Ensure...

1. You're using the .NET Core SDK 2.0
2. You ran dotnet restore on the project
3. You cded to the project's (*.csproj) directory

[mehtanilay10]

Yes, i am using 2.0 SDK and tried for dotnet restored on project but still got same error.

[mehtanilay10]

I am uploaded entire solution on github. CodeFirst is a project, which i want to Migrate and generate error.

[smitpatel]

Align your package versions.
Either use preview1 packages or preview2. Mix of those are not supported.

[smitpatel]

Also to use dotnet ef correctly, you need to install Microsoft.EntityFrameworkCore.Design package.

[mehtanilay10]

Added Microsoft.EntityFrameworkCore.Design and also change all to packages to preview1 still facing same error!

[smitpatel]

Does running dotnet build pass?

[mehtanilay10]

yes, project build successfully. But gives only error for CLI

[bricelam]

...and you're certain dir lists your *.csproj and dotnet --info says 2.0.0?

[bricelam]

(I know these are stupid questions, but I honestly have no idea what could be going wrong.)

[bricelam]

You may need to follow up on dotnet/cli. Something is going wrong before the EF code gets a chance to run.

In the directory D:\EntityFrameworkCore\EntityFramework\CodeFirst
dotnet restore
dotnet ef
and it worked.

I had to remove PackageTargetFallback due to this NuGet/NuGet.Client#1495 and I could not find where AssetTargetFallBack is set.

[mehtanilay10]

@smitpatel Thanks a lot for solving this issue ;)
Finally it was removed error from CMD but when i am using package manager in VS 2017 15.3 it gives same error. May be this is VS's Issue.

[smitpatel]

By default Package Manager Console (PMC) is rooted at dir containing the solution file.
dotnet ef requires to be operated in directory containing csproj file. The only way to invoke dotnet ef in PMC, you need to manually cd into the correct folder where your csproj file is located. Changing anything else in PMC has no effect current directory.

For best user experience, use PMC commands for EF (Add-Migration & friends) in PMC.

[timpur]

I has this issue and like to share.

i had the Microsoft.EntityFrameworkCore.Tools.DotNet as <PackageReference> because i uesd the GUI package manager to install it.

when i changed it to <DotNetCliToolReference> and then dotnet restore, this fixed it.

eg Use:
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
Not
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />

[JeanVanDenderFlume]

That last thing worked for me
In my case i had to change both \library-management\LibraryData\LibraryData.csproj and \library-management\Library\Library.csproj from to

My God, this library mangement is from github, orginally a core 1.1 web app I hope realy with 2.0 and webpack things will be stable and change too much.

[AliBayatGH]

This worked for me:
The EF tools for the CLI are provided in Microsoft.EntityFrameworkCore.Tools.DotNet. To install this package, add it to the DotNetCliToolReference collection in the .csproj file, You have to install this package by editing the .csproj file; you can't use the install-package command or the package manager GUI. You can edit the .csproj file by right-clicking the project name in Solution Explorer and selecting Edit XXX.csproj.

<ItemGroup>
  <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
  <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />

[veneMarcos]

I hade the some trouble and I fix this change the Microsoft.EntityFramework.Tools.Dotnet from the First <ItemGroup> like this:

 <PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />

For a second <ItemGroup> tag represent the DotNetCliToolReference:

<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />

Is there is a simple way to use this commands or have a good tutorial?

[amazingankur]

I have just started playing with .Net Core. I am running into issues with
dotnet ef migrations add Initial. I am using Docker for sql server but when I run the command I get following error: Specify which project file to use because this contains more than one project file.
When I remove docker-compose.dcproj, it runs fine but sql server migration generates exception as it doesn't get docker to instantiate DataContext.
On contrary, if I remove *.csproj, it says no executable found matching command.
Need help!

[amazingankur]

An error occurred while calling method 'BuildWebHost' on class 'Program'. Continuing without the application service provider. Error: Cannot resolve scoped service 'SportsStore.Models.DataContext' from root provider.
No application service provider was found.

[jlenriquez]

@amazingankur Where you able to solve your problem? In any case you still have issues with IDesignTimeDbContextFactory, make sure your DataContext class has a default constructor with no parameters in it. The migration script uses the parameterless constructor during execution.

