# Set up the APM .NET agent
The .NET agent can be added to an application in three different ways
<definitions>
  <definition term="Profiler runtime instrumentation">
    The agent supports auto instrumentation without any code change and without any recompilation of your projects. See [Profiler Auto instrumentation](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/apm/agents/dotnet/setup-auto-instrumentation).
  </definition>
  <definition term="NuGet packages">
    The agent ships as a set of [NuGet packages](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/apm/agents/dotnet/nuget-packages) available on [nuget.org](https://nuget.org). You can add the Agent and specific instrumentations to a .NET application by referencing one or more of these packages and following the package documentation.
  </definition>
  <definition term="Host startup hook">
    On **.NET**, the agent supports auto instrumentation without any code change and without any recompilation of your projects. See [Zero code change setup on .NET](/elastic/docs-builder/docs/3028/reference/apm/agents/dotnet/setup-dotnet-net-core#zero-code-change-setup) for more details.
