vs2010
this is a public service announcement. the answer wasn't easy to find with simple google searches. so i'm posting it here. the problem: when using visual studio 2005 (vs2005), i added several directories to the includes, libraries, and executables paths. now we've switched to visual studio 2010 (vs2010). those paths are now part of the solution. which is a pretty good change. except... the paths added to vs2005 are now permanently inherited by all vs2010 projects. which is a bit of a problem. one solution is to run vs2005 and delete them. but that doesn't help if you've already uninstalled vs2005. fortunately, you can edit this file: c:\users\you\appdata\local\microsoft\msbuild\v4.0\microsoft.cpp.platform.user.props. it's an html-like file. you can delete the added directories using vs2010. you're welcome.
