Having an ol’ sk00l application that uses classic dotnet can be a challenge sometimes. Yesterday I ran into an issue that required me to debug the Application_Start() method of Global.asax.
The Application_Start did a bunch of stuff - herein bundle the client assets (CSS and JS files). But the content did not render. Since this runs on application start - hence before the process is running it is a bit of a pickle to attache to the IIS process for debugging.
To the rescue System.Diagnostics.Debugger!!
Setting this line at the top (or whereever I want to break into debugging) helped solve the problem.
protected void Application_Start()
{
System.Diagnostics.Debugger.Launch();
// YOUR START CODE
}
Happy debugging :)
