What is a No Managed Code Application Pool?
A No Managed Code Application Pool, as the name suggests, is an application pool in which no managed code is allowed to run. Managed code refers to code that is executed within the Microsoft .NET framework, which provides developers with a managed execution environment and various services such as memory management and exception handling.
Key Takeaways
- A No Managed Code Application Pool does not allow managed code to run.
- It is ideal for hosting non-.NET web applications.
- Running applications in a No Managed Code Application Pool can improve performance.
Did you know that No Managed Code Application Pools are also known as “Classic” application pools in IIS?
When to use a No Managed Code Application Pool?
A No Managed Code Application Pool is typically used when hosting web applications that do not require the .NET framework to run. This may include applications built using other programming languages such as PHP, Python, or Java. Running these applications in a No Managed Code Application Pool can provide performance benefits by avoiding the overhead of running the .NET framework for non-.NET applications.
Additionally, a No Managed Code Application Pool can be useful when you want to isolate non-.NET applications from any potential issues that may arise in the .NET framework or other .NET-based applications running on the same server. Isolating different types of applications in separate application pools can help prevent compatibility issues and ensure the stability of each application.
Advantages of using a No Managed Code Application Pool
