MappedDiagnosticsLogicalContext Class

Note: This API is now obsolete.

Obsolete and replaced by ScopeContext with NLog v5. Mapped Diagnostics Logical Context (MDLC) is a dictionary of keys and values. Stores the dictionary in the logical thread callcontext, and provides methods to output dictionary values in layouts. Allows for maintaining state across asynchronous tasks and call contexts.

Public NotInheritable Class MappedDiagnosticsLogicalContext

You do not need to declare an instance of a static class in order to access its members.

[<AbstractClassAttribute>]
[<SealedAttribute>]
[<ObsoleteAttribute("Replaced by ScopeContext.PushProperty or Logger.PushScopeProperty using ${scopeproperty}. Marked obsolete on NLog 5.0")>]
type MappedDiagnosticsLogicalContext =  class end

The MappedDiagnosticsLogicalContext type exposes the following members.

	Get(String)	Obsolete. Gets the current logical context named item, as String.
	Get(String, IFormatProvider)	Obsolete. Gets the current logical context named item, as String.
	GetNames	Obsolete. Returns all item names
	GetObject	Obsolete. Gets the current logical context named item, as Object.
	Remove	Obsolete. Removes the specified item from current logical context.
	Set(String, Object)	Obsolete. Sets the current logical context item to the specified value.
	Set(String, String)	Obsolete. Sets the current logical context item to the specified value.
	SetT(String, T)	Obsolete. Sets the current logical context item to the specified value.
	SetScoped(IReadOnlyListKeyValuePairString, Object)	Obsolete. Updates the current logical context with multiple items in single operation

Remarks

Ideally, these changes should be incorporated as a new version of the MappedDiagnosticsContext class in the original NLog library so that state can be maintained for multiple threads in asynchronous situations.
