WinForm - Spawn a process that simulates the user double clicking on the file

Dim fileName As String = "MY_FILE"
Dim process = New System.Diagnostics.Process()
process.StartInfo = New System.Diagnostics.ProcessStartInfo() With { _
	.UseShellExecute = True, _
	.FileName = fileName _
}
process.Start()

or a short hand version

System.Diagnostics.Process.Start("My-file-name.ext");

Note the user must have the appropriate program to open the file (e.g. Adobe Reader for PDF, MS Word for .doc/docx, etc)

Web

string responseFile = Server.MapPath("~/" + FileName);


Response.ContentType = "text/xml";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + FileName);
Response.TransmitFile(responseFile);
Response.Flush();
