Visual Studio has dementia

I was working on a WPF project, then I closed Visual Studio. When I opened Visual Studio again, it showed me 10 incorrect errors, which all were The name ... does not exist in the current context.. This happened by itself, I did not break anything. Trying to build with the code-behind tabs open fails but works if I close them.

✅ HTTPClient's GetAsync errors and doesn't get caught

In this code

c#
private async Task<CheckResult> TestHTTP()
{
    ...
    // above code creates httpclient as client
    try
    {
(!)     response = await client.GetAsync(expectedURL);
    }
    catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
    {
        client.Dispose();
        handler.Dispose();
        return CheckResult.TimedOut;
    }
    catch
    {
        client.Dispose();
        handler.Dispose();
        return CheckResult.TimedOut;
    }
    ...
}

c#
private async Task<CheckResult> TestHTTP()
{
    ...
    // above code creates httpclient as client
    try
    {
(!)     response = await client.GetAsync(expectedURL);
    }
    catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
    {
        client.Dispose();
        handler.Dispose();
        return CheckResult.TimedOut;
    }
    catch
    {
        client.Dispose();
        handler.Dispose();
        return CheckResult.TimedOut;
    }
    ...
}

client is a Httpclient which is supposed to timeout after a delay. To test that, I tried getting it to access a URL that doesn't work. client.GetAsync( ).Result throws a TaskCancelledException , which doesn't get caught Adding:

This function is supposed to be used in multiple threads. Maybe having the thread error out and shutdown serve as a "catch" block of sorts can work? However that is not optimal

How fix???:kekw:
