I am getting error: PageRequestManagerServerErrorException: The process cannot access the file 'C:\Users\myUsername\Documents\Visual Studio 2008\Projects\myProject\UploaderTemp\uploading.GUID.FileName.JPG.resx' because it is being used by another process.

 

I am programmatically creating the Uploader at runtime (if that makes a difference).

 

Also, is the temporary upload 'resx' file always created? and is it stored on disk? Can this feature be disabled?

 

Thanks in advance.
