And more...

• date and time display helpers (based on timezone, standard formats, tag...)
• PageInfo is the one object to set your page title, description, meta tags, opengraph values...

And more...

All assemblies are signed. The real key is not in source control; I keep it to ensure my builds are only made by myself (yes, I know that not 100% true).

The latest build can be found here: https://www.nuget.org/packages?q=Tags%3A%22srktoolkit%22

Want unsigned assemblies? Get the code, remove the option and build.
