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

Like you say, adding references to all your end-products is not the way to go. I would say this is a problem solved very easily using Dependency Injection.

Define an interface which yields this information (in a shared assembly):

public enum DeploymentType { WinForms, WinServices, Azure }

public interface IWhatDeploymentAmIUsing {
    DeploymentType DeploymentType { get; }
}

And create a class that implements this interface.

WinForms (in your winforms project):

public class WinFormDeploymentType : IWhatDeploymentAmIUsing {
    public DeploymentType DeploymentType { get { return DeploymentType.WinForms; } }
}

WinServices (in your windows service project):

public class WinServicesDeploymentType : IWhatDeploymentAmIUsing {
    public DeploymentType DeploymentType { get { return DeploymentType.WinServices; } }
}

Azure (in your azure project):

public class AzureDeploymentType : IWhatDeploymentAmIUsing {
    public DeploymentType DeploymentType { get { return DeploymentType.Azure; } }
}

Now wire it up using your favorite DI tool.
