ASP.NET ASPX Pre-compile Errors

MS Visual Studio, by default, does not compile a project’s ASPX/ASCX pages until runtime (via IIS Just-In-Time compiler).  Unfortunately, the IIS JIT compiler is very forgiving, ignoring some syntax errors, missing custom tag libraries, un-handled events, etc.  Therefore, these types of errors may exist in ASPX pages even though the web page “works”.

This Visual Studio Post-Build Event will show these hidden ASPX errors in the Error Window when a normal REBUILD ALL is performed.
