title: Installation
description: Install AutoFixture 5.0.0-rc.1 from NuGet for .NET 8 and later test projects.
---

Add AutoFixture to your test project from NuGet. Pin the version so everyone on the team uses the same release.

## Prerequisites

- [.NET 8 SDK](https://dotnet.microsoft.com/download) or later
- An existing test project (xUnit.net 3, NUnit 4, or plain test class library)

## Install AutoFixture

Add the core package to your test project:

```xml
<PackageReference Include="AutoFixture" Version="5.0.0-rc.1" />
```

Or with the .NET CLI:

```bash
dotnet add package AutoFixture --version 5.0.0-rc.1
```

## Verify installation

After restore, confirm you can create a fixture and generate a value:

```csharp
var fixture = new Fixture();
var value = fixture.Create<int>();
Assert.NotEqual(default, value);
```

If this passes, AutoFixture is ready to use in your tests.
