What: Lets you immediately add the necessary imports or using directives for copy-and-pasted code.
When: It's common practice to copy code from different places in your project or other sources and paste it in to new code. This Quick Action finds missing imports directives for copy-and-pasted code and then prompts you to add them. This code fix can also add references from project to project.
Why: Because the Quick Action automatically adds necessary imports, you don't need to manually copy the using
directives that your code needs.
