# Manual Integration

World's #1 PDF SDK Library for Web, Mobile, Server, Desktop

## Why can't I use "Any CPU" configuration for UWP?

This is because the "Any CPU" configuration cannot be used in projects that contain native code.

## Why can't I see the SDK in the Reference Manager?

If you're unable to find the `PDFNet SDK for UWP` option in your Reference Manager, it is likely that you have not properly installed the SDK. Please refer to [Setup](/uwp/get-started/integration/pdfnetcuwp.md#initial-setup) to see how you can install it.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/uwp/get-started/faq/manual-faq.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
