# Component Context

Any derived `RxComponent` class can access a Context property that returns a `RxContext` object shared with any other component in the visual tree.

An `RxContext` is essentially a `Dictionary<string, object>` that you can use to store or retrive global variables: for example a service container object or current logged user.

`RxApplication` can be created also passing a value in the Context of the root component; for example in the following code we are passing a service provider object to the root component:

```csharp
ServiceProvider = RegisterServices();
_app = RxApplication.Create<ShellComponent>(this)
    .WithContext("ServiceProvider", ServiceProvider)
```

Any component under root component can access the context:

```csharp
var serviceProvider = (IServiceProvider)Context["ServiceProvider"];
```
