Avoiding first chance exception messages when the exception is safely handled


The following bit of code catches the EOS Exception

using (var reader = new BinaryReader(httpRequestBodyStream)) {

    try {
        while (true) {
    } catch (EndOfStreamException) { }

So why do I still receive first-chance exceptions in my console?

A first chance exception of type 'System.IO.EndOfStreamException' occurred in mscorlib.dll

Is there a way to hide these first chance exception messages?

Accepted Answer

The point of "first-chance" exceptions is that you're seeing them pre-handler so that you can stop on them during debugging at the point of throwing. A "second-chance" exception is one that has no appropriate handler. Sometimes you want to catch "first-chance" exceptions because it's important to see what's happening when it's being thrown, even if someone is catching it.

There's nothing to be concerned with. This is normal behavior.

To avoid seeing the messages, right-click on the output window and uncheck "Exception Messages".

However, seeing them happen might be nice, if you're interested in knowing when exceptions are thrown without setting breakpoints and reconfiguring the debugger.
