How to reference assemblies using Visual Studio Code?

Question

I would like to reference the System.Drawing.dll in a console app I am writing using Visual Studio Code on OSX. ie I want to use these using statements

using System.Drawing;
using System.Drawing.Imaging;

to avoid this build error

Program.cs(56,20): error CS0246: The type or namespace name `Bitmap' could not be found. Are you missing an assembly reference?

I can't find a tutorial on this, I don't even know if the dll is available in .net core or mono or whatever visual-studio-code uses.

Answer 1

In your .csproj file, add your dependency as a PackageReference in an ItemGroup , then run dotnet restore or nuget restore . Example:

<ItemGroup>
  <Reference Include="System" />
  <Reference Include="System.Xml" />
  <Reference Include="System.Core" />
  <Reference Include="Xamarin.iOS" />
  <PackageReference Include="Realm" Version="2.1.0" />
  <PackageReference Include="xunit">
    <Version>2.3.1</Version>
  </PackageReference>
</ItemGroup>

Take a look at this article for a full explanation.
