<ExtensionAttribute> _
Public Shared Function ObserveOn(Of TSource) ( _
    source As IObservable(Of TSource), _
    context As SynchronizationContext _
) As IObservable(Of TSource)
'Usage
Dim source As IObservable(Of TSource)
Dim context As SynchronizationContext
Dim returnValue As IObservable(Of TSource)

)
static member ObserveOn : 
        source:IObservable<'TSource> * 
        context:SynchronizationContext -> IObservable<'TSource> 
JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.

Parameters

Return Value

Type: System.IObservable<TSource>
The source sequence whose observations happen on the specified synchronization context.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