[TLBSoftware]

I experienced this issue as well

Just like what @AliBayatGH @veneMarcos @timpur mentioned it appears as if the
dotnet add package Microsoft.EntityFrameworkCore.Tools.DotNet
command is adding the package as a PackageReference to the 2nd Item group in *.csproj. When this package is moved to the 3rd item group and the tag changed to "DotNetCliToolReference" the problem is solved.

[jlenriquez]

To those who may stumble this page looking for answers I have provided codes here in github that can be cloned: https://github.com/jlenriquez/SpikeSQLiteEF_OSX

The sample code can be run step-by-step by commenting/uncommenting necessary steps and can be used as learning reference.

[bricelam]

The EF Core .NET Command-line Tools docs may also be helpful.

[josephkandi]

I fixed this by adding this to my <Project Name>.csproj file

<ItemGroup>   
 <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0" />   
 <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" /> 
</ItemGroup>

This line was already there, <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0" /> . I only added the second line.

After that then restore the packages by running dotnet restore

[tttrrryyyyeer]

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.0.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.2" />
  </ItemGroup>

[ravensorb]

I followed this thread and am getting the following

Unable to resolve service for type 'Microsoft.EntityFrameworkCore.Scaffolding.IScaffoldingProviderCodeGenerator' while attempting to activate 'Microsoft.EntityFrameworkCore.Scaffolding.Internal.CSharpDbContextGenerator'.

Any thoughts?

[smitpatel]

@ravensorb - You are mixing packages from 2.0 & 2.1 release. Please make sure all packages from EF Core are on same release cycle include EFCore.Tools

[plasticalligator]

This is how I feel about having to install multiple NuGet packages and then manually modify my project configuration file to get the EF toolset, only usable by console, with no UI integration within Visual Studio.

[JonatanWang]

Go to the folder where .csproj is and run “dotnet restore" first

[rodrigorf]

Expliciting changing to my csproj folder and running "dotnet restore" worked for me. First i confirmed if my PackageReference and DotNetCliToolReference were correct, i had two add two missing references. Thks

[DongLei-tw]

you might miss the CliToolReference references:

<ItemGroup>
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0" />  
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" /></ItemGroup>

[webhay]

I have done something worked for me:
1- First dotnet publish your app.
2- Change the execute permission on the .dll in my case I have done: chmod 777 filename.dll
3- Use nano to remove the .sh script \n\r from all the lines.
It should work or might work :)

[imclint21]

After adding this :

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.0.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.2" />
  </ItemGroup>

It works !

Entity Framework Core .NET Command Line Tools 2.0.0-rtm-26452

[oising]

My problem was that my dotnet executable was the 3.0.0-preview version, but the EF project that had the design package installed in it was 2.2. So, I dropped a global.json into the solution root to force 2.2 and then dotnet ef worked from the root of the solution. I didn't even need to be in the project that had the NuGet package.

[aswanevelder]

@oising was the answer for me, using 3.0.0-preview but creating 2.2 projects.

dotnet new globaljson --sdk-version 2.2.204

[TomasHubelbauer]

I'm using the newly released .NET Core 3.0 with packages in the CSPROJ all being 3.0 but dotnet ef doesn't work for me.

Edit: to @bricelam's answer below, I found documentation for this in https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet#ef-core-3x.

[bricelam]

dotnet tool install -g dotnet-ef

[dinob68]

Also to use dotnet ef correctly, you need to install Microsoft.EntityFrameworkCore.Design package.

I have that and all above and still have no dotnet ef option when I do dotnet -h and get same error when I issue dotnet ef

[dinob68]

dotnet tool install -g dotnet-ef

None of the above worked. Here is my proj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>

after I run dotnet tool install -g dotnet-ef, like:

You can invoke the tool using the following command: dotnet-ef

I still see no ef tool when I run dotnet -h

Having said that, I am not sure this is good solution, shouldn't ef tool be in project folder version rather than global version?

[smitpatel]

@dinob68 - I am not able to understand why would dotnet -h would show anything EF specific.

[bricelam]

dotnet tool list will show the tools you’ve installed

[bricelam]

@dinob68 Think of it like a test runner. You don’t need to use an exact version of the runner or use a specific version of the testing framework. One runner will work with multiple versions of the test framework, and more than one version of the runner can be used with the same framework.

[Rafael955]

dotnet tool install -g dotnet-ef

This worked for me, thanks.
