MetaData Class Generator v0.1.0.0

by Frank Perez August 23, 2012

Since my first ASP.NET MVC, I've always used the Data Annotation Model Binder to perform simple validations like the following:

  • Range – validate whether the value of a property falls between a specified range of values.
  • Regular Expression – validate whether the value of a property matches a specified regular expression pattern.
  • Required – mark a property as required.
  • String Length – specify a maximum length for a string property.

The problem is that if you like to design "Database First" like me, it can take a significant amount of time to build all of the classes later. Since I'm the kind of person who hates tedious work, I created my own utility for building the classes called MetaData Class Generator. MetaData Class Generator is a console application for generating Data Annotation classes based on an existing SQL Server Database.

If you would like a copy of this application, you can download the latest version using the link below. The following is a list of important notes:

  • This application requires the Microsoft .NET Framework 4 Client Profile.
  • This application has only been tested with SQL Server 2008 R2. Other versions may work, but there could be issues mapping newer data types.
  • Be sure to read the README.TXT file for instructions on running the application.
  • I'd love to hear any feedback. What do you like, what do you not like, what kind of features would you like to see in future versions?
