This is a simple library to parse expressions and evaluate them. A typical use case would be to provide a macro like functionality in an application.
The easiest way is to install via Nuget. Check out Nuget for more details on how to do this.
For example, the following code sample will generate a result of 15
var runner = new Runner();
runner.Scope.SetVariable(x, 5);
var result = runner.Evaluate("x+10");
There is also support for custom functions.
