HowTo: change color of validation messages in ASP.net MVC
02 Νοεμβρίου 18 02:35 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια

Fix: VSIX installer error – SignatureDescription could not be created
10 Οκτωβρίου 15 02:13 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

This is my answer at: http://stackoverflow.com/questions/31552082/vsix-installer-signaturedescription-could-not-be-created-for-the-signature-algo/ to the question on why some extensions fail to install at RC (Release Candidate) versions of Visual Studio 2015, showing error “SignatureDescription could not be created for the signature algorithm supplied”.

If you use TimeUpDown control from Silverlight Toolkit in your XAML like below (copy pasting from CaptionGrid at ClipFlair source): <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <DataTemplate x:Key="StartTimeCellTemplate"> <TextBlock Margin="4" Text="{Binding Begin}" /> </DataTemplate> <DataTemplate x:Key="StartTimeCellEditTemplate"> <!-- <TextBox Margin="4" Text="{Binding Begin, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=true}" /> --> <input:TimeUpDown Format="hh:mm:ss" Value="{Binding Begin, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=true}" /> </DataTemplate> … </ResourceDictionary> [...]
