Aspnetcore.docs: tutorials/razor-pages-mac/model add tip

[jmoral4]

If your build complains of "Could not load file or assembly 'Microsoft.EntityFrameworkCore'..." then type:
"dotnet add package Microsoft.EntityFrameworkCore" (and probably Microsoft.EntityFrameworkCore.Design) into a terminal to fix the dependency issues.

@jmoral4 thanks for the tip. I'll get this added next update.

[nlpsl202]

Why I do step by step same as the tutorials
but when Register the database context
the UseSqlite always red
and
dotnet ef migrations add InitialCreate
dotnet ef database update
always Build failed

[Rick-Anderson]

@nlpsl202 you are missing an include. You can't do a migration if the project doesn't build.

It's missing a step:
dotnet add package Microsoft.EntityFrameworkCore.Sqlite

[shauntif]

Also I had to put in the cli tools rather than just a package reference.

netcoreapp2.1

<DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.4" />

I really don't understand why the dataContext is required in order to scaffold pages. What we use repository that uses web service as backing store?

[digitalohm]

i had to run at least:

dotnet add package Microsoft.EntityFrameworkCore
dotnet add package Microsoft.EntityFrameworkCore.Sqlite

in order to get this to build

When I try to run the update databse command I get:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 35 - An internal exception was caught)

Fixed in unified version
