## Impact

Azure App Service web applications developed with the .NET software stack should use the latest available version of .NET to ensure the latest security fixes are in use.

## How to Fix

*Resource:* azurerm\_app\_service

* *Arguments:* dotnet\_framework\_version - (Optional) The version of the .net framework's CLR used in this App Service.

Possible values are v2.0 (which will use the latest version of the .net framework for the .net CLR v2 - currently .net 3.5), v4.0 (which corresponds to the latest version of the .net CLR v4 - which at the time of writing is .net 4.7.1) and v5.0. { "resource "azurerm\_app\_service" "example" { ... site\_config {

* dotnet\_framework\_version = "v4.0" ... }

## } ", }

## 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://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec-azure-80.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.
