WPF ResourceDictionary中的StringFormat XamlParseException

Question

我有一個定義的樣式ResourceDictionary中具有與綁定的StringFormat如下一個控件模板：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat={}{0:N2}, FallbackValue=0.00}" /> 

我在本地運行，一切都很好，但我做了編譯和安裝在服務器上我得到以下異常，當我啓動任何世界糧食計劃署屏使得使用資源字典的：

System.Windows.Markup.XamlParseException: 'Unexpected token after end of markup extension.' Line number '224' and line position '148'. ---> System.Xaml.XamlParseException: 'Unexpected token after end of markup extension.' Line number '224' and line position '148'.

我做了一些挖掘和得到它由{}改變ResourceDictionary中的StringFormat工作{0：N2}到N2 ：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat=N2, FallbackValue=0.00}" /> 

其放於用戶控件以下工作：

<TextBlock Text="{Binding TotalCash, Mode=OneWay, StringFormat={}{0:N2}, FallbackValue=0.00}" /> 

我的問題是，爲什麼在用戶控件相同的StringFormat工作，但不是資源字典？我很高興它正在工作，但想知道爲什麼。

這是一個WPF bug。我猜你已經在開發機器上本地安裝了.NET 4.5（因爲可能安裝了Visual Studio 2012），而不是在你的服務器上（它只有.NET 4）。因此，您的服務器沒有Microsoft向.NET 4.5中的WPF添加的錯誤修正。
