[Visual Studio] Unable to start debugging or run Function code using VS Tooling (console crashes)

Unable to start debugging using Visual Studio Tooling for Azure Functions Preview.

Repro steps

Start debugging my newly created Function project in Visual Studio. Command line arguments of the command prompt started by VS2015: C:\Users\dev\AppData\Local\Azure.Functions.Cli\1.0.0-beta.8\func.exe host start --port 7071 & pause

Expected behavior

Starting project and debugger attaches to my function.

Actual behavior

Console crashes, call stack:

@lindydonna The dots in the project name have no effect. I kept the dots in the filename, but removed the dots from the folder name in which the project was and it started working in order to have it working.

[MisinformedDNA]

I think they should be centralized under one name. We don’t need WebJobs and Functions. They are practically the same.
