Fiscalcode check by calling a webserver

Summary: - An interface is needed between an ERP System and a webservice for checking company fiscal status. - The request-response message system will be in a JSON format. - The code should be C#, Visual Studio 2010 compatible (the code will be integrated later in a C# application built in VS 2010). - The interface will need two functionalities: 1. First functionality: on a user interface a user must provide a company fiscal code (in a text box) and the user should be able to invoke the method for checking fiscal status (by pressing a button). The result from the webserver will be shown as a message window. 2. Second functionality: running the same webservice for checking several companies. Deliverables: - The user interface app installed on a test environment and instruction for installing on the go-live environment - The code / project solution - 1 month post-deployment free service if needed
