The feature needs to cover functionality as follows: The logarithmic axis has an exponent step (1, 10, 100, 1000) and the current ticks support of the axis only plots evenly distributed ticks. Clients, however, sometimes need to display unevenly distributed ticks (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and so on).

It seems that the System.Net.Http package dependency was added because it was required by SharpDX which was used by RadWebCam in older versions of Telerik. After the migration to SkiaSharp the package dependency was no longer needed, but it seems it wasn't removed.
Remove the System.Net.Http package dependency.

RichTextBox
Type:
Feature Request
Currently, when you insert a content control using TextProperties, CheckBoxProperties, etc., the applied font is the default one for the content controls. Instead, it should use the font of the associated span/paragraph where it was inserted. For example, if you type "Hello world" and set its font size to 36, then place the cursor between "Hello" and "world" and insert a textbox content control there, the font size of the textbox will be something like 10, instead of 36.
Synchronize the font properties and make sure that the content control uses same font as the existing paragraph/span.

RichTextBox

Feature Request
FormatException is thrown during the import of a table coming from a docx document when the application culture is "sv-SE". This happens when the column width in the document is a floating point number (ex: 120.65). The Swedish culture uses "," as decimal separator and " " as the number group separator, which makes any invariant decimal value (like 120.65) invalid during standard parsing (ex: float.Parse("120.65")).
Stacktrace:
FormatException: The input string '4514.5' was not in the correct format. at System.Single.Parse(String s) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.ImportTableGrid(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style style) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.TableImporter.Import(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildTable(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Parsing.Style parentStyle) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildBody() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.BuildDocument() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.MainDocumentImporter.Import()Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.ReadXmlContentAndRelationsFromPackage(Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxPartImporterBase importer) Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.Import.DocxImporter.Import() Telerik.Windows.Controls.RichTextBox.dll!Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider.Import(System.IO.Stream input)
To work this around, switch to InvariantCulture during the import and return the original culture after that.
var cultureCache = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture;
var provider= new DocxFormatProvider();
rtb.Document = provider.Import(stream);
Thread.CurrentThread.CurrentCulture = cultureCache;
Thread.CurrentThread.CurrentUICulture = cultureCache;

When developing live (localization/resource) display language switching for SL5, the LocalizationManager should allow to update all localization strings applied through the ResourceManager. In SL5 it's not possible to listen to an attached dependency property for all dependency objects. Therefore it would help to have a way to know when the attached ResourceKey dependency property changes (and on which DependencyObject) in the LocalizationManager.
