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

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
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.

Microsoft .NET Framework 4 Client Profile

I changed from Vista to Windows 7.  Every time I start my computer it says I need to install Microsoft .NET Framework 2.0  When I do that, the installation says it's already in my computer. I have looked and what's installed is Microsoft .NET Framework 4 Client Profile.  What should I do?  Also, my bluetooth has stopped working. Is this why?

Net Framework 4.0 Slowed XPSP3 Boot Time To A Crawl!

Ok Guys  Net Framework 4.0 showed up in my updates. So I installed it and rebooted. My machine took almost 4 minutes to reboot. I am running XP Media Center SP3, 4gb DDR2 Ram, Intel Pentium D Processor @ 280 ghz. Everything was workinf perfectly ans fast until this time it only took 45 to 60 seconds or so to boot. Wallpaper shows up then forever before anything else besides volume control.  Went back and uninstalled net Framework 4.0 and back up to speed with no problems and boots like normal. No one on any of the forums I have visited have had an honest answer. I have seen numerous posts about this problem with boot times and most have gotten a run around from microsoft techies. Saying it did not install right and to try from here or there to reinstall it. All to no avail. It is so hard to get microsoft to admit they have a problem on a new introduction of a product. Can anyone tell me the truth here and are you working on a fix or patch? Thanks Dale

I have the 1st of the two programs (above), and wondered if I should have it (the, "Client Profile" version); or instead, should uninstall it, and download the 2nd (above), the one (without, the words "Client Profile")?  OR, are they essentially the same?  I'm an intermediate computer user but don't have alot of experience with deciphering between the types of .NET Frameworks (like the 2 above).  Anyone familiar with this area, please advise.  (P.S.:  I never actually went to the download center and downloaded the (1st) item (above).  I just noticed it is installed (under, installed programs).

Microsoft .Net Framework 4 Client Profile installation error: (0x800B010B), "Generic trust failure "


I'm currently using a window 7 64 bit operating system fujitsu laptop and I've been trying to install a update: 'Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2160841)'. However, upon many tries of installing the update, i still couldn't get it install. The error details for the update is Code 66A.

Therefore, after searching on Windows forum for solution for that error, i've tried to repair the Microsoft .Net Framework 4 Client Profile by following these steps:

A. Click on Start and click on Control panel.

B. Go to Program and Features.

C. Scroll down to Microsoft.Net Framework 4 Client Profile, right click it.

D. It will give you a choice of Uninstall/Change, click it.

E. Then, it will give a choice to repair.

After following the above steps, the repair did not succeed because: Generic trust failure.

UI on the Fly: Use the .NET Framework to Generate and Execute Custom Controls at Run Time


Creating UI controls on the fly can be accomplished via run-time code generation. And there are lots of reasons to do so. Generating these controls once and then reusing them as needed is more efficient than generating the controls each time. Read on.

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.

Slow page load during a list query one time during the day


We have a monitoring tool set to check to see if the home pages for our 3 web apps load in under 60 seconds every 10 minutes.  All 3 web apps load in under 3 seconds on every 10 minute check except for one exception.  One check every day one of the web app's home page takes longer than 60 seconds to load.  This happens at 11:45PM when there is very little user usage on the environment.  The characteristics of this page are as follows: The only thing on the page is a list view web part which was added by the browser.  The page has not been customized with SPD or code at all.  The list that it pulls is a simple links list that has 281 items on it.  The view pulls all 281 items and displays them in sets of 100.  I cannot find any associated event in the server events and/or SharePoint ULS logs nor are there any daily sharepoint timer jobs running at that time.  Our full index happens at midnight with incremental happening hourly.  Our enviroment is 2 WFEs, 1 App/indexer and we have a separate SQL cluster backend.  

Could someone lead me possibly in the direction I should take next in my troubleshooting?   

Slow load time of custom assembly on x64 compared to x86.

I am developing an application that automatically generates assemblies using the CSharpCodeProvider (.Net Framework 3.5).  These assemblies contain a single class with a very large number of local variables and methods.  After compilation I create an instance of this class (using Activator.CreateInstance) to be used elsewhere in the application.  When the application is deployed on a 32-bit system (tested on Win 7 Prof 32-bit and on Win XP) the CreateInstance method returns after 1 or 2 seconds, i.e. it first JITs the assembly before creating the instance.  However, on a 64-bit system (tested on Win 7 Home 64-bit, Win Server 2003 64-bit and Win Server 2008 64-bit) CreateInstance takes up to 5 minutes to return. Is there any reason why it would be that much slower on a 64-bit machine? I have tried many different options when compiling, such as setting the platform to x64, using the /optimize flag, etc, but none of these have made a difference. I also tried calling PrepareMethod on all the method in the class.  When I do this in the 32-bit environment, it takes approximately 10 seconds.  In the 64-bit environment it takes more than 3 minutes. As a last resort I tried ngen before constructing the object, but this made no difference in the execution time.

How to keep my Workflow alive only during the time my client application is running ?

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

Time difference : Hosting Server and client

hi All,I have asp.net/c# web project. How to manage the time difference between the server and clientFor instance, I am at India, and Server is located at UK. So if do any activity, like "comment on friend's photo" etc. the time stamps is UK's time. So if do some activity from India at 10.00 AM, the time stamp would be 5.00 AM. So if the user who sees his activity at 10.00 AM sees it as if it was done at 5.00 AM.If user whom he acted upon (like friend whose photo got the comment) too see 5.00 AM. this is ok if the friend is at UK, but causes confusion if he was at other time location like Australiahow to handle this

Error: ASP.NET Ajax client-side framework failed to load.

Getting some errors after implementing the calendar control.  Error: ASP.NET Ajax client-side framework failed to load.  Here are some screenshots of the relevant info:   Here's the scenario...  I compile code locally, view the pages in a browser locally, and it all works fine.  Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on my machine), and gets these errors when viewing my locally compiled code.  He then compiles the same code on my machine again just for a test, but still gets the same errors.  Can anyone come up with any good reasons for this behavior?  I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific.  Tried doing that with the same results.  Help!        

Project builds for .NET 4.0 but not 4.0 Client Profile

Hi, I'm converting some class library projects from .NET 2.0 to 4.0. I've gone through the wizard to get the solution and projects into Visual Studio 2010 and it builds. When I open the project properties for any of my class library projects and set the target framework to .NET 4.0 it still builds, but if I change it to .NET 4.0 Client profile, which is what I want, it doesn't. What is confusing me is that the errors are that a referenced namespace in one of my own class libraries doesn't exist. E.G. I have a class library named IGLT.SMO.Data. Its default namespace is IGLT.SMONET.Data with several classes in that namespace. A second class library named Common references IGLT.SMO.Data and uses it throughout. When I change Common to target .NET 4.0 Client Profile I get errors like "The type or namespace 'SMONET' does not exist in the namespace 'IGLT' (are you missing an assembly reference?)".   I'm not missing a reference or it wouldn't build for any framework. What am I missing?
