XAML - using a constant in place of a string

XAML - using a constant in place of a string To keep code consistent, it can be useful to use constants rather than 'magic strings'.

In the XAML , add a namespace, to the Assembly and Namespace, that contains the class: <window ... ... xmlns:inf="namespace=MyApp.Infrastructure;assembly=MyApp.InfrastructureLibrary" > where: a. the C# class is in the namespace: MyApp.Infrastructure b. the C# class is in the assembly MyApp.InfrastructureLibrary 3. Now in XAML , instead of using a 'magic string': < ... prism:RegionManager.RegionName=" ContentRegion " /> you can reference the constant string: < ... prism:RegionManager.RegionName="{x:Static inf:MyConstant...

Hosting a proxy in an ASP.NET or SharePoint application - limits of NTLM (double hop issue) and how to overcome

Hosting a proxy in an ASP.NET or SharePoint application - limits of NTLM (double hop issue) and how to overcome ISSUE: If you host a proxy page (ASHX) in ASP.NET or in SharePoint, and the target server is a different machine, and the target server requires Windows Authentication , then you should know that NTLM has a restriction, where it cannot pass credentials on the 'second hop' from the proxy to the target server, unless it has an explicit username and password. this is called the ' double hop NTLM issue ' and is better documented elsewhere: http://blogs.msdn.com/b/besidethepoint/archive/2010/05/09/double-hop-authentication-why-ntlm-fails-and-kerberos-works.aspx note: if your application uses Negotiated (Kerberos) Authentication, and Kerberos is correctly setup, then my understanding is that Kerberos can handle the second hop from the proxy to the target server. if you *must* use NTLM (for example, if you must deploy to an existing SharePoint Web App), th...
