Simple demonstration of interaction with windows calculator

This app is just for short demonstration of Automation abilities in .NET. Not all code is covered with tests but it's a way to future improvements.

In code you can find several implementations of the interfaces - it's just for example.

For example you can use:

private IExpressionEvaluator _expressionEvaluator = new SilentExpressionEvaluator();

or

private readonly IExpressionEvaluator _expressionEvaluator = new ScreenCalcExpressionEvaluator();

• Before using of calculator interaction please run it and make sure if it is in the basic view.
• 0 should be on the calculator screen.
• In the App.config, set "CalcName" to be equal to a caption on the your calculator's window

It is possible to use any evaluation engine, any parsing expressions engine

• DI to be added.
• More tests
• Automatically choose calculator type
• Replace regex parsing with a proper grammar parsing (see BNF)
• Maybe graphic recognition feature for handling calc

It was an option to use ETL-pattern but it looks too complicated here

v. 1.0.1.0 - Added support of a Windows 10 calculator. See ScreenMetroCalcExpressionEvaluator
