Unity3d: How to use dll from Javascript?

Question

I have written a dll in C# to perform several tasks for my game. I can successfully use that dll when I use it from a C# script in Unity. But when I use the dll from Javascript, it gives this error:

Namespace 'MyLibrary' not found, maybe you forgot to add an assembly reference?

I have placed MyLibrary.dll under Assets folder. This is how I access it from C#:

using MyLibrary;

This is how I access it from Javascript:

import MyLibrary;

So, I can use it from C#, but how can I also use it from Javascript?

Kindly tell me how? Because in C#, I can use it without adding a reference. — Salman Younas

You're thinking of "Unityscript". It is no longer available in Unity. You must change to c#. — Fattie

NATIVE PLUGIN:

C#:

[DllImport ("PluginName")]
private static extern float functionName ();

JavaScript:

@DllImport (DLLName)
static private function functionName () : float {};

MANAGED PLUGIN:

C#:

using MyLibrary;

JavaScript:

Go to your project directory, look for YourProjectName.CSharp.csproj

Find it, open it and add <Reference Include="MyLibrary"> into it then save it. Restart Unity and Visual Studio.

Put the DLL into the Assets folder.
