What is Cadru?

The following packages have been retired. They are still available on NuGet, but shouldn't be used.

  • Cadru.TransientFaultHandling - This package has been retired and should be replaced with *Cadru.Polly.
  • Cadru.Net - This package is renamed to *Cadru.Net.Http
  • Cadru.Core.Windows - This package is retired, and features migrated to Cadru.Environment, Cadru.IO, and Cadru.Net.NetworkInformation as appropriate.
  • Cadru.IO - This package will eventually be retired and replaced with Cadru.Extensions.FileProviders.

What's next for Cadru?

The most significant update planned will be support for .NET 5 when it releases in November. Until then, there are a handful of known tasks still left. See the Cadru 5.0 milestone for more details. There are only a few issues in there right now, but I will be adding more over time.

Why another library?

Although Cadru was released as an open source framework in July 2013, some of the APIs it contains were created as early as 2003 and have been used in a variety of real world solutions. These are things that I kept having to rewrite in the apps I was building. Rather than continuing to rewrite them, I decided to encapsulate them in a library and make it broadly available. Although Cadru grew from app development, I have rewritten everything with a focus on being an API rather than a jumbled collection of utilities. That means everything is (hopefully) well documented, cleanly written, and easy to use.

Documentation

There are also a lot of unit tests that show how to use the APIs which can be a good starting place as well. (My goal is to as be as close to 100% code coverage as possible. Obviously, that will always be a work in progress.)

The long-term goal is to put the documentation online somewhere (probably as wiki pages hosted in the repository), but I don't have a time frame for when that will be complete. Until then, the source code is fully commented using XML documentation comments to provide IntelliSense support in Visual Studio.

Bugs and feature requests

Do you have a bug or a feature request? Please use the issue tracker and search for existing and closed issues. If your problem or request isn't addressed yet, go ahead and open a new issue.

Contributing

You can also get involved and fork the repository to submit your own pull requests. (More detailed contributor guidelines will be available soon.)

Versioning

For transparency and to maintain backward compatibility (as much as possible), Cadru uses the Semantic Versioning guidelines.
