+Summary: XmlReader's Close dosen't close file the stream
+
+If you create an instance of XmlReader using XmlReader.Create(fileuri)
+method (instead of handing your own file stream), and then later me a call
+the Close Method on the XmlReader instance it dosen't acctualy close the
+internal filestream (untill the object gets garbage collected). This can
+lead to an IOException (Sharing violation) if you open it a second time
+(even after closing it explicitly).
+
+I've attached a test case tested it both on Mono (ubuntu package & current
+SVN) and on Visual Studio 2005. Visual studio does in fact close the file
+stream when the Close method is called.
+
+Test case
+using System;
+using System.IO;
+using System.Xml;
+
+namespace TestCase
+{
+ class XmlReaderCloseCase
+ {
+ static string test_file = "test.xml";
+
+ static void Main()
+ {
+ // XmlReader automaticaly creates a stream for us
+ XmlReader r = XmlReader.Create(test_file);
+ // But close really dosen't close the steam (at least in mono)
+ r.Close();
+
+ // Exception here (only on mono, not in MS's implementation)
+ XmlTextWriter w = new XmlTextWriter(test_file, null);
+ }
+ }
+}
