Simple chat app using WPF MVVM

How long will it take you to finish the job? if the software is going to work on local network then it can be done in 3 to 4 days. otherwise if the project should work over the internet then it will take about 10 to 15 days. of course my bid is different for this scenario. Proposal: i'm a PHD student in Computer Science. the only thing is that I don't know if you want to use your software over your local network or on the internet. If your plan is to run the project on your local network then two software must be developed. one software will act as a server and will be placed on one of the computers on your local network that is accessible to others and client softwares will send and receive messages through the connection to server app. for the database, an sql server can be used to store data. if your plan is to use the software over the internet, then mysql server is used for DB, some PHP APIs must be developed to fetch chat history. in order to provide the security for API, each user must be registered in the system and a Token management system must be developed to secure the API. and for sending and receiving chat messages WebSocket can still be used.

Hello. I can do it for you in short time. I think WCF could be used. Server side can be hosted as windows service (or simple console app if you want). Server will notify clients if new message arrived, so no need to use polling at client side. As DB we can use SQLite or something more useful, as ORM we can use dapper or entity framework (supper preferable). Contact with me over chat for any details.

How long will it take you to finish the job? This job can take 10-15 day. This will depend on the final software architecture that will be used. If the project remains as simple as it is, then it can take a maximum of 10 days. The cost will still be 12500 indian rupee but it will vary according to project complexity and size. Proposal: Hello, I hope you are doing fine. About me, I am a professional software developer with more than 4 years experience in developing software for both small and medium sized businesses. The skills that I posses are as follows; Web development skills (php, js, css,html), Software Development Skills (c#, java, c/c++, python), Mobile App development skills (android, windows) and User Interface and design skills. I read through your project description very carefully and I am interested in doing this project. I currently don't have an ongoing project, hence I will spend more time in doing this project because it requires more time. I have made a LAN chat application before that used both video and voice in chatting. The system had a central server for submitting the requests i.e. for connecting the clients. The requests were handled by the server. According to your project, you want a chat application that also supports broadcast in group chats. Is the application going to run on the internet or LAN? This will influence the architecture of the final system. Will the users have accounts before using the application or they will discover each other online and then begin to chat? This will determine if the system will have a central server or not, the central server will store the accounts and connect users. If the system will have a central server then broadcasting will not be possible, instead, the messages will be sent to the group members by the server. That's my approach.
