For This to work on your machines, you will have to do two things. Follow the Visual Studio section in this link
- Install Azure-functions-core-tools@core package is installed using npm.
- Create a debug profile and setup as shown below and use that profile while launching it from visual studio.

I got same thing and fixed it by updating Azure Functions and Web Jobs Tools.
Note that as per the change list here, support for remote debugging of V2 functions was only enabled in 15.0.31201.0, and was granted a bug fix in 15.0.40108.0. https://github.com/Azure/Azure-Functions/blob/master/VS-AzureTools-ReleaseNotes.md
So, go into Tools and Extensions, see what version of the Azure Functions and Web Jobs Tools you have, and if it's older than 15.0.40108.0, upgrade it.

got the same error with a brand new Function project in Visual Studio 2017. After getting the prompt from Visual Studio to upgrade Azure Function to v1.0.7 , I got rid of the error
