Hi,
I have Visual studio.NET 2005 on XP proffessional
Is it possible to me to use LINQ and ADO.NET Entity Framework?
Can LINQ and ADO.NET Entity Framework be used with express editions
as well?
Thanks in advance.

I wanted to try out the ado.net entity framework model and see how it was
different from linq to sql entities. I put a page in a web application
project, added an ado.net entity model and told it to generate the model
from existing database, went back to my empty page and put a GridView on it.
I right clicked on the GridView and went to show smart tag. I went to choose
a datasource combo box and pressed down arrow once (to create a new...

I'm about to begin a brand new, big, ASP.NET project (using 3.5 .net fw), VS
2008. I'm using MySQL as the backend (customer request.) I have absolutely
no experience with LINQ and/or the Entity Framework. Though I am quite
comfortable with ADO.NET and VB.NET.
In your opinion, should I take a few days and learn it and utilize these
technologies in this new project (I'm starting from scratch)? Are the
benefits worth it in your opinion?...

different keys are mapped to the same row. Ensure these two mapping

Hi,
I have an Entity data model built in Entity Framework, which sources data
primarily from an MS SQL 2008 database, and sources some static (data
dictionary) values from code-based objects. I know I *could* store the data
dict values in SQL: for various reasons that's not the path I want to take.
I have some lookups, which are based on code-based Objects. They are
encapsulated in Objects because the values can change during...

I have to learn how to do one or the other: linq to sql or ado.net entity
framework. There will be overhead no matter what way I go since I don't know
either one. Which one would be the best one to use overall?

I have about 12 services that will be used on the website I am working on. A
few of them are News, Events, Venues (that work directly with Events),
Mailing lists and some others. Each one of these services will have some
classes and enums that are contained in a namespace of their own. When it
comes to the data access (entity framework), I need to know how to design
the model. Do I just put all of the database objects in a single model, or...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
