Jetbrains.Annotations namespace is duplicated after applying changes

[imanushin]

Steps to reproduce:

1. Open file with Jetbrains.Annotations namespace declared
2. Apply code fix for the one of the function arguments
3. Check the namespaces

Before:

using JetBrains.Annotations;
using System.ComponentModel;
using System.Runtime.CompilerServices;
using CheckContracts;

After:

using JetBrains.Annotations;
using System.ComponentModel;
using System.Runtime.CompilerServices;
using CheckContracts;
using JetBrains.Annotations; //duplicated !!!

Thanks for reporting this. However I cannot reproduce with the steps above. It would help if you could attach a sample project.

1. Download project
2. Open file in MSVS
3. Go to line 18, to argument "PortableSize maxSize"
4. Press Ctrl-'.'
5. Select "Add NotNull"
6. Apply
7. Check the namespaces

Before:

using System;
using System.Collections.Generic;
using System.Collections.Immutable;
using System.Linq;
using CheckContracts;
using JetBrains.Annotations;

Expected after:

using System;
using System.Collections.Generic;
using System.Collections.Immutable;
using System.Linq;
using CheckContracts;
using JetBrains.Annotations;

Actual after:

using JetBrains.Annotations; // <--- this line was added after the code fix
using System;
using System.Collections.Generic;
using System.Collections.Immutable;
using System.Linq;
using CheckContracts;
using JetBrains.Annotations;

@imanushin The related fix in roslyn has been merged. This should light up in the next VS release.
