C# - Know About The Best Framework Available For App?
Apr 1, 2010
I am trying to design a new application which basically aims at providing biometric authentication services. What I want to do is that the app will present the user with an interface where the user can get his eye scanned for authentication. The most important feature I want to incorporate is that the user need not have a webcam, the app must be able to read the eye from the display device i.e. CRT or LCD screen itself.I want info about the best framework available for this. Once successfully tested, I am planning to provide it as a webservice.
I host a website that has recently been upgraded from .NET Framework 2.0 to .NET Framework 4.0. Within the website, I have an instance of BlogEngine which still requires .NET Framework 2.0. Each website is in it's own application pool. My issue is that when I browse to the blog portion of my website, I receive a 500.19 error with the following information...
The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration The web.conf file that is listed in the error message is the config file that belongs to my root website which is running .NET Framework 4.0. How do I get the two websites to run together in the same website using different versions of the .NET Framework?
I have this cenario:One server (machine) that have framework 3.5. And one site (website) developed for framework 3.5.This site can not be modified (rebuild in other FW version, or others changes).

And continue have sites working with other frameworks version?Or, should I develop my new webapplication in framawork 3.5 ?If I can install the framework 4.0, do I need make some specify configuration during the installation?

Is there a way to export a EF 4.0 Data Model to EF 3.5?
I looked around and found that we are not able to access EF 4.0 from a ASP.Net 3.5 project here: [URL]
Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.
I have two questions, could anybody please answer to those:1) Do I need to install Dotnet framework 2.0 if dotnet framework 3.5 is already installed on the same server?2) Also do I need to install "ASP.NET 2.0 AJAX Extensions 1.0" if higher version is installed on the same server?

Say I have .NET Framework 2.0, 3.0, 3.5 installed for an Asp.NET web application. I realize that Framework 3.0 and 3.5 are just extensions to Framework 2, what is less clear is how 3.0 and 3.5 interrelate. Am I safe uninstalling Framework 3 if the Asp.NET application targets 3.5?
can I use .net framework 4.0 in VS2008 ? If yes how can I do that? My application uses 2.0 ,Or are there advantages to updating to the latest .NET 4.0 now? And also I came across some new features in framework 4.0 like :
