JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.USAGE.CA2256 : All members declared in parent interfaces must have an implementation in a DynamicInterfaceCastableImplementation-attributed interface (C#)

Summary

Types attributed with 'DynamicInterfaceCastableImplementationAttribute' act as an interface implementation for a type that implements the 'IDynamicInterfaceCastable' type. As a result, it must provide an implementation of all of the members defined in the inherited interfaces, because the type that implements 'IDynamicInterfaceCastable' will not provide them otherwise.

This check corresponds to Roslyn rule CA2256. For full rule details, see the Microsoft website: CA2256.
