We needed to determine if a class was running in Azure and if so whether it was actually in the cloud or being emulated locally.

Turns out this is very simple to do, just add a reference to:

Microsoft.WindowsAzure.ServiceRuntime

And then use these two static booleans, notice the try/catch blocks, 32 bit processes throw an error here, so reporting false in the catch remedies that.

public static bool InAzureEnvironment { get { try { return RoleEnvironment.IsAvailable; } catch { return false; } } } public static bool InCloud { get { try { return InAzureEnvironment && !RoleEnvironment.IsEmulated; } catch { return false; } } }
