# .NET on Windows

## Installation

Prefix uses a simple Windows installer and takes just a couple minutes to install.

Check out the [Getting Started](https://docs.stackify.com/v1/docs/prefix-getting-started) Prefix page to download and install Prefix on your workstation.

#### .NET Framework

          .NET Framework:

          

Prefix only supports v4.5.2 and later of the .NET Framework

A module used by Prefix is pre-installed into IIS during the installation. There should not be any additional configuration needed when running the app in local IIS or IIS Express.

#### .NET Core

          .NET Core:

          

Prefix only supports 2.1 and later with primary testing on LTS releases (2.1 and 3.1)

All you need to do is create a `Stackify.json` file that contains your app name as shown below.

#### Naming your Application

Create a file named `Stackify.json` and save it in the deployment folder of your application.

```
{
    "AppName": "MyApp"
}
```

This app name setting will be used to display your different apps when viewing requests and traces in Prefix.

          Important note on Stackify.json location:

          

The Stackify.json file location will differ depending on the type of application. The easiest way to ensure it's added to the correct location is to mark it in VS as "**Copy to Output Directory**" and set it as "**Copy Always**".
