Hello
I understand that you want to convert your application language from English to French. I have read your application requirements document carefully and understand it. You just want to change language means no need to change existing application feature, right?
Let me know whether my understanding is correct?
Please share your existing application access with us so that we can understand better.
We are a team of software developers who work on Microsoft technology stack like C#.NET, ASP.NET, VB.NET, SQL Server, WPF, WCF, SharePoint, MVC etc.
Other skills- HTML5, CSS, JQuery, Bootstrap, JavaScript.
We can schedule a chat/call for further discussion.
Thanks,
Smita
