I tried to build a very small ASP.NET application (2 tables from SQL Server 2012) using IIS Express and Browse after generation, but ran into an error "C:\Users\<username>\Documents\IISExpress\config\applicationhost.config not found." I've tried reinstalling ASP.NET Maker and IIS Express with admin privileges. I installed the community edition of VS2013. No luck.
I then downloaded the demo (after running it on your site). It complained first about the iTextSharp DLL missing. I picked it up from the SourceForge site (sourceforge.net/projects/itextsharp/files/) which got rid of hundreds of errors. However it still complains about version errors (below) and missing the MessagingToolKit.
Errors from demo build:
Microsoft (R) Visual C# Compiler version 4.0.30319.34209
for Microsoft (R) .NET Framework 4.5
