Condition false, but code inside the if statement executed

Question

I have the following method:

public bool ConnectAsync()
{
    if (IsConnected)
        throw new InvalidOperationException(\"Socket is already connected\");

This answer explained the problem I was having: https://stackoverflow.com/a/27552124/1830461

Something of this format compiled to 64-bit can cause the debugger to step into the if statement:

        if (falseCondition) 
            throw new Exception(); 
        try { }  catch { }

It's a bug in Visual Studio. The code isn't actually executed. The solution is to just ignore it and continue stepping through the code. Putting a lock statement on it fixes it, because it is no longer in that format.
