Proposal: Adding a Simple Licence Key Check to C# Application
I propose to add a simple licence key check to your C# application by creating a new form with a text box for the user to enter the licence key. The code will then send a query to your MySQL database to check if the key exists, and if it does, the application will open. If the key is invalid, a message box will prompt the user to enter a valid key. I will insert the code snippet into the existing application and test the application thoroughly. I estimate that the project will take 1 working days, which includes the modified C# application and a report documenting the modifications and testing results. I am confident that I can deliver you this in no time.
