ExecutionContext is null to non-function methods via IoC, alternative to ExecutionContext.FunctionAppDirectory

Question

ExecutionContext is available to functon parameters.

However, it is not available to other methods via dependency inject, including Functions\' constructor, like below:

Answer 1

Based on current documentation, ExecutionContext is only available in the scope of a request when the function method is being invoked.

[FunctionName("Car")]
public async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)]
    HttpRequest req, 
    ExecutionContext context //<--
) {

    var path = context.FunctionAppDirectory;

    //...
}

It wont be available as yet in the constructor for injection when the function class is initialized.
