Client Application Services - Role service cache time out bug

Hi All, For people using Client Application Services with WPF, be aware of this bug. You can configure the "cache time out" for roles to be fetched again from the service. (In the visual studio dialog, Properties -> Services -> Advanced) This means the roles are cached on the client (in a file). If the application asks for roles again, they are not fetched again for "cache time out" time. When you set this value, it goes into your App.config, transformed into seconds. So if you choose 1 minute, the App.config has: cacheTimeout="60".   However, when using the ClientRoleProvider (for instance to do something like clientRoleProvider.GetRolesForUser("SomeUser")), this cacheTimeOut is interpreted in Minutes, not seconds! To prove my point, check ClientRoleProvider.Initialize method:   string temp = config["cacheTimeout"]; if (!string.IsNullOrEmpty(temp)) _CacheTimeout = int.Parse(temp, CultureInfo.InvariantCulture);   Later on, in ClientRoleProvider.GetRolesFromDBUser (what's in a name?), you see: _CacheExpiryDate = cd.RolesCachedDateUtc.AddMinutes(_CacheTimeout);   Testing also shows this behavior. So be aware, and always put the value in minutes in your App.Config!   Regards, Koen

.NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.

Client script not running


Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>

The script, that shows menu items when the

CLR Inside Out: Improving Application Startup Time


Visual Studio is a wonderful development environment, whose IntelliSense®, integrated debugging, online help, and code snippets help boost your performance as a developer. But just because you're writing code fast doesn't mean you're writing fast code.

C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework


When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.

Web Security: Part 2: Introducing the Web Application Manager, Client Authentication Options, and Pr


This article, the second of two parts, continues coverage of Web security for Windows. It introduces the Web Application Manager in IIS that allows Web processes to be isolated, decreasing the security risk associated with running in a logon session. The article then picks up where Part One left off-it discusses authentication methods such as basic authentication, digest authentication, integrated Windows authentication, and anonymous logons, and the benefits and drawbacks of each.

Serial approval workflow keeps running


I have a serial approval workflow created out of the box. The setting cancell this workflow when the document is rejected is selected. But if one of the approvers rejects it the workflow keeps running. After this is it will give acces denied errors for the other approvers.

So for example what is happening. The workflow is started and sends a email to persone 1. This persone approves so the workflow sends a email to persone 2. Persone 2 decided to reject the document. Now i want the workflow to be cancelled, but it keep running and sends a email to persone 3 for approval. If persone 3 opens the workflow he get's a acces denied error, i guess because of the reject.

Anyone has a idea what is happening here?

Why does .NET Framework 4 client profile slow down boot time network creation?

I've been running a Windows XP sp3 KVM virtual machine for a long time now, and some recent update made the initial network startup go from a few seconds at boot time to around 90 seconds. Using Add/Remove program to uninstall recent updates points the finger at .NET Framework 4 client profile. With it installed, if I right click on network and ask for properties right after booting, there is a 90 second delay before the network dialog with the list of network interfaces finally appears. In addition, the network drive I have automounted at login is not accessible for the same 90 seconds. As an experiment, I tried going into the device manager and deleting the network interface, and if I reboot after that it takes 90 seconds for the new hardware wizard to appear. All these 90 second delays vanish if I remove this .NET update. The network comes up as soon as the system boots.

WCF Workflow Service Application - Required Extensions

Hello, I built a WCF Workflow Service App and I built a custom activity that requires an extension in the workflow. In a web app, I'm trying to create a service reference to the WCF workflow service but it says that an extension that is required has not been provided; so how do I consume a service with a required extension? At what point do I supply that extension in an ASP.NET scenario? Thanks. http://linkedin.com/in/brianmains

An ASP.NET 4 Web Application Using the SqlTableProfileProvider - Doable or a Time Sink?

Have hundreds of ASP.NET developers been wasting dozens of hours each on something that can't be made to work in ASP.NET? This is too weird! I've scoured the Web in vain looking for an example where someone has implemented the Microsoft SqlTableProfileProvider in an ASP.NET Web application . (The SqlTableProfileProvider  lets you store Profile data in a normal way rather than as difficult-to-manipulate blob data.) There are plenty of implementations using the Web site model, including fellow...(read more)

WCF - First call to Callback instance from Server takes considerable time to make it to the client.

Hello. There's a performance problem we are facing that we are unable to fix using DuplexChannels. The first call made by the client to the server reaches the server instantly. The first call made by the server to the first client using a Callback proxy will take several seconds to reach the client. All subsequent calls to the client (as well as other clients) will reach and execute instantly. The client connects to the Server using a proxy to IServiceProvision, supplies an instance to an implementation of IClientCallback and calls IServiceProvision.Start(). The server instantly processes the call and makes an asynchronous call to IClientCallback.DoWork(), which takes several seconds to enter the client's DoWork() implementation. The remainder of the execution then runs smoothly. Also, the server will experience such a slowdown only for the very first call of the first client that connects to it. Is it normal for the Callback interface to take so much time to warmup, only on the first call to the first client? Below is the full source code. Thanks for any information you may provide. Cheers Mike Shared Class Library using System.ServiceModel; namespace Test { [ServiceContract(Namespace = "http://test/IService", CallbackContract = typeof(IClientCallback))] public interface IServiceProvision { [OperationContract] void Start(); [OperationContract] void
