### The return type

​

When you use the `Execute` method, you have 2 choices that will affect the return type. You can specify:

​

1. **A TResult**: `Eval.Execute<TResult>(code)`

2. **Nothing**: `Eval.Execute(code)`

​

1 - If you use the generic `Execute` method and specify a `TResult` type (`Eval.Execute<TResult>(code)`), the method will return a `TResult`

​

2 - If you don't specify a return type (`Eval.Execute(code)`), the method will return an `object`. Under the hood, the `Eval.Execute<object>` method is called.
