I developed code in a single non-compiled .aspx page that ran great, but when I copy-pasted the code into a code-behind page the c# compiler is raising an error:
error CS1061: 'System.Collections.Generic.IEnumerable' does not contain a definition for 'Descendants' and no extension method 'Descendants' accepting a first argument of type 'System.Collections.Generic.IEnumerable' could be found (are you missing a using directive or an assembly reference?)
The line in question:
xdoc = System.Xml.Linq.XDocument.Parse(xmlReminders);
var xdocReminders = from reminder in xdoc.Descendants("Reminders").Descendants("Reminder") select reminder;
The compiler command references System.Xml.Linq.dll
csc.exe [...bunch of stuff...] /reference:C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\System.Xml.Linq.dll
and MSDN has this method in XElement's documentation:
Descendants(XName): Returns a filtered collection of the descendant elements for this document or element, in document order. Only elements that have a matching XName are included in the collection. (Inherited from XContainer.)
Why would the same code compile and run at run-time on the server, but not compile manually?
For reference, the compile command is:
