Is it possible to open MVC2 project in Visual Studio 2012? When I try to load the project I get this error :
De\De.csproj: The application which this project type is based on was
not found. Please try this link for further information:

Do I need to upgrade to MVC3 or I can keep my project in MVC2?
At VinnyG's request I am providing a link to an answer I provided on how to fix this issue. The linked answer provides a fully detailed solution but here is a summary:
ASP.NET MVC 2 will need to be downloaded and installed. The MVC 2 project file will need to be modified removing its project GUID. The removal of the project GUID will mean that the project no longer behaves like an MVC project: no right click to add view, controller, etc., but will compile and work as an MVC 2 project without having to migrate.

If the Model-View-Controller (MVC) project uses version 3 or 4, you can open this project in Visual Studio 2012. By default, Visual Studio 2010 with SP1 supports only MVC 2 and 3, and Visual Studio 2012 supports only MVC 3 and 4. For information about how to automatically upgrade from MVC 2 to MCV 3, see ASP.NET MVC 3 Application Upgrader. For information about how to manually upgrade from MVC 2 to MVC3, see Upgrading an ASP.NET MVC 2 Project to ASP.NET MVC 3 Tools Update. If your project targets the .NET Framework 3.5 with SP1, you must retarget your project to use the .NET Framework 4.

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?
I am creating a bot using Microsoft Bot Framework and the project is using .NET Framework 4.6.1. I am also creating another project for user interface using .NET Core. Since both projects will be using same database so I am thinking to create an another common project using Entity Framework Core. But this project will not be working with .NET Framework 4.6.1.
Could anyone suggest me how to implement this requirement ?
I recently did a portion of the MVCMusicStore tutorial using MVC3 as directed. However, being that I have Visual Studio 2012, I'm attempting to use EF in an MVC4 application. I was attempting to add the using System.Data.Entity; directive and it was not found.
I know that I can probably just add the reference to it. But I'd like to know why it's not already available for my MVC4 project. Is there a new method of creating an Entity Framework supported application using MVC4?
Entity Framework is now being distributed separately from Visual Studio through the NuGet package management system as of Visual Studio 2012. The reason for this is to decouple EF from the release of VS, so it can be released on a different time schedule. They have also recently released EF as an open source framework, so it's being removed as a project from the .net framework release.
You have to use NuGet to install Entity Framework in your project. Right click on the project and choose Manage Nuget Packages. Make sure you select the Online tab in the dialog that opens, then in the search type Entity Framework and click Install. You will then be able to add the using statement.
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'm working on a project with Entity Framework in Webmatrix 2 RC, so I need to use Entity Framework v.5 RC because of conflicts between previous versions and .NET Framework 4.5.
The two ways I know to install NuGet packages in Webmatrix are from the NuGet Gallery on the Webmatrix ribbon and from the package manager in ASP.NET Web Pages Administration: either solution proposes only Entity Framework v4.3.1.
I have downloaded Entity Framework v.5 RC with the Package Manager Console of Visual Web Developer and copied the EntityFramework.dll into the bin folder of my project.
This solution works but I wonder if exists a way to install a not recommended NuGet package that doesn't require the use of Visual Web Developer.
You can use nuget.exe or NuGet Package Explorer, both are standalone and lightweight. You'll still have to manually add references to the files though.
