We’re excited to announce the release of .NET Core 2.1. It includes improvements to performance, to the runtime and tools. It also includes a new way to deploy tools as NuGet packages.
In summary, the most important issues here are:
public class AggregateRootBase : Entity, IAggregateRoot
{
private int _versionId;
public void IncreaseVersion()
{
_versionId++;
}
} internal sealed class OrderEntityTypeConfiguration : IEntityTypeConfiguration<Order>
{
public void Configure(EntityTypeBuilder<Order> builder)
{
builder.Property("_versionId").HasColumnName("VersionId").IsConcurrencyToken();
//...
}
} var order = await _ordersContext.Orders.FindAsync(orderId);
order.AddOrderLine(request.ProductCode);
var domainEvents = DomainEventsHelper.GetAllDomainEvents(order);
if (domainEvents.Any())
{
order.IncreaseVersion();
}
await _ordersContext.SaveChangesAsync();
de4dot is an open source (GPLv3) .NET deobfuscator and unpacker written in C#. It will try its best to restore a packed and obfuscated assembly to almost the original assembly. Most of the obfuscation can be completely restored (eg. string encryption), but symbol renaming is impossible to restore since the original names aren't (usually) part of the obfuscated assembly.
Supported obfuscators/packers
