受私人保护不起作用

Question

I have a method:

private protected string SendRequest(BaseRequest request, string httpMethod, bool isPublicRequest) { ... }

BaseRequest is internal, that's why I want to use the new private protected combination.

Unfortunately I still get an error:

"Modifier 'protected' cannot be combined with 'private'"

I upgraded VS to 15.5.2 so why does it not know the new C# Features? Clean solution didn't help by the way.

Answer 1

This feature requires version 7.2.

to accomplish this:

1. Right-click on your project
2. at the bottom of the available options click Properties
3. Click on Build
4. Click on Advanced
5. Within the pop-up, change the language version to match the required version (7.2)

Also, as @Sir Rufo has mentioned in the comments section you can set this option for each configuration. Therefore changing it for all configurations would be the better option.
