Extended source code of the Simple Calculator MEF Application Simple calculator

MEF Example

This repository contains extended source code of the Simple Calculator MEF Application Simple calculator

This example shows the usage of the Managed Extensibility Framework (MEF)

Compilation

1. Open Program.cs
2. In the app.config, specify the path to the Extensions folder on your local computer

<add key="ExtensionsFolder" value="Extensions"/>

You can specify a relative or a full path and even reference parent paths such as ..\..\Extensions.

HINT: Every time a new part is added to the Extensions project it has to be rebuilt to make the part available to the calculator.

Test the project

1. Run the project
2. A command window appears.
3. Type addition or subtraction commands

• 1+1
• 1-2

Typing a not implemented operation symbol like 1^2 causes the message: Operation not found!
