Windows Workflow Foundation Activity Pack for Windows Azure

Last week Microsoft released the Workflow Foundation (WF) Activity Pack for Windows Azure. The package is also available via NuGet(Package name=WFAzureActivityPack) and through their CodePlex page.

“The WF Activity Pack for Windows Azure CTP 1 is the first community technology preview (CTP) release of Windows Azure activities implementation based on Windows Workflow Foundation in .NET Framework 4.0 (WF4) and Windows Azure SDK. The implementation contains a set of activities based on Windows Azure Storage Service and Windows Azure AppFabric Caching Service, which enables developers to easily access these Azure services within a workflow application.”

The current release includes the following Workflow activities:

For Windows Azure Storage Service - Blob

  • PutBlob creates a new block blob, or replace an existing block blob.
  • GetBlob downloads the binary content of a blob.
  • DeleteBlob deletes a blob if it exists.
  • CopyBlob copies a blob to a destination within the storage account.
  • ListBlobs enumerates the list of blobs under the specified container or a hierarchical blob folder.

For Windows Azure Storage Service - Table

  • InsertEntity<T> inserts a new entity into the specified table.
  • QueryEntities<T> queries entities in a table according to the specified query options.
  • UpdateEntity<T> updates an existing entity in a table.
  • DeleteEntity<T> deletes an existing entity in a table using the specified entity object.
  • DeleteEntity deletes an existing entity in a table using partition and row keys.
