I'm using VS Code and I can't figure out if it's possible to take a class and extract an interface from it. When I google how to do this, I only find extensions for TypeScript, but I want to do this in C#.
Can VS Code extract interfaces? Knowing the shortcut would be nice for others, but I'm using a different keymap, so I'd like to know how to do this from the menu.
You may try this,
Move your cursor on the class_name that you want to extract interface. Then Ctrl + . (period) Then choose "Extract Interface" this will generate a code above the class that you want to be extracted. Then move your cursor the interface class_name Ctrl + . (period) again, then choose "Move type to the" auto-generated class name then that's it.
Hope this will help you guys and for future reference.
Not really sure if this feature was already there or got implemented afterwards, but I found this:
First, extract the interface as usual
Then you get to do this on your methods:
Note that it doesn't add necessary usings but uses namespaces instead. You can do the clean up as you like.
