I\'ve a problem with loading Web Application project in VS2013. This project depends on IIS Express, but I wouldn\'t install IIS Express because I already installed IIS.
If nothing works, try removing following two lines from .csproj file. (always worked for me)
.csproj
{3AA499DF-4A65-43B7-8965-D08A4C811834} {349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}
