If this issue only occurs in one browser, which browser is a problem?

No browser; this is a development issue

Describe the Bug

With a minimal project using yarn 4.5.1, Astro 4.16.12 and the latest official VSCode Astro extension, I'm getting an error in my src/content/config.ts file when I try to do the following import:

import { defineCollection, z } from "astro:content";

This is the error I see:

Module '"astro:content"' has no exported member 'defineCollection'.ts(2305)

I can confirm that, indeed, the defineCollection and z declarations are missing from the .astro/astro/content.d.ts typing file. (I can share the contents of that file if desired, but you should be able to reproduce with my sample.)

I've linked a minimal reproduction. To initialize the project, I just ran yarn init -2, added the relevant Astro dev dependencies, and pasted in a few filler content files. I see the same issue whether I put everything into dependencies or devDependencies in my package.json, so it does not appear to be a dev-vs-runtime dependency issue.

Note that I wasn't able to insert slashes (/) into the gist files, so I've replaced those with underscores (_).

I've also run astro sync, astro check, and astro build. All result in the same VSCode type error. I am able to successfully build and view the website.

Finally, the closest previous issue I could find to this one was https://github.com/withastro/astro/issues/5711, which seems to be complaining that the module doesn't exist at all. This is not what I'm seeing; instead, I'm seeing that not all of the module exports are getting into the declaration file.

What's the expected result?

The .astro/astro/content.d.ts should contain all relevant typings and should allow type checking of collection schemas.

I do have the same issue.

Worth to mention that the build works perfectly, it's just in Vscode.

Also here is what eslint says:

Ah anyway, I figured out I forgot to include "include": ["./src/**/*.astro"] in my tsconfig.json. Now it works like a charm, sorry for the noise.
