EnvDTE is throwing an ComException when trying to get a property access modifier of a expression-bodied member

Question

I have a VS extension project.

In the project I need to traverse thru all class and find all public properties with public getters.

the code looks like

        private static IEnumerable<IntellisenseProperty> GetProperties(CodeElements props, HashSet<string> traversedTypes, HashSet<string> references = null)
        {
            return from p in props.OfType<CodeProperty>()
                   where !p.Attributes.Cast<CodeAttribute>().Any(a => "System.Runtime.Serialization.IgnoreDataMemberAttribute" == a.FullName || "Newtonsoft.Json.JsonIgnoreAttribute" == a.FullName)
                   where vsCMAccess.vsCMAccessPublic == p.Access && p.Getter != null && !p.Getter.IsShared && vsCMAccess.vsCMAccessPublic == p.Getter.Access
                   select new IntellisenseProperty
                   {
                       Name = GetName(p),
                       Type = GetType(p.Parent, p.Type, traversedTypes, references),
                       Summary = GetSummary(p),
                       JsonName = GetJsonName(p)
                   };
        }

the following input cause the issue

sing System.ComponentModel.DataAnnotations;
using Microsoft.AspNet.Identity;
using Newtonsoft.Json;
using System.Runtime.Serialization;

namespace ClaimsManager.Models.UI
{
    public class WindowsAccount
    {     
        [JsonProperty("Test")]
        public string UserName { get; set; }
        [Required]
        public string Domain { get; set; }

        public string WindowsUserID => $"{Domain}\\{UserName}"; 

        [JsonIgnore]
        public UserLoginInfo UserLogin => new UserLoginInfo("Windows", WindowsUserID);


    }
}

works great till it gets to

public string WindowsUserID => $"{Domain}\\{UserName}"; 

where it blows up on vsCMAccess.vsCMAccessPublic == p.Getter.Access with a COMException.

HResult = 0x80004005

Message "Error HRESULT E_FAIL has been returned from a call to a COM component

Source "EnvDTE"

TargetSite {EnvDTE.vsCMAccess get_Access()}

the only properties this happens on are all expression-bodied members

Is the a EnvDTE issue?

If it is an EnvDTE issue....how / where do I report it.

好吧，我放了一个错误并修复了Roslyn ....它计划在15.3版中发布
