ASP .NET Web Service or ASMX Web Service provides the ability to build web services that send messages using the Simple Object Access Protocol (SOAP). SOAP is a platform-independent and language-independent protocol for building and accessing web services. Consumers of an ASMX service do not need to know anything about the platform, object model, or programming language used to implement the service. They only need to understand how to send and receive SOAP messages.

I this course we are going to first learn how to create a web service. We will then learn how to consume a web service in an ASP .NET Web forms application. In this course we are going to create four projects in total. Two projects will be projects for will be of ASP .NET Web Service and the other two will be client projects of ASP .NET Web forms which will consume the web services web methods. The first web service project will be basic where you are going to learn the concepts of ASMX web services. The second project of a web service , you will create and advanced web service of personal finance records. In this project we are going to implement CRUD operations to MSSQL database. We will further implement account registration and sign in functionality.
