# Promise

Yes it handles promises within promises.
## Async Call
```csharp

.Then(GetPersonList)
.Then, List>(GetPersonsAges)
.Then, int>(CombineAges)
.Catch(HandleNullReferenceException)
.Catch(HandleException)
.ExecuteAsync();
while (promise.IsRunning) {
Task.Delay(1);
}
var age = promise.CastTo();
```
## Sync Call
```csharp
var age = new Promise()
.Then(GetPersonList)
.Then, List>(GetPersonsAges)
.Then, int>(CombineAges)
.Catch(HandleNullReferenceException)
.Catch(HandleException)
.Execute()
.CastTo();
```
## Use Lambda functions
```csharp
var age = new Promise()
.Then(() => new Dictionary {
{"Barack Obama", 56},
{"Albert Einstein", 76}
})
.Then((Dictionary persons) => {
return persons.Sum(p => p.Value);
})
.Execute()
.CastTo();
```
