问题
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.
EDIT: Found the fix. Under Tools > Options... > Text Editor > C# > IntelliSense, I had to uncheck 'Show items from unimported namespaces (experimental)'.
