Class NoMessagePumpSyncContext

Namespace

Microsoft.VisualStudio.Threading

Assembly

Microsoft.VisualStudio.Threading.dll

A SynchronizationContext whose synchronously blocking Wait method does not allow any reentrancy via the message pump.

Constructors

NoMessagePumpSyncContext()

Initializes a new instance of the NoMessagePumpSyncContext class.

public NoMessagePumpSyncContext()

Remarks

When using this constructor, Post(SendOrPostCallback, object?) uses the default SynchronizationContext behavior and schedules work on the thread pool, while Send(SendOrPostCallback, object?) uses the default SynchronizationContext behavior and invokes the callback synchronously on the calling thread.

NoMessagePumpSyncContext(SynchronizationContext)

Initializes a new instance of the NoMessagePumpSyncContext class.

public NoMessagePumpSyncContext(SynchronizationContext underlyingSyncContext)

Parameters

underlyingSyncContext SynchronizationContext

The SynchronizationContext that should handle calls to Post(SendOrPostCallback, object?) and Send(SendOrPostCallback, object?).

Properties

Default

Gets a shared instance of this class.

public static SynchronizationContext Default { get; }

Property Value

SynchronizationContext

Methods

Post(SendOrPostCallback, object?)

public override void Post(SendOrPostCallback d, object? state)

Parameters

d SendOrPostCallback

state object

Send(SendOrPostCallback, object?)

public override void Send(SendOrPostCallback d, object? state)

Parameters

d SendOrPostCallback

state object

Wait(IntPtr[], bool, int)

Synchronously blocks without a message pump.

public override int Wait(IntPtr[] waitHandles, bool waitAll, int millisecondsTimeout)

Parameters

waitHandles IntPtr[]

An array of type IntPtr that contains the native operating system handles.

waitAll bool

true to wait for all handles; false to wait for any handle.

millisecondsTimeout int

The number of milliseconds to wait, or Infinite (-1) to wait indefinitely.

Returns

int

The array index of the object that satisfied the wait.
