Silverlight Application

Hello. I live in Russia the city of Tomsk. I have started to study IronPython in the browser and have addressed to your site (http://ironpython.net). Has established SilverLight 4, Silverlight 4 SDK, IronPython 2.7 and the environment of working out SharpDevelop 4.0. I study the documentation (http://ironpython.net/browser/docs.html). There are some questions. If you answer me them I to you I will be very grateful. I carry out examples from the instruction: 1) file index.html ---------------------------------------------------------------- Silverlight Application ---------------------------------------------------------------- Also I receive an error: ImportError: No module named unittest Tried different archivers (winrar, winzip, even pkzip.exe) 2) file index.html ---------------------------------------------------------------- Silverlight Application ---------------------------------------------------------------- I receive: XamlParseException: 2263 There was an error. [Line: 0 Position: 0] MS.Internal.XcpImports.CreateFromXaml(String xamlString, Boolean createNamescope, Boolean requireDefaultNamespace, Boolean allowEventHandlers, Boolean expandTemplatesDuringParse) MS.Internal.XcpImports.CreateFromXaml(String xamlString, Boolean createNamescope, Boolean requireDefaultNamespace, Boolean allowEventHandlers) System.Windows.Markup.XamlReader.Load(String xaml) Microsoft.Scripting.Silverlight.DynamicApplication.LoadComponentFromString(String xaml) Microsoft.Scripting.Silverlight.DynamicApplication.LoadRootVisualFromString(String xamlString) Microsoft.Scripting.Silverlight.XamlScriptTags.<>c__DisplayClass2.b__1() Microsoft.Scripting.Silverlight.XamlScriptTags.Load() Microsoft.Scripting.Silverlight.DynamicApplication.DynamicApplication_Startup(Object sender, StartupEventArgs e) MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args) MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName) I start examples so: 1) I start console DOS 2) I do flowing the example catalogue 3) I start "D:\PFiles\IronPython 2.7\Silverlight\bin\Chiron.exe"/b 4) I carry out in the browser index.html Or from SharpDevelop 4.0 environment, result one.
