Consuming Services in .NET by Example

This is a self-paced GK Digital Learning product. GK Digital learning products are created by world-class production and instructional design teams to deliver an experience that feels more like a classroom than traditional e-learning with hands-on activities for real-world results. In addition to high quality video content and hands-on labs you will have access to subject matter experts to ask questions for feedback and support.

In this course, three different approaches to consuming web services using the .NET Framework and C# are covered. In each scenario, you will explore a publicly available web service and create a small application that utilizes the service in a fun way. More specifically, you will see how to leverage classes such as WebClient and HttpClient in our existing applications. You will also make use of the "Add Service Reference" feature in Visual Studio to generate service clients for us automatically.

This online learning event is comprised of Articles to read, Labs to participate in, Videos to watch and all the time you have access to Mentors that will help you better understand the approaches to consuming services. We estimate that the learning event will take you around 2 ½ hrs to complete.
