Enables fundamental Windows Runtime functionality, including managing asynchronous operations, accessing property stores, and working with images and Uniform Resource Identifiers (URIs).
Members
The Windows.Foundation namespace has these types of members:
Classes
The Windows.Foundation namespace has these classes.
| Class | Description |
|---|---|
| PropertyValue | Represents a value in a property store. |
| Uri | Parses Uniform Resource Identifier (URI). |
| WwwFormUrlDecoder | Parses a URL query string. |
Delegates
The Windows.Foundation namespace has these delegates.
| Delegate | Description |
|---|---|
| AsyncActionCompletedHandler | Represents a method that handles the completed event of an asynchronous action. |
| AsyncActionProgressHandler(TProgress) | Represents a method that handles progress update events of an asynchronous action that provides progress updates. |
| AsyncActionWithProgressCompletedHandler(TProgress) | Represents a method that handles the completed event of an asynchronous action that provides progress updates. |
| AsyncOperationCompletedHandler(TResult) | Represents a method that handles the completed event of an asynchronous operation. |
| AsyncOperationProgressHandler(TResult, TProgress) | Represents a method that handles progress update events of an asynchronous operation that provides progress updates. |
| AsyncOperationWithProgressCompletedHandler(TResult, TProgress) | Represents a method that handles the completed event of an asynchronous operation that provides progress updates. |
| EventHandler(T) | Represents a method that handles general events. |
| TypedEventHandler(TSender, TResult) | Represents a method that handles general events. |
Enumerations
The Windows.Foundation namespace has these enumerations.
| Enumeration | Description |
|---|---|
| AsyncStatus | Specifies the status of an asynchronous operation. |
| PropertyType | Specifies property value types. |
Interfaces
The Windows.Foundation namespace implements these interfaces.
| Interface | Description |
|---|---|
| IAsyncAction | Represents an asynchronous action. |
| IAsyncActionWithProgress(TProgress) | Represents an asynchronous action that includes progress updates. |
| IAsyncInfo | Supports asynchronous actions and operations. |
| IAsyncOperation(TResult) | Represents an asynchronous operation. |
| IAsyncOperationWithProgress(TResult, TProgress) | Represents an asynchronous operation that includes progress updates. |
| IClosable | Defines a method to release allocated resources. |
| IGetActivationFactory | Defines the implementation for a type that retrieves activation factories. |
| IPropertyValue | Represents a value in a property store. |
| IReference(T) | Enables arbitrary enumerations, structures, and delegate types to be used as a property values. |
| IReferenceArray(T) | Enables arbitrary enumerations, structures, and delegate types to be used as an array of property values. |
| IWwwFormUrlDecoderEntry | Represents a name-value pair in a URL query string. |
Structures
The Windows.Foundation namespace has these structures.
| Structure | Description |
|---|---|
| DateTime | Represents an instant in time, typically expressed as a date and time of day. |
| EventRegistrationToken | Represents a reference to a delegate that receives change notifications. |
| HResult | Represents an error or warning. |
| Point | Represents an ordered pair of floating-point x- and y-coordinates that defines a point in a two-dimensional plane. |
| Rect | Contains a set of four floating-point numbers that represent the location and size of a rectangle. |
| Size | Represents an ordered pair of floating-point numbers that specify a height and width. |
| TimeSpan | Represents a time interval. |
