These block helpers use System.Linq.Dynamic.Core.

• DynamicLinq.Expression v1
• Linq / DynamicLinq.Expression v2
• All
• . . .
• DynamicLinq.FirstOrDefault
• ...
• DynamicLinq.Where

A breaking change is introduced which is related to System.Linq.Dynamic.Core DynamicLinq (CVE).

The NuGet Handlebars.Net.Helpers.DynamicLinq will not be loaded automatically anymore. You need to allow this via the configuration. In addition, an extra configuration setting is added to allow the use of ToString and Equals on an object.

Example:

var handlebarsContext = HandlebarsDotNet.Handlebars.Create();
HandlebarsHelpers.Register(handlebarsContext, o =>
{
    o.DynamicLinqHelperOptions = new HandlebarsDynamicLinqHelperOptions
    {
        Allow = true,
        AllowEqualsAndToStringMethodsOnObject = true
    };
});
