Sync Framework is a comprehensive synchronization platform that enables collaboration and offline access for applications, services, and devices. Sync Framework features technologies and tools that enable roaming, data sharing, and taking data offline. By using Sync Framework, developers can build synchronization ecosystems that integrate any application with data from any store, by using any protocol over any network.
Today at Build, we announced the release of Visual Studio 2017 version 15.7 and the first preview of the next update, Visual Studio 2017 version 15.8 Preview 1.
In summary, the most important issues here are:
- The Aggregate’s main task is to protect invariants (business rules, the boundary of immediate consistency)
- In a multi-threaded environment, when multiple threads are running simultaneously on the same Aggregate, a business rule may be broken
- A way to solve concurrency conflicts is to use Pessimistic or Optimistic concurrency techniques
- Pessimistic Concurrency involves the use of a database transaction and a locking mechanism. In this way, requests are processed one after the other, so basically concurrency is lost and it can lead to deadlocks.
- Optimistic Concurrency technique is based on versioning database records and checking whether the previously loaded version has not been changed by another thread.
- Entity Framework Core supports Optimistic Concurrency. Pessimistic Concurrency is not supported
- The Aggregate must always be treated and versioned as a single unit
- Domain events are an indicator, that state was changed so Aggregate version should be changed as well
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();
Get Started Building Microservices with ASP.NET Core and Docker in Visual Studio Code

Database collations
The default collation for a database can now be specified in the EF model.
This will flow through to generated migrations to set the collation when the database is created.
For example:
modelBuilder.UseCollation("German_PhoneBook_CI_AS"); 
Today Microsoft announced the next version of Windows and a new Windows Store, and we’re excited to see how people take advantage of its new features. One thing that hasn’t changed is that Windows is still the best platform to design, build, test, and deploy Android apps.
