Develop one desktop application in C# for HTTP POST request and response

Overall: The job is to develop, in its most simplistic architecture, one Desktop application in C#, for POST request and responses. (1) The application will login to a server. (2) The login credentials will be read from a config file. (3) If login is successful, The application will ask "which request?" (4) User will input the request XML: There are might be basically six requests depending on the user's input: - login_server request - send_order request - info_order request - cancel_order request - modify_order request - info_positions request (5) The application will then get the response XML (that the POST will return), and parse it, and get the relevant fields in the XML, and return it in one tidy format. **** Accordingly, there will basically two basic methods in the architecture: - post_request method: (that will make one of the requests listed above using the correct XML input, and, return the response XML) - parse_response method: (that will basically get certain fields of the response XML. The application then print one tidy version of this XML as string on the screen.) **** Other requirements: - The requests should be POST. - All requests and responses should be in XML format. - There is a certain request format for XML. (The example will be provided in the documentation) - There is a certain format for response XML. (The example will be provided in the documentation)
