Dependencies

Fax depends on the WCF client framework to compile, on the external SAIFFaxService service to function at runtime, and on SAIF.Services.WCF — a library consumed as documented at SAIF.Services.Web.Proxies overview — as its in-repository caller.

Internal dependencies

Project	In this repository	Purpose	Usage
SAIF.Services.Web.Proxies	Yes	Owns the generated proxy and the FaxServiceProxy wrapper	Compiled into the proxy and wrapper that construct and invoke FaxServiceSoapClient
SAIF.Services.WCF	Yes	Consumes the wrapper through FaxService, and references SAIF.Services.Web.Proxies as a project reference	Constructs FaxServiceProxy and calls SendFax once per recipient

External dependencies

Framework components

Component	Assembly	Purpose	Usage
System.ServiceModel	System.ServiceModel.dll	Supplies ClientBase<T>, BasicHttpBinding, and EndpointAddress used by the generated proxy and the wrapper	Used at construction and invocation of FaxServiceSoapClient
System.Xml	System.Xml.dll	Supplies XmlDictionaryReaderQuotas used to raise MaxArrayLength in the wrapper's binding	Used when the wrapper builds its BasicHttpBinding

NuGet packages

This proxy requires no NuGet package; it depends only on framework assemblies.

Assembly references outside the package system

No assembly is referenced outside the package system.

Transitive dependencies

No transitive dependency is evidenced from source.

Service dependencies

Service	Endpoint	Documented by this run	Documentation	Operations used	Usage
SAIFFaxService	http://websvcprod/webservices/SAIFFaxService/faxservice.asmx	No	SAIFFaxService†	Send	Called once per recipient to deliver a fax document

Configuration dependencies

Setting	Source	Required at	Usage
faxSoapServiceUrl	Services/SAIF.Services.WebApi/EnvironmentApi/App_Data/environments.xml	First call	Resolved through EnvironmentConfigKeys.FaxSoapServiceUrl, a constant not defined in this repository's source*, and used to build the EndpointAddress passed to FaxServiceProxy

Dependency risks and notes

Dependency	Risk	Impact if unavailable	Usage
SAIFFaxService	No retry, no timeout override, and no cancellation at either layer	Fax delivery for the affected recipient fails, and for a multi-recipient request, later recipients in the loop are never attempted	Called once per recipient by FaxService.SendFax
