HttpSysListener throws HEFException when WebApplication disposed (net10.0)

[perclausen]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When using HttpSys and targeting net10.0 WebApplication throws HEFException when disposed.

The error is only thrown when run from Visual Studio where Debugger is attached (Debug and Release).

The error is not thrown when targeting net8.0 or net9.0, so an issue introduced in net10.0.

Expected Behavior

WebApplication does not throw HEFException when disposed.

Steps To Reproduce

Please see this repository.

Exceptions (if any)

Fixed in 11.

Will the fix be back-ported to net10.0?

Is this causing you problems? It's an exception that only happens at app shutdown time.

Yes, we have a framework where we can re-configure etc. without exiting the process. So we create/dispose WebApplication objects which have been working fine up till net10.

For now we have suppressed the HEFException in or framework, but would be nice with a fix before we start using net10 :)
