Issue Description

I am experiencing a problem with… autocomplete not working some of the time. I was able to pinpoint it to types that are not available for VSCode and it breaks autocomplete totally. In my case ExchangeServiceBase is not there because I am not connected to EWS. But I believe it’s also visible in other cases when types are just not loaded from modules.

This works

function ThisIsMyTest {
    param(
        [string] $Test,
        [string] $Hello
    )
}

ThisIsMyTest

The moment you add another parameter with type that is unknown… whole autocomplete breaks.

function ThisIsMyTest {
    param(
        [string] $Test,
        [string] $Hello,
        [Microsoft.Exchange.WebServices.Data.ExchangeServiceBase] $New
    )
}

ThisIsMyTest
