阻止 VS 自动添加 using 指令

Question

I don't mind the using directives which are automatically created when the script is created. Those are fine. What I'm talking about are the using directives which are automatically generated at the top of the script while I'm coding as soon as I refer to a type which is out of scope. A pox upon the silent fiends!

To clarify, currently if I try including a type which exists in some namespace which is not yet declared as 'using' in the script, said namespace will get auto-added to the top of the script. This is undesired behavior for me.

I simply prefer to manually add my namespaces.

Answer 1

Under Tools > Options... > Text Editor > C# > IntelliSense, uncheck 'Show items from unimported namespaces (experimental)'.

Answer 2

Even I find this annoying. I was able to turn this off in VS 2022 using the following options. Hope this helps some one.

I do agree that Microsoft should give us an option to list the items from unimported namespaces but not add using statements automatically.

Answer 3

On the top of the page in Visual Studio, go to Tools > Options > Text Editor > C# > Advanced > Uncheck the option for "Add missing using directives on paste" then click OK on the bottom of the page. And then restart Visual Studio.
