        {
            return

        {{fieldSyntax}}
        /// <inheritdoc cref="{{fieldName}}"/>
        {{propertyAttributes}}
        {{propertyInfo.TargetInfo.TargetVisibility}}{{propertyInfo.Inheritance}} {{propertyInfo.UseRequired}}{{partialModifier}}{{propertyInfo.TypeNameWithNullabilityAnnotations}} {{propertyInfo.PropertyName}}
        { 
            get => {{propertyInfo.FieldName}};
            [global::System.Diagnostics.CodeAnalysis.MemberNotNull("{{fieldName}}")]
            {{propertyInfo.AccessModifier}} => this.RaiseAndSetIfChanged(ref {{fieldName}}, value);
        }
""";
