Hello,

MAUI uses the API provided by Microsoft.Extensions.Logging for logging operations. According to its documentation, this Package does not provide operations for writing to files.

• Logging in C# and .NET.

For your needs, you'll need to extend Logger with methods that can support writing to files, or use some third-party logging package that supports MAUI. Due to Q&A policies, I can't recommend specific packages.

Best Regards,

Alec Liu.
