azure webrole Global.Application_Start is never called

Question

I created a simple ASP.NET project and then added cloud deployment descriptor using Visual Studio. Once I do that, Application_Start() method in global.asax file never gets called. In my project, I do lot of initialization such as loading web.config file, loading connection strings, initiailizing cache, etc. I can not put all of them into WebRole.OnStart() method. 

Is there any special configuration required to have Application_Start() method in Global class invoked?

Thanks,

Hi,

As far as i know, Application_start event will be invoked by Azure application (After OnStart method), please refer to this tutorial:

http://msdn.microsoft.com/en-us/wazplatformtrainingcourse_introtowindowsazurelabvs2010_topic2#_Toc313609301

void Application_Start(object sender, EventArgs e)
{
Microsoft.WindowsAzure.CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) =>  
{    
configSetter(RoleEnvironment.GetConfigurationSettingValue(configName));
});
}

Do you mean you can not set breakpoints in Application_start code block, but can not see the breakpoints works? If so, i think there's something wrong with the VS or Azure emulators, but the code in Application_Start will be invoked as usual.

Hope this helps.

Are you sure that the web role is actually starting properly ? How did your diagnose that the Application_Start is not being called ?
