Choosing a file

To select a file to save, it is required to set the right properties of the service and then make a call to the DetermineFile method:

var saveFileService = GetService<ISaveFileService>();
saveFileService.Filter = "C# File|*.cs";
if (saveFileService.DetermineFile())
{
    // User selected a file
}
