Please provide a succinct description of the issue.

Repro steps

Provide the steps required to reproduce the problem

1. Create a new timer triggered function project (.net 6)

2. Rename TimerInfo parameter to underscore (_)

Expected behavior

I expect this to work. I could not find any naming rules for timerInfo parameter name, so it would be nice to know why this is a limitation.

Actual behavior

Runtime error: The 'Function1' function is in error: The binding name _ is invalid. Please assign a valid name to the binding.

Hi @anton-gustafsson We are discussing this internally and let you know about the findings soon!

Hi @anton-gustafsson It is recommended that parameter name should be something meaningful. It is allowed that name can start with underscore. It is not supporting the "underscore" as a parameter name. You may want to go through ValidateBinding
