Hi, I'm instrumenting an app manually because it uses the windows self-host to run as a local service, when creating a new transaction how can I get the content of the body and set it manually in the new transaction?

The objective is to know the information that the client passes to an api when there is an object reference error.

The body is stored in the `transaction.Context.Request` property - in general things that the agent stores on specific events is on the `Context`.

So you'd do something like this:

```auto
transaction.Context.Request = new Request(method, new Url{Full = url}){Body = "[SET BODY HERE]"};

```

Remaining question is, how do you get the URL values, the method and the body itself. I don't know the specifics of your app, but don't you have access to the static `HttpContext` property? These things are usually stored there. So, ideally you'd be able to read the values via the `HttpContext` and just store those on `Transaction.Context`.
