Exception Hunter has been discontinued. With the release of .NET 4.0 and WPF, the number of exceptions that the CLR can throw was greatly increased, to the point of being overwhelming. The exclusions list can no longer cover all the unlikely exceptions that the CLR may throw. This means that, although Exception Hunter will provide accurate results, these results will include a long list of potential exceptions, most of which are nothing to worry about. In essence, the tool has become a lot less usable and makes your job harder than it should be. This goes against red Gate's "ingeniously simple" ethos, so they have decided to stop selling new licenses for the product.
