Issues that this hotfix rollup fixes

Issue 1

The System.Windows.Markup.XamlWriter.Save method can’t turn off indentation for an element that contains an "xml:space='preserve' line. This line adds spaces added to the element. For example, a paragraph that is represented by the following XAML will be transformed into incorrect XAML by the XamlWriter.Save method:

XAML representation of the source paragraph:
<Paragraph><Span><Run Text="Test"/></Span><Run Text=" "/></Paragraph>
Incorrect XAML created by the XamlWriter.Save method:
<?xml version="1.0" encoding="utf-16"?><Section xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"><Paragraph xml:space="preserve"><Span>Test</Span> <Run> </Run></Paragraph></Section>
Expected (correct) XAML:
<?xml version="1.0" encoding="utf-16"?><Section xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"><Paragraph xml:space="preserve"><Span>Test</Span> <Run> </Run></Paragraph></Section> 

Issue 2

Some content is missing in printouts if the transparency is used on Windows 7 and earlier versions. For example, some content in a table border could be missing and result in a blank area in printouts.

Issue 3

Some content is blurry in printouts if transparency is used in Windows 7 and earlier versions. This occurs even when you set the print to photographic level quality.

This hotfix improves the output quality that is obtained by using the OutputQuality.Photographic value. Be aware that documents that have better quality require larger print spooler files and longer wait times. If these side effects aren’t desirable, you can adjust the output quality of the print.

Issue 4

When you run a Windows Presentation Foundation (WPF) touch application under the system context in Windows 7 and Windows Vista, touch functionality is lost and a crash may occur after several minutes. This issue occurs because inking is not supported in the system context in Windows 7 and Windows Vista.

This hotfix disables touch support while under the system context. Touch-to-mouse promotion still works.

Issue 5

When a WPF application uses a TreeViewItem object outside the context of a TreeView, the application can encounter an InvalidCastException that has a stack trace starts as the following:

System.Windows.Controls.VirtualizingStackPanel.FindScrollOffset(Visual v)
Note This exception occurs when the TreeViewItem object is in a virtualized list control, such as a ListBox, DataGrid, or ListView, that tries to find the scroll offset of the TreeViewItem object or one of its descendants. For example, if you declare a TreeViewItem as the root of a DataTemplate, and the DataTemplate is used as the CellTemplate of a DataGrid column, this exception occurs.

Issue 6

This hotfix enables Transport Layer Security (TLS) 1.1/1.2 for SQL Server connectivity in System.Data.dll.
