Example: To enable reverse engineering from an existing database does not work #99

adayIvey · 2015-12-23T17:11:07Z

https://github.com/aspnet/EntityFramework.Docs/blob/master/docs/getting-started/full-dotnet/existing-db.rst

The example to enable reverse engineering from an existing database does not work:
Scaffold-DbContext -provider EntityFramework.MicrosoftSqlServer -connection "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;"

when I tried this is vs2015 I get

The term 'Scaffold-DbContext' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:19

Scaffold-DbContext <<<< -provider EntityFramework.MicrosoftSqlServer -connection "Server=sqldev\sqltest;Database=IveyCore;Trusted_Connection=True;"
- CategoryInfo : ObjectNotFound: (Scaffold-DbContext:String) [], CommandNotFoundException
- FullyQualifiedErrorId : CommandNotFoundException

Did you install the EntityFramework.Commands package? That is the package that brings in that command.

BTW, best to view the docs at http://docs.efproject.net/en/latest/ as they are RST. GitHub partially renders them as MarkDown... but you don't get all the content.

Yes i did install the commands

Couple more questions:

What type of project is this in?
Did you close and re-open Visual Studio (on occasion I have seen Package Manager Console get the wrong security policy, which prevents the commands from loading).

adayIvey · 2015-12-23T23:32:45Z

I tried this in a class library and a console app.

Using the latest 4.x framework

For you, are the steps to reproduce as simple as:

File -> New -> Project...
- Select .NET Framework 4.6.1 from dropdown
- Windows -> Console Application
- Click OK
Tools -> NuGet Package Manager -> Package Manager Console
- Install-Package EntityFramework.MicrosoftSqlServer.Design -Pre (installs 7.0.0-rc1-final)
- Install-Package EntityFramework.Commands -Pre (installs 7.0.0-rc1-final)
- Scaffold-DbContext -provider EntityFramework.MicrosoftSqlServer -connection "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;"

If so, there must be something specific to your installation. A couple of initial questions to help narrow things down:

Can you run Get-ExecutionPolicy in Package Manager Console and see what it returns. Sometimes when commands don't work it's because the execution policy gets set to Restricted.
What version of VS do you have? Help -> About Microsoft Visual Studio - the latest version would be 14.0.24720.00 Update 1.

Also just confirming that these are not ASP.NET 5 class libraries/console apps... since Package Manager Console commands do not work with those project types yet.

I will try when i am back in the office in the new year.... thanks

I am having exactly the same problems.
I have followed the steps above except that I am creating a WinForms application.
Get-Execution returns RemoteSigned,
I am using VS 2015 version 14.0.24720.00 Update 1.

The only thing of note is that on executing the Install-Package EntityFramework.Commands -Pre command, it shows a Red error "Cannot bind parameter 'FilterScript'..." but continues and eventually says "Successfully installed 'EntityFramework.Commands 7.0.0-rc1-final' to ".

Update…

I installed PS v4 amd that looks to have fixed my issue.

But while running Scaffold-DbContext I got error ‘The given key was not present in the dictionary.’

This looks to be a known issue dotnet/efcore#3861
Do you know if there are plans for a rc2 or a work around for this issue?

@bricelam we do require PS 3.0 right?

@Aday12345 - Regarding #3861 that is fixed and will ship in RC2 (planned for next month). In the meantime you could get out nightly builds that include the fix https://www.myget.org/Gallery/aspnetvnext

Yes, upgraded to PS4 and all seems to be fine now :-)
Many thanks.

Andy

rowanmiller · 2016-01-04T19:31:13Z

Great - I have #103 our for review to add this as a pre-requisite

rowanmiller · 2016-01-04T19:31:44Z

Thanks all for your work getting to the bottom of this one

bricelam · 2016-01-04T19:50:19Z

we do require PS 3.0 right?

Yes, it's required by our module. Our module should fail to load without it; I wonder if the error is getting swallowed/hidden by NuGet...

adayIvey · 2016-03-11T14:55:33Z

do you know when we will see RC2????

bricelam · 2016-03-11T17:40:14Z

@Aday12345 No, but when we do, it'll be posted here.
