Sorry. I was off target with my first attempt. Here is something I've slapped together referencing a post on StackOverflow. This is untested, but it should get you moving in the right direction.

using System;
using System.Text.RegularExpressions;

namespace Dado.ComponentModel.DataMutations
{
	[AttributeUsage(AttributeTargets.Property)]
	public class ToSentenceCaseAttribute : MutationAttribute
	{
		public override int Priority { get; set; } = 40;
		
		protected override object MutateValue(object value, IMutationContext context)
		{
			if (value != null && value is string valueAsString) {
				return new Regex(@"(?<=(^|[.;:])\s*)[a-z]", RegexOptions.Compiled)
					.Replace(valueAsString, (match) => match.Value.ToUpper());
			}

			return value;
		}
	}
}
