Can I detect if my code is executing in an Azure worker role?

Question

I have some shared assemblies/projects that are used within Winforms apps, windows services and now Azure worker roles.

Is there any way that I can detect at runtime

Answer 1

For anyone interested, thought I would sharehow I implemented, thanks to @Sandrino Di Mattia's answer:

You can check for the presence of the RoleRoot environment variable (for Cloud Services at least):

Note that this does NOT cater for a Winforms App as I only actually required it in the end for Services - i.e. detecting between service running as

• Azure Worker Role
• Windows Service
• Console Application

This is an outline:

public static class ServiceRunner
{
    private static bool IsAzureWorker
    { 
        get { return !string.IsNullOrEmpty(Environment.GetEnvironmentVariable("RoleRoot")); } 
    }

    public static void Run(string[] args)
    {
        if (IsAzureWorker)
        {
            //Running as Azure Worker
        }
        else if (Environment.UserInteractive) //note, this is true for Azure emulator too
        {
            //Running as Console App
        }
        else
        {
            //Running as Windows Service
        }
    }
}
