What is the best way to determine if my web application code is running in a Azure web role (or emulator)?
I need to configure a dependency injection container and do not want to take a dependency on any Azure specific assemblies unless I'm running in Azure.
Both answers to this question require referencing Azure specific assemblies which I'd like to prevent for my on-premise scenario.
Update: I'm really looking for something in the runtime environment that I can query from my web application code.
Best How To :
You could do this with via a web.config / app.config / ServiceConfiguration.cscfg setting that you only set in the specific environments that you want.
Add a parameter, for example:
<Setting name="PaaS" value="true" />
Then, at application startup, get the value:
public bool IsPaaS
{
get
{
var res = false;
var val = CloudConfigurationManager.GetSetting("PaaS") ?? "false";
Boolean.TryParse(val, out res);
return res;
}
}
CloudConfigurationManager.GetSetting will fall back if there is no cscfg setting present, and check the web.config and/or app.config.
Set this in the WebRole, but not in the web.config when running under local IIS to get the behavior you are looking for.
