Possible null reference argument for parameter 'path' in 'DirectoryInfo Directory.CreateDirectory(string path)'.

Non-nullable property 'DefaultImagePath' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Possible null reference argument for parameter 'path' in 'DirectoryInfo Directory.CreateDirectory(string path)'.

The switch expression does not handle all possible values of its input type (it is not exhaustive). For example, the pattern '""' is not covered.
