The `DynamicLinqType` attribute can not be added to interfaces.

I can remove the restriction for only using it on classes and structs.

Great! Thank you!

I've update the attribute and created this this test:

[DynamicLinqType]
    public interface ICustomInterfaceWithMethodWithDynamicLinqTypeAttribute
    {
        int GetAge(int x);
    }

    public class CustomClassImplementingInterface : ICustomInterfaceWithMethodWithDynamicLinqTypeAttribute
    {
        public int GetAge(int x) => x;
    }

        // Arrange
        var context = new CustomClassImplementingInterface();
        var expression = $"{nameof(ICustomInterfaceWithMethodWithDynamicLinqTypeAttribute.GetAge)}(10)";

        // Act
        var lambdaExpression = DynamicExpressionParser.ParseLambda(typeof(ICustomInterfaceWithMethodWithDynamicLinqTypeAttribute), null, expression);
        var del = lambdaExpression.Compile();
        var result = (int?)del.DynamicInvoke(context);

        // Assert
        result.Should().Be(10);

This is what you need?
