Deleting package file just after file is downloaded is throwing `The process cannot access the file because it is being used by another process. about downloader HOT 2 CLOSED

The downloader service has never taken the address of the package file that it is currently using. The downloader only needs the package object to continue downloading, which you serialized to binary or Json and deserialized from and this has nothing to do with my library because I only use the object from you. Check your application to make sure you have disposed of the stream reader and add FileShare.ReadWrite | FileShare.Delete to your FileStream when store the package serialized data on disk.

Note: in the C# just enough to add using keyword in the first of stream definition line to call Dispose() method and in the streams Dispose() method first call Close() and it calls Flush() methods.
For example:

using var serializedStream = 
         new FileStream(formattedPath, FileMode.OpenOrCreate, FileAccess.Write, FileShare.ReadWrite | FileShare.Delete);

Note2: If you use the FileInfo to create a file so you must be dispose of it after creating, like:

var fileInfo = new FileInfo(...);
if (fileInfo.Exists == false) {
    fileInfo.Create().Dispose();
}

Oh... My bad. Yeah I should Dispose fileInfo. Thanks!
