This extension method has a constant time complexity. Before v2021.2 this method used to be an extension method but with v2021.2 NDepend compiles to net472. Thus this method collided with the Enumerable.Append() introduced within net471. Some default rules used this method in a non-extension way so we made it as a non-extension method.
Requirements
Target Platforms: Windows 11, 10, 8, 7 and Linux, MacOS with net8.0, net7.0 or net6.0 installed
