I need a WEBSERVICE for transactions with MySQL database and SQL Server. The WEBSERVICE should process transactions INSERT, UPDATE, DELETE and generate datareader and DATASET objects to queries via SELECT statement. It should also address the possible errors and return message to the user on failures in the operation. The WEBSERVICE can be consumed by WEB and MOBILE systems. The WEBSERVICE can preferably be written in VB.NET or C #. Also need a webform example where I can use all the features of the webservice.

Hello, Based on your description you need a web service (I suggest WCF) written in C# or VB.NET that is used as an access point for MySQL and MSSQL. To be accessible on any device mobile, web or desktop I suggest to make a JSON formated web service with REST to support INSERT,UPDATE,DELETE and SELECT operations. Regarding the connection to databases I can suggest to use Entity Framework but if you prefer direct connection and DataReaders I am OK with that too. I am available to discuss. Thank You, Patrik
