AddCascadingValue<TValue>(IServiceCollection, Func<IServiceProvider,CascadingValueSource<TValue>>)
Adds a cascading value to the serviceCollection. This is equivalent to having
a CascadingValue<TValue> at the root of the component hierarchy.
With this overload, you can supply a CascadingValueSource<TValue> which allows you to notify about updates to the value later, causing recipients to re-render. This overload should only be used if you plan to update the value dynamically.

Public Function AddCascadingValue(Of TValue) (serviceCollection As IServiceCollection, sourceFactory As Func(Of IServiceProvider, CascadingValueSource(Of TValue))) As IServiceCollectionType Parameters
- TValue
The value type.
Parameters
- serviceCollection
- IServiceCollection
The IServiceCollection.
- sourceFactory
- Func<IServiceProvider,CascadingValueSource<TValue>>
A callback that supplies a CascadingValueSource<TValue> within each service provider scope.
Returns
The IServiceCollection.
Applies to
AddCascadingValue<TValue>(IServiceCollection, Func<IServiceProvider,TValue>)
Adds a cascading value to the serviceCollection. This is equivalent to having
a fixed CascadingValue<TValue> at the root of the component hierarchy.
