[BADF00D]

Description

When using CodeFix "Dispose in Dispose Method" on a Field/Property that is in a class without IDisposable implementation but another base class, IDisposable Interface is added as first BaseType in BaseList. This yields an Compilation error.

Source Code

This:

using System;
using System.IO;

namespace SelectManyTest {
    internal class Issue95 : Object {
        public IDisposable MemoryStream { get; }

        public Issue95()
        {
            MemoryStream = new MemoryStream();
        }
    }
}

Becomes:

using System;
using System.IO;

namespace SelectManyTest {
    internal class Issue95 : IDisposable, Object {
        public IDisposable MemoryStream { get; }

        public Issue95()
        {
            MemoryStream = new MemoryStream();
        }

        public void Dispose() {
            MemoryStream?.Dispose();
        }
    }
}

But should become:

using System;
using System.IO;

namespace SelectManyTest {
    internal class Issue95 : Object, IDisposable {
        public IDisposable MemoryStream { get; }

        public Issue95()
        {
            MemoryStream = new MemoryStream();
        }

        public void Dispose() {
            MemoryStream?.Dispose();
        }
    }
}

Will probably be part of release 1.1.3
