The Deprecation Warning: VMware officially deprecated the C# client after vSphere 6.0. With vSphere 6.5 and later, only the HTML5 (Web Client) and the Flash-based Web Client were supported. Consequently, VMware does not list vSphere Client 5.5 as “compatible” with Windows 11 – a fact we need to work around.
