System.Net.Http.WinHttpHandler
Returns a string message for the specified Win32 error code.
Gets a known header name string from a matching char[] array segment, using a case-sensitive
ordinal comparison. Used to avoid allocating new strings for known header names.

earlier versions.

Callers can apply a to a field, property or method
and use that field, property or method in a conditional or assert statements in order to safely call platform specific APIs.
The type of the field or property should be boolean, the method return type should be boolean in order to be used as platform guard.
Annotates the custom guard field, property or method with an unsupported platform name and optional version.

Gets the task represented by the IAsyncResult.
Throws an argument exception for the invalid .
Provides a simple IAsyncResult that wraps a Task.
We could use the Task as the IAsyncResult if the Task's AsyncState is the same as the object state,
but that's very rare, in particular in a situation where someone cares about allocation, and always
using TaskAsyncResult simplifies things and enables additional optimizations.

Gets or sets the scope of the code that is relevant for the attribute.
The Scope property is an optional argument that specifies the metadata scope for which
the attribute is relevant.
Gets or sets a fully qualified path that represents the target of the attribute.
The property is an optional argument identifying the analysis target
of the attribute. An example value is "System.IO.Stream.ctor():System.Void".
Because it is fully qualified, it can be long, particularly for targets such as parameters.
The analysis tool user interface should be capable of automatically formatting the parameter.
Gets or sets an optional argument expanding on exclusion criteria.
The property is an optional argument that specifies additional
exclusion where the literal metadata target is not sufficiently precise. For example,
the cannot be applied within a method,
and it may be desirable to suppress a violation against a statement in the method that will
give a rule violation, but not against all statements in the method.
Gets or sets the justification for suppressing the code analysis message.
