Namespace import incorrect in certain scenario

sdflysha · December 2019

I'm using LINQPad 6.6.1, first, install NuGet package SharpDX.Direct2D1 latest(4.2.0) edition.

Write following code:

PixelFormat

Click triangle and showing the correct namespace import options:

But after add SharpDX.Direct2D1 as namespace import option in Query Properties window:

Note SharpDX.WIC is missing in namespace import options, which I believe should be incorrect:

In the first instance, LINQPad generates the list of imports by searching all accessible types in the list of referenced assemblies. In the second instance, the items are generated by a Roslyn CodeFixProvider (this is normally triggered when there's an error, usually to resolve ambiguities). It seems that there's a bug in CSharpFullyQualifyCodeFixProvider which omits SharpDX.WIC. You'll see the same thing in Visual Studio if you create a project as follows:

<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">

  <PropertyGroup>
     <OutputType>WinExe</OutputType>
     <TargetFramework>netcoreapp3.1</TargetFramework>
     <UseWindowsForms>true</UseWindowsForms>
     <UseWpf>true</UseWpf>
    </PropertyGroup>

  <ItemGroup>
     <PackageReference Include="SharpDX.Direct2D1" Version="4.2.0" />
  </ItemGroup>

</Project>
