Breakpoint not hit in EF Core IEntityTypeConfiguration class on add-migration in PackageManagerConso-CodePudding

I am doing some discovery in a small test project and am trying to have a breakpoint hit in the configuration definition class.

public class TripExpenseComparisonEntityTypeConfiguration : IEntityTypeConfiguration<TripExpenseComparison>
{
    public void Configure(EntityTypeBuilder<TripExpenseComparison> builder)
    {
        builder.HasKey(u => u.Id)
             .HasName("PK_TravelExpense");

        builder.OwnsOne(vo => vo.BudgetedTripExpense, exp =>
        {
            var x = from p in exp.GetType().GetProperties() where p.PropertyType == typeof(decimal) select p;

            exp.Property(u => u.AllowNegatives)
                .IsRequired();

            exp.Ignore(u => u.TotalExpenses);

        });
       ... rest removed

When I run Add-Migration from the package manager console, in the DataAccess project, it runs the entire migration (correctly) EXCEPT it doesn't hit the breakpoint set on this line

>exp.Property(u => u.AllowNegatives)
        .IsRequired();

Do breakpoints not function in this type of class? Or do they not get hit during an add-migration event?

CodePudding user response：

You can add this line Debugger.Launch(); before the required place. It launches and attaches a debugger to the process.

See the documentation here.

Another option you run the migration using DbMigrator through code and debug.
