# .NET/C# Agent

Use the .NET Agent to collect build, coverage, and test data from C# applications.

It supports:

* Windows, Linux, and Alpine environments
* Build scanning with symbol-based mapping
* Test capture and runtime coverage flows

{% hint style="warning" %}
The .NET Agent supports **C# applications only**. F# and VB applications are not supported.
{% endhint %}

{% hint style="info" %}
Visible documentation now uses **.NET Agent**. Some download endpoints still use `dotnetcore` in the URL. Keep those endpoint paths unchanged.
{% endhint %}

### Start here

Follow these pages in order:

1. [Download the agent](/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent/downloading-the-.net-core-agent.md)
2. [Scan the build binaries](/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent/scanning-the-build-binaries.md)
3. [Capture runtime coverage](/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent/capturing-coverage-from-the-application/capturing-coverage-from-the-app-process.md)
4. [Run tests](/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent/running-tests.md)
   {% endstep %}

{% step %}

### Choose the coverage path

Use the flow that matches your setup.

* Use [Capturing coverage from the app process](/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent/capturing-coverage-from-the-application/capturing-coverage-from-the-app-process.md) when you can wrap the app or test runner command.
* Use the background listener flow when the startup command must stay unchanged.
  {% endstep %}
  {% endstepper %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sealights.io/knowledgebase/setup-and-configuration/sealights-agents-and-plugins/.net-core-agent.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
