Efcore: Migrations: CLI Tools: Honor ASPNETCORE_ENVIRONMENT

Representative of the script I'm using when I encounter said bug.

SET ASPNETCORE_ENVIRONMENT=Test
dotnet ef database update

env.EnvironmentName does not not seem to be aware of ASPNETCORE_ENVIRONMENT when running the second command. Instead, it is always set to Development.

@Eilon , Where's the best place to track this?

[Eilon]

Bug might not be in EF, but at least we should start the investigation here.

[mgolois]

did you try using "Setx" instead of "Set"?

We don't currently honor the ASPNETCORE_ENVIRONMENT environment variable. You should be able to get it working by using the following.

dotnet ef database update --environment %ASPNETCORE_ENVIRONMENT%

[Eilon]

@bricelam should we add support for that env var? It's a bit gross to tie the two together, but it's also a very common scenario to use EF in ASP.NET.

[bricelam]

We should definitely consider it.

[Eilon]

I love definite maybes! 😄

Any plans to address this and start taking into account ASPNETCORE_ENVIRONMENT by any chance? The EF Core docs recommend setting this env variable which is a bit confusing since it's not being used (see tip green box

[bricelam]

It has worked since version 2.0.0-preview1. Note, if you're using PowerShell, the syntax to set an environment variable is different than command prompt:

$env:ASPNETCORE_ENVIRONMENT = 'Production'

[univhack]

That's great news thanks for the update @bricelam!

I'm writing $env:ASPNETCORE_ENVIRONMENT = 'Production' in Package Manager Console and then running Update-Database but still gives the same warning "No Migrations were applied". It is still not respecting to my ASPNETCORE_ENVIRONMENT.

@mrtgr Can you please file a new issue and include a runnable project/solution that demonstrates the behavior you are seeing?

I have recently had a problem with EF tool not using connection strings from my "appsettings.Production" file, it Turns out that if EF Tool has trouble with the "appsettings.Production"(E.g null string) , it will revert to using appsettings. I have not been able to see this written to the console by the EF tool, but using the "-verbose" flag with database update, the environment will be written to the console. Just wanted to mention this as I have not seen this documented anywhere.
