Hi, I'm developing an Ajax-based application which makes heavy use of server calls to a WCF layer that communicates with a DB.

How can I handle such concurrency problems?...

Also, an UpdateProgress (maybe with an overlying semitransparen...
Is it possible to deliver an Excel Spreadsheet via an Web Service. I believe not as ASP.NET web services seem only to deal in Serializable elements which the excel binary format isn't (I think).

However, when the receiving page reads the POST value, if there is a + sign in the Base64 string, it is being replaced with a line break. For example: ...AABDEDS+DFEAED... becomes ...AABDEDS DF...

And each one implements IDisposable.Dispose, and overrides Finalize(). There is no base class, so each just extents Object. Dispose sets each private var to Nothin...
