One of the new features that came with Visual Studio .NET 2008 SP1, is the real-time compiler errors (feature I read VB developers have had for a long time).

So if you type something wrong, you see it without having to compile

I've been working with it for two days, and I definitely don't like it, it distracts me to have errors appearing and disappearing all the time, it doesn't even let you finish writing the line, it shows an error when there isn't one (I just need to finish the line please!). I found myself trying to type faster to avoid seeing the "error".

I'm sure they had good intentions.

Luckily, almost anything can be turned off, you just need to find it.

If you go to Tools > Options > Text Editor > C# > Advanced, and uncheck "Show live semantic errors", it works like before, only showing hints

I will go back to the old ways with this one...
