WebContextService¶

WebContextService implements the external IWebContextService contract and is activated over the WebContext route. This page documents every public operation the class exposes.

Field	Value
Service class	`SAIF.Services.WCF.Services.WebContextService`
Declared contract	`IWebContextService` — external (`SAIF.Services.WCF.Contracts`, arriving transitively via `SAIF.Framework.Core`) *
Route	`WebContext`
Source	`src/WCF/SAIF.Services.WCF.Host/Services/WebContextService.cs`
Service attributes	`[AspNetCompatibilityRequirements(RequirementsMode = Allowed)]`, `[LogErrorBehavior]`
Instancing / concurrency	WCF defaults — not overridden in source
Binding	`basicHttpBinding` (default, unnamed — no `<endpoint>` is configured for any of the six routes)
Class-level authorization	None in code
Error handling	`[LogErrorBehavior]` installs `ErrorLogErrorHandler`; see Faults and error pipeline
Operations	3
Also hosted in	—

Get¶

Retrieve and consume a stored web context.

Field	Value
Operation name	`Get`
Contract name	`Get` — override, if any, not observable because `IWebContextService` is declared in an external contracts assembly
SOAP action	Not observable — contract assembly is external
Implementing member	`SAIF.Services.WCF.Services.WebContextService.Get` (`src/WCF/SAIF.Services.WCF.Host/Services/WebContextService.cs`)
Pattern	Request/response (`IsOneWay` not observable — contract assembly is external)
Binding	`basicHttpBinding` (default, unnamed)
Authorization	None in code
Process	OP-009

Get input message¶

Part	Type	Required	Default	Purpose
`applicationName`	`string`	Yes	—	Application name portion of the context key.
`sessionId`	`string`	Yes	—	Session id portion of the context key.

Get output message¶

Field	Value
Return type	`IWebContext`
Meaning	The web context for the given application and session, then destroyed.
Empty-result behavior	A newly-created context with a fresh GUID id when no `__SAIFPID` item is stored.

Get faults¶

Fault	Declared	Raised when	Surfaced as	Detail crosses the boundary
`ArgumentNullException`	Not declared	See OP-009 process detail	Generic SOAP fault produced by The operation itself, via `Enforce`	Yes
SQL Server/NHibernate exception	Not declared	See OP-009 process detail	Generic SOAP fault produced by The `ErrorLogErrorHandler` installed by `[LogErrorBehavior]`	Yes

Get authorization¶

None in code. Access to Get rests entirely on the IIS authentication configured for the deployment variant; see Authentication and authorization.

Get side effects¶

Aspect	Finding
Records written	`WebContextItem` (read, then deleted)
Downstream calls	None
Files or messages produced	Deletes every `WebContextItem` row read for the application/session
Shared state touched	None
Repeat-call behavior	A repeat call after a successful `Get` returns a fresh context because the rows were deleted

Save¶

Replace the stored web context for an application and session.

Field	Value
Operation name	`Save`
Contract name	`Save` — override, if any, not observable because `IWebContextService` is declared in an external contracts assembly
SOAP action	Not observable — contract assembly is external
Implementing member	`SAIF.Services.WCF.Services.WebContextService.Save` (`src/WCF/SAIF.Services.WCF.Host/Services/WebContextService.cs`)
Pattern	Request/response (`IsOneWay` not observable — contract assembly is external)
Binding	`basicHttpBinding` (default, unnamed)
Authorization	None in code
Process	OP-010

Save input message¶

Part	Type	Required	Default	Purpose
`applicationName`	`string`	Yes	—	Application name portion of the context key.
`sessionId`	`string`	Yes	—	Session id portion of the context key.
`context`	`IWebContext`	Yes	—	The context whose entries are persisted.

Complex input types¶

Type	Kind	Members	Declared in
`IWebContext`	Data contract	Not enumerated — declared in an external contracts assembly **	`SAIF.Services.WCF.Contracts` / framework closure *

Save output message¶

Field	Value
Return type	void
Meaning	A successful response indicates only that the operation completed without a fault.
Empty-result behavior	Not applicable.

Save faults¶

Fault	Declared	Raised when	Surfaced as	Detail crosses the boundary
`ArgumentNullException`	Not declared	See OP-010 process detail	Generic SOAP fault produced by The operation itself, via `Enforce`	Yes
SQL Server/NHibernate exception	Not declared	See OP-010 process detail	Generic SOAP fault produced by The `ErrorLogErrorHandler` installed by `[LogErrorBehavior]`	Yes

Save authorization¶

None in code. Access to Save rests entirely on the IIS authentication configured for the deployment variant; see Authentication and authorization.

Save side effects¶

Aspect	Finding
Records written	`WebContextItem` (delete all, then insert)
Downstream calls	None
Files or messages produced	Deletes and reinserts the full `WebContextItem` set for the application/session
Shared state touched	None
Repeat-call behavior	Idempotent — replaces the full stored set each time

CreateContext¶

Construct a new in-memory web context.

Field	Value
Operation name	`CreateContext`
Contract name	`CreateContext` — override, if any, not observable because `IWebContextService` is declared in an external contracts assembly
SOAP action	Not observable — contract assembly is external
Implementing member	`SAIF.Services.WCF.Services.WebContextService.CreateContext` (`src/WCF/SAIF.Services.WCF.Host/Services/WebContextService.cs`)
Pattern	Request/response (`IsOneWay` not observable — contract assembly is external)
Binding	`basicHttpBinding` (default, unnamed)
Authorization	None in code
Process	OP-011

CreateContext input message¶

Part	Type	Required	Default	Purpose
`contextId`	`string`	No	—	Seed value for the new context's id; a blank value produces a fresh GUID instead.

CreateContext output message¶

Field	Value
Return type	`IWebContext`
Meaning	A new, unpersisted web context carrying the given or generated id.
Empty-result behavior	Not applicable.

CreateContext faults¶

Fault	Declared	Raised when	Surfaced as	Detail crosses the boundary
—	Not declared	—	—	—

CreateContext authorization¶

None in code. Access to CreateContext rests entirely on the IIS authentication configured for the deployment variant; see Authentication and authorization.

CreateContext side effects¶

Aspect	Finding
Records written	None
Downstream calls	None
Files or messages produced	None — no persistence occurs
Shared state touched	None
Repeat-call behavior	Idempotent when `contextId` is supplied; produces a new id each call otherwise

Coverage checklist¶

Public member	Documented section	Pattern
`IWebContext Get(string applicationName, string sessionId)`	`Get`	Request/response
`void Save(string applicationName, string sessionId, IWebContext context)`	`Save`	Request/response
`IWebContext CreateContext(string contextId)`	`CreateContext`	Request/response

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
