Can you please provide the structure of both the tables as there might be some stuff that will generate different ids .. E.g Table name = Cutomers --> CustomerId is auto generated column in both the databases For record #1 Customer id= 1 When C# application runs it will copy the Customer information,but due to auto generated column it will generates a different if in online database that might be a problem for other stuff. Please message me so that w could discuss in details.

Hello, I am interested in your project, because i have done similar syncing recently from local sqlite to remote mysql and local mysql to remote mysql. Let me introduce my self first. I am an experienced full stack developer, with an original background of .NET development. Later i started developing web projects in laravel, PHP. I have recently developed a point of sale system for my client which has desktop app developed in .NET and web backend developed in laravel. The desktop app works with a local mysql db in offline mode, then after some interval we post partial chunk of data to laravel api, to avoid primary key duplication issues (in case of distributed system) we use guids. Coming to the cost, it will depend upon number of factors, 1. Number of tables you want to sync ? 2. Whether the structure of local and remote db will stay same or they can very ? 3. Do you already have some backend api ? 4. Your local data will be one machine or will come from different machines (like POS) ? 5. Finally, what is the current structure of your tables, are you using guids or primary keys ? Let me know if you think i can assist you in this project. Regards, Muhammad Shafeeq

Hi There, To sync local and online DB server you would need a dedicated synchronization service and changes to your application as well. There is no out of the box synchronization service which can sync two ways online to offline and offline to online simultaneously. I had developed similar synchronization service for marine domain where data is entered on merchant ships and syncs with the shore office and vice versa. Let's connect over chat to discuss more.

Hello Sir, I can help you with the sinchronization bewtween your 2 databases. But I need more info about the size of the database... If it is a very large database my bid would rise a bit, the complexity would increase. If you are interested let me know. Thanks, Alex

Hello there! I am Vinícius, I've two year of experience in .NET platform, developing desktop Apps, mainly ERPs. The most applications i work utilize SQL Server as DB, which I mastered. Final year as graduating of Software Engineering Bachelor. The Project in my conception need to allow, both the source and the destiny of sincronism, to be changed any time, as well as define what tables and DBs will be synchronized. Do you would like an App that synchronizes when is executed ? Or in a specific set time? Do you would like an Interface for the App? Or a console application then would solve your needs. I make myself available for any change and discussion about a solution that meets all your and your employees needs.

Hi. I think i can do this job without any app. We can link the server together and make some stored procedures to copy your data locally. I have 2+ years experience in sql server databases.

Hello, I'm Juan Pablo Villa, software engineer from Azul, Buenos Aires, Argentina. I'm .Net Sr. developer, expert in C#, SQL Server, MVC Core, SSRS, SSIS, Azure VM/Database, EF, GIT. I was in several similar project, but I need more information about the tables, and the SQL server versions. We can use C# program, but it could be easier and more effective a SSIS package that migrates the data. I just start with freelancer, and I need a reputation best regards Juan Pablo Villa
