Profiling ASP.NET applications running on IIS Express - ANTS Memory Profiler

IIS Express is a free version of IIS, commonly used in development environments. Like the ASP.NET built-in development server, Cassini, IIS Express can run on development machines without requiring the installation of a full web server, and does not require an administrator account to run. This makes it convenient for testing debug builds of web applications.

You can profile sites running on IIS Express by following the instructions below.

Setting up the Memory Profiler

To profile ASP.NET applications running on IIS Express, on the ANTS Memory Profiler Settings dialog box, perform the following steps:

Under Choose application type to profile, click ASP.NET web application (IIS Express).
Set the Web application path or config file for the web application that you want to profile.
You can specify the path directly to the web application, or to the site's ApplicationHost.config file. If you select the ApplicationHost.config file, a list of available applications configured in that file is displayed: select the application you want to profile.

You should normally leave Profile child processes and Monitor disposal of objects selected, although monitoring the disposal of objects may affect the performance of your application.
If required, change the performance counters to record; see Setting up Charting Options.
Click .
IIS Express starts and the web application is shown in Internet Explorer. Note that, although you can interact with the application using any web browser, closing the Internet Explorer instance opened by ANTS Memory Profiler will end your profiling session.
Check whether there are any memory problems.
