New Post: IIS websites

I'm using the latest wixsharp package, WebSite constructor does not take three string arguments. When I remove the third argument I get this error:

...\bin\Release\WixSharpSetup.exe" "/MSBUILD:SetupWixSharpCustomUI"" exited with code -532459699. SetupWixSharpCustomUI

I haven't found a working IISVirtualDir example yet.
