The EntityFramework package is not installed on project

Viewed 79422

I am having trouble getting the EF to install on my very simple project called 'Match' (just now learning MVC, better late than never). The general context here is that I created the Model class with only 2 fields and now I want to change the Model class to have a few more fields/properties. I have made the change in the Model class and am now trying to update the DB to match. I am trying to use Update-Database from EF to do that.

PM> install-package EntityFramework You are downloading EntityFramework from Microsoft, the license agreement to which is available at http://go.microsoft.com/fwlink/?LinkId=253898&clcid=0x409. Check the package for additional dependencies, which may come with their own license agreement(s). Your use of the package and dependencies constitutes your acceptance of their license agreements. If you do not accept the license agreement(s), then delete the relevant components from your device. Successfully installed 'EntityFramework 5.0.0'. Successfully added 'EntityFramework 5.0.0' to Match.

Type 'get-help EntityFramework' to see all available Entity Framework commands.

PM> Enable-Migrations Get-Package : A parameter cannot be found that matches parameter name 'ProjectName'. At C:\Users\Dave\Documents\Visual Studio 2010\Projects\Match\packages\EntityFramework.5.0.0\tools\EntityFramework.psm1:611 char:40 + $package = Get-Package -ProjectName <<<< $project.FullName | ?{ $_.Id -eq 'EntityFramework' } + CategoryInfo : InvalidArgument: (:) [Get-Package], ParameterBindingException + FullyQualifiedErrorId : NamedParameterNotFound,NuGet.PowerShell.Commands.GetPackageCommand

I have just restarted Visual Studio and it worked.

In my case I had a project that for some reason did not have a Packages.config file. The result was I got the error mesage "The EntityFramework package is not installed on project xxxx".

To solve this simply add a Packages.config file and "Install-Package EntityFramework" then works.

I have the same problem. I have added EFCore to a project that has installed EF6. so add-migration xx command performed with EF6 instated of EFCore and I get this error. removing EF6 and restarting Visual Studio solved my problem.

I have experienced with that issue I solved it by just install Microsoft.EntityFrameworkCore.Tools nuget package

that package will Enable these commonly used commands: Add-Migration Drop-Database Get-DbContext Get-Migration Remove-Migration Scaffold-DbContext Script-Migration Update-Database

In My Case reinstall Entity Package and restart Visual Studio.

should work if you are opening a project for the first time,

second click on the console project and "Set as stratup project"

install EntityFrameworkCore install EntityFrameworkCore.SqlServer And Then Close Visual Studio And reopen Problem Fixed

You can also clear cache NuGet in VS. resolved my problem

In my case, I have a Xamarin.Forms solution with three projects - Backend (for Azure Database connection), one common library, an iOS project and an Android project. The error messages that I have received were "The EntityFramework package is not installed on project ..." and "No context type was found in the assembly ...". I have solved it by setting Backend as my StartUp project and then by entering the commands in the following format in the Package Manager Console:

Enable-Migrations -ProjectName Backend -Verbose

and after that

add-migration -ProjectName Backend Initial

I hope that this is of help for someone :)

This problem can be related with conflict of two versions of EntityFramework and EntityFrameworkCore. For checking it, you can write: Get-Module in package manager console. If you see EntityFramework and EntityFrameworkCore together, you need to delete EntityFramework or dependecy that linked on EntityFramework. For searching dependency you can use search solution input in solution explorer. After deleting dependency or EntityFramework you need to restart project.

I will also add that closing and opening Visual Studio solves this problem for me. As of the time of writing this, this issue occurs on Visual Studio 2022.
