# Keeping Your Agent Updated

### Problem <a href="#problem" id="problem"></a>

When configuring the SeaLights agent for DotNet, it isn't easy to manage the agent files in the correct version - especially in standalone environments (containers, backend servers, etc)

### Solution <a href="#solution" id="solution"></a>

The following PowerShell script checks for the recommended agent and latest version, and in case it does not exist locally - downloads & unzips it in the given directory.

#### Downloading the Recommended Agent set in settings <a href="#downloading-the-recommended-agent-set-in-settings" id="downloading-the-recommended-agent-set-in-settings"></a>

{% code overflow="wrap" lineNumbers="true" %}

```powershell

$previousProgressPref=$global:ProgressPreference
$global:ProgressPreference = "SilentlyContinue" #Disable Progress bar to speed up download and expand

$sldomain="mycompany.sealights.co" #Update with your customer domain
$slToken="$(Get-Content sltoken.txt)" #Prefer a credential Environment variable for the token

Write-Output "Retrieve version from Sealights settings..."

## 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/troubleshooting-faq/.net-.netcore/keeping-your-agent-updated.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.
