Load DLL at runtime with shared dependency

Hello,

I'm currently attempting to make an extension loader for my application, however I'm having issues loading the assembly at runtime because a dependency is already loaded in the running assembly.

This is my current setup:

ExtensionManager.Core

ExtensionManager.Core

- this is a class library that contains the interfaces for the extension and service manager class.
-

ExtensionManager

ExtensionManager

- this is a CLI project that loads the extension DLL and registers it to a common interface (from

ExtensionManager.Core

ExtensionManager.Core

).
-

SampleExtension

SampleExtension

- this is a class library the implements the extension interfaces in

ExtensionManager.Core

ExtensionManager.Core

and is loaded at runtime.

Inside the

ExtensionManager

ExtensionManager

I attempt to load the

SampleExtension.dll

SampleExtension.dll

and get the type that implements

IServiceExtension

IServiceExtension

from

ExtensionManager.Core

ExtensionManager.Core

, however doing so throws the following exception:

Unable to load one or more of the requested types.
Method 'RegisterExtension' in type 'SampleExtension.SampleExtension' from assembly 'SampleExtension, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Unable to load one or more of the requested types.
Method 'RegisterExtension' in type 'SampleExtension.SampleExtension' from assembly 'SampleExtension, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Is there a way to tell the SampleExtension DLL to use the loaded

ExtensionManager.Core

ExtensionManager.Core

instead of loading a new one?

I'm fairly new to this sort of thing, so any help is appreciated.
