AutoFixture cannot create a claim (with .NET Framework 4.6)

I just installed VS2015, which at the same time installed the .NET Framework 4.6, and suddenly AutoFixture 3.30.8 cannot create an object Claim. I assume that the new version of the .NET Framework version 4.6 is causing some problems in AutoFixture.

I created a test project (targeting the .NET Framework 4.5.1) containing the following code in VS2013:

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Ploeh.AutoFixture;

namespace AutoFixtureTester
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void CanCreateClaim()
        {
            var fixture = new Fixture();
            fixture.Behaviors.Add(new OmitOnRecursionBehavior());

            var claim = fixture.Create<System.Security.Claims.Claim>(); // exception here

            Assert.IsNotNull(claim);
        }
    }
}

The error is as follows:

Ploeh.AutoFixture.ObjectCreationException: AutoFixture was unable to create an instance from System.IO.Stream, most likely because it has no public constructor, is an abstract or non-public type.

Before installing VS2015, this method of creating an object is Claimused. In fact, I sent this solution to my colleague who only has VS2013 installed, and it works for him.

, F12- Claim 4.5.1 DLL. VS2015, 4.5.1 DLL? ​​AutoFixture, 4.6, ?

DotPeek System.Security.Claims.Claim . :

// Assembly location: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\mscorlib.dll

:

// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll

5 , string, ClaimsIdentity.
Mine 7 , 2 , :

public Claim(BinaryReader reader) { ... }


public Claim(BinaryReader reader, ClaimsIdentity subject) { ... }

, - AutoFixture . , Microsoft. , ?

AutoFixture, , Claim .

fixture.Customize<System.Security.Claims.Claim>(
