Summary

This page provides an overview of the Enterprise Library Validation Application Block. An application block is reusable and extensible source code-based guidance that simplifies development of common validation functionality in .NET Framework applications. The Enterprise Library Validation Application Block provides a library of classes, called validators, that supplies the code for validating .NET Framework data types. For example, one validator checks for null strings and another validator checks that a number falls within a specified range.
