04 Απριλίου 14 12:54 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

at System.IO.Path.GetInvalidPathChars one reads: The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names note: can also call this method from non-trusted Silverlight app – not as Intellisense tooltip wrongly says in Visual Studio 2013 with Silverlight 5.1 I just found […]

Gotcha: Silverlight’s Uri class constructor eats up part after last slash
