1. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, AsyncContext asyncContext, bool forceYielding)

View source

Summary: Wraps the source observable so that observer callbacks are invoked on the specified async context.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`asyncContext`	[AsyncContext](#	The async context on which observer callbacks should be invoked.
`forceYielding`	bool	When true, forces an asynchronous yield before invoking each callback, even if already on the target context.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified context.

2. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, AsyncContext asyncContext)

View source

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`asyncContext`	[AsyncContext](#	The async context on which observer callbacks should be invoked.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified context.

3. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, SynchronizationContext synchronizationContext, bool forceYielding)

View source

Summary: Wraps the source observable so that observer callbacks are invoked on the specified synchronization context.

Type parameters

`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`synchronizationContext`	SynchronizationContext	The synchronization context on which observer callbacks should be posted.
`forceYielding`	bool	When true, forces an asynchronous yield before invoking each callback.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified synchronization context.

4. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, SynchronizationContext synchronizationContext)

View source

Summary: Wraps the source observable so that observer callbacks are invoked on the specified synchronization context.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`synchronizationContext`	SynchronizationContext	The synchronization context on which observer callbacks should be posted.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified synchronization context.

5. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, TaskScheduler taskScheduler, bool forceYielding)

View source

Summary: Wraps the source observable so that observer callbacks are invoked using the specified task scheduler.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`taskScheduler`	TaskScheduler	The task scheduler on which observer callbacks should be scheduled.
`forceYielding`	bool	When true, forces an asynchronous yield before invoking each callback.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified task scheduler.

6. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, TaskScheduler taskScheduler)

View source

Summary: Wraps the source observable so that observer callbacks are invoked using the specified task scheduler.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`taskScheduler`	TaskScheduler	The task scheduler on which observer callbacks should be scheduled.

Returns: IObservableAsync -- An observable sequence whose observer callbacks execute on the specified task scheduler.

7. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, IScheduler scheduler, bool forceYielding)

View source

Summary: Configures the observable sequence to notify observers on the specified scheduler.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`scheduler`	[IScheduler](#	The scheduler on which to observe and deliver notifications to observers. Cannot be null.
`forceYielding`	bool	true to force yielding to the scheduler even if already on the target context; otherwise, false.

Returns: IObservableAsync -- An observable sequence whose notifications are delivered on the specified scheduler.

Remarks

Use this method to control the context (such as a UI thread or a specific task scheduler) on which observers receive notifications. This is useful for ensuring thread safety or updating UI elements from observable sequences.

8. Overload¶

public static IObservableAsync<T> ObserveOn<T>(this IObservableAsync<T> @this, IScheduler scheduler)

View source

Summary: Configures the observable sequence to notify observers on the specified scheduler.

Type parameters

Name	Description
`T`	The type of elements in the source sequence.

Parameters

Name	Type	Description
`this`	[IObservableAsync](#	The source observable sequence.
`scheduler`	[IScheduler](#	The scheduler on which to observe and deliver notifications to observers. Cannot be null.

Returns: IObservableAsync -- An observable sequence whose notifications are delivered on the specified scheduler.
