[clang-format] C# attribute on auto property lead to strange formatting

[TobiasFunk]

Hey when i execute clang-format.exe --verbose --style=file -i Program.cs on this code:

using System;

namespace ConsoleApp2
{
    [AttributeUsage(AttributeTargets.All)]
    public class SimpleAttribute : Attribute
    {
    }

    internal class Program
    {
        bool AutoAllowKnownApps
        {
            get; 
            [Simple]
            set;
        }

        static void Main(string[] args)
        {
        }
    }
}

i get a really strange result code

using System;

namespace ConsoleApp2
{
    [AttributeUsage(AttributeTargets.All)]
    public class SimpleAttribute : Attribute
    {
    }

    internal class Program
    {
        bool AutoAllowKnownApps
        {
        get; [Simple]
            set;
        }

            static void Main(string[] args)
            {
            }
    }
}

i found out that it is related to the attribute when removing it everything seems to format correctly.

only for completenes i use this config but it also happens with the default config

Is there supposed be a pair of parentheses at the end of bool AutoAllowKnownApps?

You mean the curly brackets? Yes this is the common way of declare a property in c#. I found out it seems to be related to the attribute on the setter it only does this strange formatting when it is there (unluckily here it is important in our real code to have it
