.Net framework 3.5 unable to upgrade

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :.NET Framework

I am running Windows 7 64 bit installed from an .iso mounted on a CD.  Since SP1 has been available, I have been unable to install it via Windows Update and directly downloading it from the website.

Recently I downloaded a program that required .Net 4.0 but was unable to install it as well.  I checked Windows Features (via Add/Remove Programs) and found .Net Framework 3.5.1 was turned off.  Clicking on it and both of its components (HTTP and non-HTTP) produces the error message: "An error has occurred.  Not all of the features were successfully changed."  Clicking on the .Net 3.5.1 alone will produce the same error.

Microsoft .Net Framework 3.5.1 does not appear in the Add/Remove Programs list, nor does any previous version of .Net Framework.

I used a .Net Framework Cleanup Tool to try and wipe 3.5.1 and start over.  I downloaded and successfully installed .Net 1.1.  .Net 2.0 reported that it could not be installed because a version of it was already installed in the OS.  .Net 3.0 reported that a newer version of the .Net framework was installed.  .Net 3.5's executable file opened but did not run.  After this, I used the .N

.net framework unable to install

Okay I've had absolute ____ with this program and if another program I used didnt require it I wouldnt bother with it because its not worth this hassle. I finally get 3.5 to downloaded after 4 days  which I was getting the same error for as I am now with that and I have no idea how I fixed it. I am not computer savvy in the least, so please assume I know nothing. Anyway thats not good enough need 4.0 .The error is I download the setup for .net framework 4.0 it lingers at about 5-10% approx and stays there the temp log says "A connection with the server could not be established"  And there in lies the problem since I am able to post this I'm clearly able to connect to something but not the microsoft download server. The os is vista and yes before its said I am running it as administrator. Any help/ideas on this issue would be greatly appreciated.

.net framework upgrade


Hello, I’ve been monitoring the installation of security patch [MS10-070] on my servers and noticed a couple of my Exchange 2007-sp2 servers did not receive the patch.  Looking closer I see it is because these servers are running .net v2.0 sp1 rather than v2.0 sp2.  These servers are running Windows Server 2003-sp2-x64.


Question: What is the most appropriate way to install v2.0 sp2 so that these servers will get the recent .NET security update? 

- Via a blocked [hidden] Windows Update [KB951847] (which will also install the .net v3.x/3.5 family).

Unable to Target 2.0 Framework in VS2010


I have been using VS2005 for some time to build VB.NET applications using the 2.0 Framework.  I recently installed VS2010 on the same machine and am using it to build 4.0 Framework VB.NET applications.  All the apps work fine, and AddOrRemovePrograms shows Frameworks 1.1 through 4 installed, including the "Microsoft .NET Framework 4 Multi-Targeting Pack".  BUT, I am unable to use VS2010 to build applications to run on the 2.0 Framework, and (mis?) understand that should be do-able.  I opened an incident with MicrosoftConnect in August ("Framework Multi-Target Woes in VS2010") and sent off requested information twice, but have no response now for a month.  Any help/advice would be greatly appreciated.

Here is some detail:

The NewProject dialog only shows [.NET Framework 4].

Unable to connect to Database | ASP.NET Membership and Entity Framework


Ok, so this is my first Solution using the Entity Framework (EF). Here are my steps so far:

1) Created Database named: BSA with an owner of username/password (AspNetServicesUser/password)
2) Created Entity Data Model (EDM) in a separate project (contained within the same solution)
3) Created an ASP.NET Web Application with basic functionality (new project within the same solution)
4) Added Reference to the EDM in Web App and added Connection String to the EF
5) Decided I wanted ASP.NET Membership added to the Web App
6) Configured SQL Server for Application Services using aspnet_regsql.exe on BSA database

Now, I need to know: 
a) How do I create the connectionString for the Web.config file in the WebApp?

Errors I receive:

I get this error using the ASP.NET Configuration Tool under the "Security" Tab:

Login failed for user 'AspNetServicesUser'.

I get this error using the ASP.NET Configuration Tool under the "Provider" Tab --> Select a single provider for all site management data --> Test

Could not establish a connection to the database. 

If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Creating a Generic Entity Framework 4.0 Repository

With .NET 4.0 right around the corner, I thought it would be cool to download Visual Studio 2010 beta 2 and start playing around with the next release of Entity Framework.

The initial release of Entity Framework came with a great deal of criticism. To make matters worse, there was a large uproar when it was rumored that Microsoft would be abandoning LINQ to SQL, in favor of Entity Framework. This was because, at the time, many developers felt Entity Framework was an inferior technology to LINQ to SQL. To set things right, Microsoft proactively moved forward with improving Entity Framework, in time for the 4.0 release of the .NET Framework. This is good news because my initial impressions, so far, have been nothing but positive.

ASP.NET 4.0 Dynamic Data and Many to Many Entity Framework Entities

I did not play much with Dynamic Data controls in VS2008 and just made a cool discovery in VS2010 Beta 2. This may not even be new, but as I'm sitting 30,000+ feet over the Atlantic ocean, I don't have access to VS2008 at the moment to check.

Entity Framework 4 Tips for WinForms Development

I've been recently working on a smart client (WinForms) application backed by Entitiy Framework 4 (EF4) on Visual Studio 2010. In this blog post I will try to give you some tips regarding some limitations and points to be careful about EF4.

Bar Code Scanners with the .NET Compact Framework

Summary: Learn how to make your applications use bar code scanners in a generic way-ndependent of the specific bar code scanners that are used on different devices. Using the design patterns Façade and Factory, the implementation not only supports multiple bar code scanners, but it also makes it easy to add support for other bar code scanners. After a brief discussion about bar code scanners and the bar code scanner pattern, a download code sample, written in C#, demonstrates the use of the pattern and technologies.
