Build a generic method with Expressions

private static TDelegate BuildHandler<TDelegate>(TServiceImpl instance, string methodName)
{
    MethodInfo method = instance.GetType().GetMethod(methodName);
    IEnumerable<ParameterExpression> parameters = method.GetParameters().Select(x => Expression.Parameter(x.ParameterType)).ToList();

    var call = Expression.Call(Expression.Constant(instance), method, parameters);
    var func = Expression.Lambda<TDelegate>(call, false, parameters).Compile();

    return func;
}
