This topic describes a new installation for the .NET Agent.

If you want to install the .NET Agent from the command line, see Unattended Installation for .NET.
For .NET Agent upgrades, see Upgrade the .NET Agent.

Install the .NET Agent once on each system that hosts managed .NET applications: IIS applications, Windows services, or standalone applications. At start up, the agent initializes an individual instance of itself for each application running in the CLR.

Installing the .NET Agent

Installing the .NET Agent (agent), involves the following process:

Install the the agent according to the installation procedure.
Configure the agent.
AppDynamics provides a configuration utility to configure IIS applications. Monitoring Windows services and standalone applications requires additional manual configuration.
Restart instrumented applications.
The configuration utility gives you the option to restart IIS or not.

- If you don't restart IIS, monitoring doesn't begin until the next time IIS restarts.
- You must restart Windows services and standalone applications manually.
