I am confusing if entity framework 5 is based on .net framework 4.5 or .net framework 4.0 in my project, because when I added ef5 to my project from nuget, it shows the run time version is v4.0.30319 as in attached image. (I assume it should be v4.5.50709?)
In the project settings, the targeted framework is correctly set to .Net Framework 4.5 and I am using visual studio 2012.
If it is not using .net framework 4.5. How I can do to make sure it is using .net framework 4.5? Thanks for your help.
There is no 4.5 Runtime. The 4.5 Framework is built ontop of the 4.0 Runtime and CLR. What you are seeing is expected.

I have a asp.net core web api project with .NET Core 3.1 target framework. This project uses Microsoft.EntityFrameworkCore -Version 2.2.6. I migrated the entire web api project from .NET Core 3.1 to .NET Core 6. The project compiled fine including its dependencies without any issues. I did minimum validations and found no issues .I still wanted to know is it mandatory to migrate Microsoft.EntityFrameworkCore from 2.2.6 to 6.0
Can anyone provide their guidance regarding this scenario?
It seems that PostSharp.Patterns.Diagnostics.dll is not available for .NET 3.5.
I'm unable to use logging on .NET 3.5. Switching to .NET 4.0 works fine; however I need to target .NET 3.5.
When on .NET 3.5 the logging smart tag is also not available.
Is this the expected behavior?
PostSharp Pattern Libraries are not supported on .NET 3.5.
On the other hand PostSharp Aspect Framework (core of PostSharp) and PostSharp Architecture Framework are supported.
I am rather confused about the behaviour of Nuget Package manager and Entity Framework. As far as I have been seraching, Entity Framework supports only version 3.5 in .NET 3.5 (which was shipped with the .NET SP1). However, when I run Nuget Package it offered me to install EF 5 and today (upgrade to) EF 6.0.1. I am using Visual Studio 2010 and the project is a class library with target framework .NET 3.5.
My questions:
a) Can you use EF 5 or 6 with .NET 3.5? - My answer is no as well as some other answer in here.
b) How is it possible that Nuget offers me to download these versions?
c) I downloaded EF 5 with Nuget and it worked. How is that possible? (Even on EF website they say it is only for .NET 4.0 and higher)
We, the Entity Framework team, decided not to fix this issue (See Work Item 1341)
Only the version of System.Data.Entity.dll that ships with .NET Framework 3.5 will work with projects that target .NET Framework 3.5.
Trying to use Visual Studio 2012, Entity Framework 5.0 database first approach to generate my edmx.
When I generate the EDMX from the database VS 2012 - says
Successfully registered the assembly 'System.Data.Entity, Version=4.0.0.0;
web.config file as well says
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral.../>
I see EntityFramework and System.Data.Entity both listed in the references. EntityFramework shows up in the packages folder and System.Data.Entity points to the .NET 4.5 install folder. Does this mean that I am succesfully using EF 5.0?
For existing project migrations - when I migrate a project from VS 2010 .NET 4.0 and set the .NET client profile to 4.5 the System.Data.Entity assembly gets upgraded to the one in .NET 4.5 install folder. I do not see the EntityFramework.dll at all. Are there any changes I would need to make in order for my existing project to mgirate to EF 5.0 and .NET 4.5
Am I missing something here?
The version of System.Data.Entity.dll assembly is the same on both .NET Framework 4 and .NET Framework 4.5. The catch is that only one version can be installed on a machine at the same time so even if you target .NET Framework 4 in your project but run your app on a machine with .NET Framework 4.5 you will effectively run it against .NET Framework 4.5 (and therefore the EF5 version of System.Data.Entity.dll assembly).
With regards to EntityFramework.dll - up to the version 6 it was build on top of System.Data.Entity.dll (in EF6 the code from System.Data.Entity.dll and EntityFramework.dll was merged and further evolved). If you used EntityFramework.dll in VS2010 it means that it had to be one of the 4.x versions which were EF4. You could continue to use it even with the EF5 version of System.Data.Entity.dll but you will not be able to take the advantage of new features introduced in EF5 (like enums, spatial etc.). Since you decided to move to .NET Framework 4.5/EF5 you should also update your EntityFramework.dll 5.0.0.0. To do that you have to install the NuGet extension (http://docs.nuget.org/docs/start-here/installing-nuget) if you have not already and just install EntityFramework.dll using the package manager console (http://www.nuget.org/packages/EntityFramework/5.0.0). It should replace the 4.x version you have in your project with 5.0.
I'm trying to use Autofac with my current application but I'm using the .NET 3.5 and the NuGet package only works with the .NET 4.5.
What is the best (or latest) release that I can use with ASP.NET and .NET 3.5?
If my eyes work correctly, this list shows that Autofac 2.6.3.862 is the latest stable release for .NET 3.5.
