Does ClosedXML resolve OpenXML's package issue when writing excel files greater than 10MB?

Aug 22, 2014 at 12:44 PM

When writing an excel file greater than 10MB in size on a web server I sometimes get an System.IO.IsolatedStorage.IsolatedStorageException. Reading up on this it appears this is because when the file becomes greater than 10MB internally the packaging switches to isolated storage and isn't thread-safe...

Would using ClosedXML get me round this issue ?

ClosedXML doesn't use FeedData so you should be in the clear. That and the fact that nobody has ever complained about it.

I'd say test it and let us know.
