These labs provide a group of debugging scenarios focused on helping you get some hands on experience in debugging the most common type of IIS issues. For example, hang/performance, crash and memory issues.
Installation
These labs are focused IIS 8.5, but can be run on the following versions of IIS
| IIS Version | Operating System |
| IIS 10 | Windows Server 2019 |
| IIS 10 | Windows Server 2016 |
| IIS 8.5 | Windows Server 2012 R2 |
| IIS 7.5 | Windows Server 2008 R2 |
Test project – CSharpGuitarBugs
The labs utilize an ASP.NET MVC web application hosted on GitHub here. This ASP.NET MVC web application is based on version 5 using Visual Studio 2015, therefore in Lab 2, you need to install the appropriate supporting MVC libraries and .NET Framework.
