused by source | `Services/SAIF.Services.Web.Proxies/SAIF.Services.Web.Proxies.csproj:57-62`; `Libs/ThirdParty/CallRex/CallRex.Utilities.dll` |
| `CallrexAPIUtilities.dll` | Third-party binary, referenced but unused by source | `SAIF.Services.Web.Proxies.csproj:57-62`; `Libs/ThirdParty/CallRex/CallrexAPIUtilities.dll` |
| Remote `` `ClientService` † `` (CallRex) | External SOAP service, hosted outside this repository | `app.config:61,66`; `Reference.svcmap` (metadata source `http://callrexprod:8002/mex`) |

The remote service is a third-party CallRex call-recording platform; its internal implementation is unknown** and outside this run's scope (`soapServiceHosts` is empty — this repository hosts no SOAP services).

## Downstream (what depends on the proxy)

| Consumer | Relationship | Evidence |
| --- | --- | --- |
| `SAIF.Services.Web.Proxies` | Owning project; compiles the generated `ClientServiceClient` / `ClientAccessPolicyClient` into its assembly | `Services/SAIF.Services.Web.Proxies/SAIF.Services.Web.Proxies.csproj` |
| `SAIF.SAIFCode.Core` NuGet package | Packages `SAIF.Services.Web.Proxies.dll`; because the generated clients are `public`, external package consumers *could* construct and call them* | `Core/SAIF.Core/SAIF.SAIFCode.Core.nuspec:75-76` |
| No in-repo caller | No source file in this repository references `ClientServiceClient`, `ClientAccessPolicyClient`, or the `CallRex` namespace outside the generated `Service References/` folder | Repository-wide search (see [Consumption](consumption.md)) |

`SAIF.Services.Web.Proxies` itself is documented at [its overview](../../libraries/saif-services-web-proxies/overview.md).

## Related proxy

`CallRexState` (duplex `AgentStateService`) is a separate generated proxy on the same `callrexprod` host, analyzed and documented independently — see [CallRexState](../callrexstate/index.md).

## Packaging

| Artifact | Location |
| --- | --- |
| Compiled assembly | `SAIF.Services.Web.Proxies.dll`, packaged into NuGet `SAIF.SAIFCode.Core` |
| Package manifest | `Core/SAIF.Core/SAIF.SAIFCode.Core.nuspec:75-76` |
