Start with Workbook.Load(String), Workbook.Load(Stream), and the CompoundDocument.Open/Read calls shown in the stack trace, then reproduce the failure with an .xls template in the reported ASP.NET scenario. Trace why CompoundDocument constructs a BinaryWriter over a non-writable stream; done means the template loads into a workbook without the “Stream was not writable” exception.
