(Generated summary) ConnectAsync can throw synchronously (e.g. WININET_E_INVALID_CA / 0x80072EE1 on certificate validation failure) before returning an IAsyncAction. Move the call inside the existing try/catch block so such exceptions are routed through Fail() instead of propagating unhandled. Add ConnectAsyncThrowsSynchronously unit test to cover this path.

Description
Handle synchronous exceptions from
IMessageWebSocket::ConnectAsync.Type of Change
Why
Unexpected WebSocket connection errors may cause a synchronous exception to be thrown, which is not converted into an HRESULT by the
lessthrow_awiat_adapterbecause it only handles asynchronous exceptions originated during the coroutine suspend/resume cycle.What
Add the
ConnectAsynccall to an existingtry-catchhandling block in the same code block.Testing
