This project provides a library with a set of constraint classes that can be used to validate arbitrary values, like application settings. The constraints can be expressed in strings, so they can be stored along with the validated values. It also contains classes to consistently serialize and deserialize various data types into strings that can then be stored in formats like XML or databases.

• .NET Framework 4.6 or newer for desktop applications
• Universal Windows Platform (UWP) 10.0 (Windows 10) or newer for Windows Store Apps and Windows 10 IoT.

The project uses the following NuGet packages that are either found on NuGet.org or my own feed (see below):

• NerdyDuck.CodedExceptions

The neutral resource language for all texts is English (en-US). Currently, the only localization available is German (de-DE). If you like to add other languages, feel free to send a pull request with the translated resources!

• Use the NuGet package from my MyGet feed: https://www.myget.org/F/nerdyduck-release/api/v3/index.json. If you need to debug the library, get the debug symbols from the same feed: https://www.myget.org/F/nerdyduck-release/symbols/.
• Download the binaries from the Releases page.
• You can clone the repository and compile the libraries yourself (see the Wiki for requirements).

For examples and a complete class reference, please see the Wiki. ❗ Work in progress.
