Hi there,

I'm trying to do some native windows rust programming. I'm using native-windows-gui and native-windows-derive to do it, but if I try to mix that with tokio, I get the following:

No entry point found error for GetWindowSubclass. On console, I get:

error: process didn't exit successfully: `C:\source\myprojectanem\target\debug\myprojectname.exe` (exit code: 0xc0000139, STATUS_ENTRYPOINT_NOT_FOUND)

If I change

#[tokio::main]
async fn main() {

to:

fn main() {

The problem goes away, but obviously I can't use tokio then.

Any clue what the problem is and how to fix it?

    wouldn't it be better to use #[cfg(target_os = "windows")] instead of checking an env variable?
