Migrations, quick
|
|
=================
|
|
View > Other Windows > Package Manager Console
|
|
Default project: DataLayer
|
|
Startup project: DataLayer
|
|
since we have mult contexts, must use -context:
|
|
Add-Migration MyComment -context LibationContext
|
|
Update-Database -context LibationContext
|
|
Startup project: reset to prev. eg: LibationWinForms
|
|
|
|
|
|
Migrations, detailed
|
|
====================
|
|
if only 1 context present, can omit -context arg:
|
|
Add-Migration MyComment
|
|
Update-Database
|
|
|
|
|
|
Migrations, errors
|
|
=================
|
|
if add-migration xyz throws and error, don't take the error msg at face value. try again with add-migration xyz -verbose
|
|
|
|
ERROR: Add-Migration : The term 'Add-Migration' is not recognized as the name of a cmdlet, function, script file, or operable program
|
|
SOLUTION: add nuget pkg: Microsoft.EntityFrameworkCore.Tools
|
|
|
|
|
|
SqLite config
|
|
=============
|
|
relative:
|
|
optionsBuilder.UseSqlite("Data Source=blogging.db");
|
|
absolute (use fwd slashes):
|
|
optionsBuilder.UseSqlite("Data Source=C:/foo/bar/blogging.db");
|
|
|
|
|
|
Logging/Debugging (EF CORE)
|
|
===========================
|
|
Once you configure logging on a DbContext instance it will be enabled on all instances of that DbContext type
|
|
using var context = new MyContext();
|
|
context.ConfigureLogging(s => System.Diagnostics.Debug.WriteLine(s)); // write to Visual Studio "Output" tab
|
|
//context.ConfigureLogging(s => Console.WriteLine(s));
