As usual you can install or update Geta Tags using NuGet.
Install-Package Geta.Tags
Then add UIHint("Tags") attribute to the properties where you want to use tags.
[UIHint("Tags")] public virtual string Tags { get; set; }
In edit mode this property uses tag-it jQuery UI plugin for selecting tags and also provide auto suggestion of previously stored tags. New tags are stored when page is published.
Latest version automatically registers required MVC routes. No need for manual or default MVC route definitions in your EPiServer project.
In addition we've downgraded the package to work with both .NET 4 and .NET 4.5 applications.
