What are 3 basic WCF configurations required for hosting a WCF service or consuming from a WCF client?

What are 3 basic WCF configurations required for hosting a WCF service or consuming from a WCF client?

There are three types of hosting environments for WCF services: IIS, WAS, and self-hosting. The term “self-hosting” refers to any application that provides its own code to initialize the hosting environment.

Is used to communicate the error message from the service to the client in WCF?

Since a client’s concern area is not about how an error occurred or the factors contributing to an error, SOAP Fault contract is used to communicate the error message from the service to the client in WCF. A Fault contract enables the client to have a documented view of the errors occurred in a service.

How many types of binding are there in WCF?

You can define bindings in two ways: through code or through configuration. These two approaches do not depend on whether you are using a system-provided binding or a custom binding.

What is the difference between WCF and Web services?

Web services support only one protocol- HTTP and HTTPS during communication, but WCF supports more protocols like- HTTP, TCP, and MSMQ that can be extended for a comprehensive solution, reliable session, and transactions. It signifies WCF is more adaptable to work together for a variety of software.

Which type of contract is applicable to interface in WCF?

Service Contract
The Service Contract declares an interface in the WCF service for the client to get access to the interface. The Operation Contract declares a function inside the interface, the client will call this function.

How transactions are implemented in WCF services?

A transaction in WCF is a set of operations that follow some properties, collectively known as ACID. Here, if a single operation fails, the entire system fails automatically. When an order is placed online, a transaction takes place.

Which contract supports Transactionflow?

The binding used for Service 2 has transaction flow enabled, and the operation contract mandates the flow of the client transaction.

Which hosting mechanism is supported by WCF?

Hosting Mechanisms − Various activation mechanisms are there for WCF hosting, i.e., IIS (Internet Information Service), WAS (Windows Activation Service), Self-hosting and Windows Service, but a web service is hosted only by IIS.

Which are the types of bindings?

Types of binding

• Sewn binding. A strong, durable binding where inside pages are sewn together in sections.
• Glued binding. Also known as Perfect binding.
• PUR-glued. Content pages are glued with PUR glue, which offers superior adhesion.
• Lay-flat binding.
• Spiral.
• Spiral.
• Wire-o.
• Saddle-stitched.

What is difference between SOAP and REST WCF service?

Actually only the difference is how clients access our service. Normally, a WCF service will use SOAP, but if you build a REST service, clients will be accessing your service with a different architectural style (calls, serialization like JSON, etc.).

What transport protocols are supported in WCF?

The transport channel is the bottom-most channel of the WCF stack. The protocols that are typically used in this channel are HTTP, TCP, MSMQ, and named pipes, but WCF allows application developers to use other transports as well, such as Simple Mail Transfer Protocol (SMTP) or File Transfer Protocol (FTP).

What is the Java multithreading interview question?

This is a relatively tough Java multithreading interview question that serves many purposes. It checks whether a candidate can actually write Java code using thread or not. It sees how good a candidate is on understanding concurrent scenarios, and you can ask a lot of follow-up question based upon his code.

What are the problems with multithreading and concurrent programming?

Memory-interference, race conditions, deadlock, livelock, and starvation are an example of some problems that come with multithreading and concurrent programming. There is no end of a problem; if you get it wrong, they will be hard to detect and debug. This is mostly an experience-based interview question about Java.

What are the advantages of multithreading?

Multithreading provides better utilization of cache memory as threads share the common memory resources. Multithreading reduces the number of the required server as one server can execute multiple threads at a time. 8) What are the states in the lifecycle of a Thread?

What is this thread interview question?

This thread interview question is mostly asked in the first round or phone screening round of an interview and purpose of this multi-threading question is to check whether the candidate is familiar with the concept of “join” method or not.
