C# Eval Expression MD5 Exception

Problem

You execute a method from the Eval Expression.NET library, and the following error is thrown:

This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

Solution

Cause

The default algorithm to validate the license key & name is not supported with FIPS enabled.

Fix

Ask for a compatible key

Contact us and we will send you a new key supporting FIPS: info@zzzprojects.com

Why don't we generate a key compatible with FIPS by default? Because it will not be supported for a client machine with Windows XP or below.
