The file is in use by IIS Express Asp.Net

I've an image in asp.net application and I resize and convert it for several times , but sometimes it's used by IIS Express process. and I can't resize or convert it. How to free IIS Express handle or how to bypass it? is engaging IIS Express before publishing normal or I should exactly handle such situation?

this piece of code is for replacing two images:

public static void Replace(string OldPicture, Stream NewPicture)
{
   Bitmap OldImage = new Bitmap(OldPicture); 
   ImageFormat format = OldImage.RawFormat;
   Bitmap NewImage = new Bitmap(NewPicture);
   OldImage.Dispose();
   NewImage.Save(OldPicture, format);
   NewImage.Dispose();
   return;
}

Oldpicture is in use while saving via NewImage.save

It's happen if the File is open. Possible you have to call .Dispose() or work with using(...){...}.

Dispose Example:

Bitmap source = new Bitmap(filePath);
Rectangle croptRect = new Rectangle((int)cropX, (int)cropY, (int)resizeWidth, (int)resizeHeight);
Bitmap target = source.Clone(croptRect, source.PixelFormat);
source.Dispose();
// working ...
target.Dispose();

Using Example:

if (!File.Exists(_path)) using (File.Open(_path)) { }
