Architecture¶

This repository reaches SAIFDates† only through the authored WorkCalendarServiceProxy wrapper, which builds a default BasicHttpBinding() in code and passes a caller-supplied URL to the generated, internal SAIFDatesSoapClient; no repository source constructs WorkCalendarServiceProxy itself.

Proxy mechanism¶

Aspect	Finding
Mechanism	Service Reference (svcutil)
Proxy type	`SAIFDatesSoapClient` (`internal`)
Base type	`System.ServiceModel.ClientBase<T>`
Contract type	`internal interface SAIFDatesSoap`
Constructed in	`WorkCalendarServiceProxy` constructor (`Services/SAIF.Services.Web.Proxies/WorkCalendarServiceProxy.cs:12-19`) — the wrapper itself has no in-repository caller
Binding configured in	Code — `new BasicHttpBinding()` with every default
Address supplied by	Constructor argument (`serviceUrl`) passed to `WorkCalendarServiceProxy`; the generated `<client><endpoint>` in `app.config` is bypassed

Architecture diagram¶

The following diagram visualizes how a call would reach the remote service if WorkCalendarServiceProxy were constructed and called.

Hand-written wrapper¶

Field	Value
Type	`WorkCalendarServiceProxy`
Source	`Services/SAIF.Services.Web.Proxies/WorkCalendarServiceProxy.cs`
Visibility	`public`
Implements	`IDisposable`
Responsibility	Builds the binding and endpoint address, constructs the generated client, and passes each of the four operations through unchanged
Proxy lifetime	Per `WorkCalendarServiceProxy` instance

Configuration applied	Value	Source
`BasicHttpBinding` security mode	`None` (default — not set explicitly)	`WorkCalendarServiceProxy.cs:16-19`
Transport client credential	None configured	`WorkCalendarServiceProxy.cs:16-19`
`MaxReceivedMessageSize`	`65536` (default — not raised)	`WorkCalendarServiceProxy.cs:16-19`
`MaxBufferSize`	Not set — binding default applies	—
Timeouts	None set — binding defaults apply	`WorkCalendarServiceProxy.cs:16-19`

Endpoint resolution¶

Environment	Address	Resolved from	Changeable without a rebuild
All	Unresolved** — the `serviceUrl` constructor argument, supplied by whoever constructs `WorkCalendarServiceProxy`; no repository source does so	`WorkCalendarServiceProxy.cs:12-19`	Yes — the address is a constructor argument, not a compiled-in literal, but no caller exists in this repository to change it

The candidate environment key workCalendarServiceUrl resolves to the same address (http://saifonline/webservices/SAIFDates/saifdates.asmx) on every track in environments.xml, but nothing in this repository reads it and passes it to WorkCalendarServiceProxy.

Lifetime and disposal¶

Aspect	Finding
Proxy lifetime	Per `WorkCalendarServiceProxy` instance
Disposal	`Close()` only — `WorkCalendarServiceProxy.cs:49-65`
Faulted-channel handling	No `Abort()` path; `Close()` on a faulted channel throws `CommunicationObjectFaultedException` and masks the original failure*
Thread safety	Not determined from source

Integration points¶

System	Type	Purpose
`SAIFDates`†	SOAP service (ASMX)	Work-day calendar lookups
