1 :: Tell me where can the helper class be used?
.NET (helper) classes can be used inside an orchestration.
2 :: Explain me is there a way to automate the process of adding assembly in GAC?
Yes. Right click the project, go to properties and select Build Events
And add following in the Post-Build event command line:
"C:Program filesMicrosoft Visual Studio 8SDKv2.0BinGacUtil.exe" -u $(TargetName)
And add following in the Post-Build event command line:
"C:Program filesMicrosoft Visual Studio 8SDKv2.0BinGacUtil.exe" -u $(TargetName)
3 :: Please explain what is the difference between a Document Schema and a Property Schema?
A document schema is used to define a message. It is a definition on an Xml message with optional extensions for flat files, EDI file, etc that enable the parsers to convert the native format into Xml.
A property schema is used to define message context properties. These can be of type MessageDataPropertyBase (the property value is promoted or demoted from/to the message itself) or MessageContextPropertyBase(property value only exists within the message context and can be set by adapters, pipelines or within orchestrations).
If you wish to promote a field from a message into the message context, then you need to define a document schema and property schema. In the document schema, you promote the required field using the property schema to define the property type that will be used in the message context.

4 :: Tell us what is the difference between static, dynamic and direct binding?
Static binding specifies port address,
Dynamic gives address of the port at runtime,
Direct binding sends messages to messagebox.
Dynamic gives address of the port at runtime,
Direct binding sends messages to messagebox.
5 :: What is what is Rehydration?
When a message is received, or else when a timeout has expired, the orchestration engine can be automatically triggered to rehydrate the instance – it is at this point that the orchestration engine loads the saved instance of the orchestration into memory, restores the state, and runs its from the point it left off.
6 :: Tell me do you know what is a link in a Map?
A link specifies the basic function of copying data from an element or attribute in an input instance message to an element or attribute in an output instance. You create links between records and fields in the source and destination schemas at design time. This drives the creation, at run time, of an output instance message conforming to the destination schema from an input instance message conforming to the source schema.
7 :: Tell me what is a helper class?
A .net helper class with the context of BizTalk is a class (library) that can support an orchestration with extra functionality. It can enhance an orchestration in tracing, error handling, caching, and serialization/deserialization
8 :: Tell me there is a .net helper class which suits to a requirement (in Orchestration) of an application but it is Non-Serializable, how can it be used?
Below are the steps:
☛ Add Reference
☛ Make Orchestration as Long running
☛ Add Atomic Scope
☛ Add Expression shape
☛ Orchestration variable of class inside scope
☛ Instance of object inside the scope
☛ Call method

9 :: Explain me does BizTalk support synchronous communication?
BizTalk Server architecture is asynchronous for scalability reasons. However, the architecture of the BizTalk Messaging Engine enables exposing a synchronous message exchange pattern on top of these asynchronous exchanges. To do this, the engine handles the complex task of correlating the request and response messages across a scaled-out architecture by linking together a number of asynchronous message exchanges to expose a synchronous interface.
10 :: Explain what are the execution modes in a pipeline Stage?
A stage in a pipeline has an execution mode of either “All” or “First Match”, which controls the components that get executed if more than one component is added to a stage.
For stages with a mode of “All”, each component is called to process the message in the order in which they are configured in the stage.
For stages with a mode of “First Match”, each component is polled to indicate that it is the right component until a match is found, at which point the component that matches is executed, while the remaining components do not get executed.
