I tried DeepSeek to design a simple video conversion program in C#. I gave it some instructions and it generated code in less than a minute. Unfortunately, it was full of errors. For example, it generated code in Visual Studio 2019, even though the latest version is Visual Studio 2019. The code was based on .NET Framework 4.7.2, even though the latest version is .NET Framework 9.

It took a long time to fix the errors because some code is no longer used in the latest version of Visual Studio or has been replaced. However, overall, I've tried other AIs, such as Bolt, which were better at programming, but they also weren't without bugs.
