OPTION 1: UI
rt-clk project project > Publish...
click Publish

OPTION 2: cmd line
change dir to folder containing project
  cd C:\[full...path]\Libation\LibationWinForm
this will use the parameters specified in csproj
dotnet publish -c Release

OPTION 3: cmd line, custom
open csproj
remove: PublishTrimmed, PublishReadyToRun, PublishSingleFile, RuntimeIdentifier
run customized publish. examples:
publish all platforms
  dotnet publish -c Release
publish win64 platform only
  dotnet publish -r win-x64 -c Release
publish win64 platform, single-file
  dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true

transaction notes
-----------------
// https://msdn.microsoft.com/en-us/data/dn456843.aspx
// Rollback is called by transaction Dispose(). No need to call it explicitly
  using var dbContext = new LibationContext();
  using var dbContextTransaction = dbContext.Database.BeginTransaction();
  refreshAction(dbContext, productItems);
  dbContext.SaveChanges();
  dbContextTransaction.Commit();

aggregate root is transactional boundary
  // //context.Database.CurrentTransaction
  //var dbTransaction = Microsoft.EntityFrameworkCore.Storage.DbContextTransactionExtensions.GetDbTransaction(context.Database.CurrentTransaction);
  // // test with and without : using TransactionScope scope = new TransactionScope();
  //System.Transactions.Transaction.Current.TransactionCompleted += (sender, e) => { };
  // also : https://docs.microsoft.com/en-us/dotnet/api/system.transactions.transaction.enlistvolatile

pattern when using 1 db context per form
    public Ctor()
    {
        InitializeComponent();
        // dispose context here only. DO NOT dispose in OnParentChanged(). parent form will call dispose after this one has been switched.
        // disposing context prematurely can result in:
        //   The ObjectContext instance has been disposed and can no longer be used for operations that require a connection.
        this.Disposed += (_, __) => context?.Dispose();
    }
