In some scenarios, the ExpressionEditor graphical user interface is not required, but its parsing logic for a given expression is. With the Telerik UI for WPF ExpressionParser you can easily parse expressions through several methods.
You can use the Parse method to try to directly parse the expression and return a LambdaExpression if successfully parsed.
The two overloads of the ParseAsync method operate in the same manner as the Parse method, with the difference being that they are performed asynchronously. In the second overload, aside from the expression to be parsed, you can pass a cancellation token that will be assigned to the new task.
