Visual Studio shipped the final release of service pack 1 today.
Among many of the bug-fixes and performance enhancements, the service pack fixed a pesky C++ bug which caused the linker to crash when compiling HouseBot.
A few words of warning about the service pack - it is huge - 431Mb compressed! It installed on my workstation in about an hour. However, it failed to install on my laptop after about an hour due to insufficient memory.
