When using the command in the package manager console window in VS2017 Professional
Scaffold-DbContext "server=server;uid=username;pwd=password;database=database" IBM.EntityFrameworkCore -force

I'm encountering the following exception:
System.MissingMethodException: Method not found: 'Void Microsoft.EntityFrameworkCore.Scaffolding.Internal.CSharpDbContextGenerator..ctor(Microsoft.EntityFrameworkCore.Scaffolding.IScaffoldingProviderCodeGenerator, Microsoft.EntityFrameworkCore.Design.IAnnotationCodeGenerator, Microsoft.EntityFrameworkCore.Scaffolding.Internal.ICSharpUtilities)'.
at IBM.EntityFrameworkCore.Scaffolding.Internal.Db2CSharpDbContextGenerator..ctor(IScaffoldingProviderCodeGenerator providerCodeGenerator, IAnnotationCodeGenerator annotationCodeGenerator, ICSharpUtilities cSharpUtilities)
It should be noted that there is another project in the same solution also using EntityFramework Core for SQL Server that is generating the DB Context fine with the Scaffold-DbContext command.

I am using specflow with xunit and i am facing the issue as if i right click and run one selenium test case from the test explorer, all the other test cases also runs and both run twice.

i have tried removing packages folder from users/nuget folder and build again but that also did not helped..
However i did not faced this problem with Nunit
SpecFlow.Plus.LivingDocPlugin is a plugin for Specflow not Xunit. If you need to use both Specflow plus and Xunit you should also include the main Specflow libraries needed to interface with Xunit.
SpecFlow
SpecFlow.xUnit
SpecFlow.Tools.MsBuild.Generation

I am able to run the command
Add-Migration
in my package manager console
However I am not able to run the command
Script-Migration
as I get the error message
Script-Migration' is not recognized as the name of a cmdlet
After upgrading from Entity Framework Core 1.1. to Entity Framework Core 2.0 I can access the command.
I upgraded my ASP.NET Core, EF Core class library solution to Visual Studio 2017.
However when I want to run migrations commands like Add-Migration I get the following warning.
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework\Update-Database' for Entity Framework 6.
However I don't have EF 6 installed

This can happen if you previously had an EF6 project open in VS. To unload EF6, you can use the following command.
Remove-Module EntityFramework
I followed the official Microsoft tutorial for Entity Framework Core database first approach available in this link.
When I try to execute the below command to generate the model from the database:
Scaffold-DbContext "Server=Data Source=DESKTOP-COJD62N;Initial Catalog=TrainGameDB;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -context TrainGameContext -Verbose
I am getting the following output:
Build started...
Build succeeded.
dotnet exec needs a managed .dll or .exe extension. The application specified was 'F:_IIT Level 6\UX\CW2 Backend\App2\TrainGameAPI\src\TrainGameAPI\bin\Debug\netcoreapp1.0\TrainGameAPI.runtimeconfig.json'
Process finished with non-zero exit code
