Workspaces

2.0

Libraries

ProtoInterface

1.0.0

ProtoInterface.dll has been removed from Dynamo project and some of the common interfaces and Attributes defined inside ProtoInterface.dll are now moved to DynamoServices.dll. If your library/package was referencing ProtoInterface.dll then it is recommended to update the reference and re-compile your projects with DynamoServices.
- Attributes defined in Autodesk.DesignScript.Runtime namespace such as [SupressImportIntoVM], [IsVisibleInDynamoLibrary(bool)] and [MultiReturn(params string[])] are now part of DynamoServices.dll
- Graphics visualization related interface and class defined in Autodesk.DesignScript.Interfaces namespace are IRenderPackage, IGraphicItem, IGraphicDataProvider and TessellationParameters. All the other interfaces defined in Autodesk.DesignScript.Interfaces have been made internal or removed and they are no longer supported.
- If your application used IExtensionApplication interface from Autodesk.DesignScript.Interfaces namespace or related interfaces, then it is recomended to use Dynamo.Events.ExecutionEvents and Dynamo.Events.WorkspaceEvents class to get execution specific notifications as well as session parameters.

DynamoServices

1.1

The ITransformable interface has been introduced, this interface can be applied to a render package implemenation to provide users of those render packages with the ability to transform their geometry inside the visualization pipeline. For example, HelixRenderPackge as part of Dynamo Studio can make use of Transforms that a node author sets during tessellation. Note: this API is still in development and is a new addition post Dynamo 1.0, currently it requires using reflection to make sure it exists to avoid breaking backward compatibility with Dynamo 1.0. see this entry for more information: here

1.0.0

ExecutionEvents and WorkspaceEvents have been moved to Dynamo.Events namespace from earlier DynamoServices namespace.
- The ExecutionStateHandler delegate is modified to pass session objects of type IExecutionSession defined in Dynamo.Session namespace. Hence the GraphPreExecution and GraphPostExecution events on ExecutionEvents class are impacted with this change.

CoreNodeModels

2.0.0

Public default constructors have been added for CombinatorNode types to facilitate serialization.

1.0.0
