The volatile keyword in C# is used to inform the JIT compiler that the value of the variable should never be cached because it might be changed by the operating system, the hardware, or a concurrently executing thread.
Issues Fixed in this Release
Xamarin app throws Cannot access a disposed object. Object name: 'MobileAuthenticatedStream'error.
Xamarin.Android app throws ClassNotFoundException when deriving from Application class.
Upgrading may cause previously installed Windows and Android SDKs to be uninstalled.
Bumped JDK 8 to the latest version to avoid download failures from Oracle website.
A Microsoft exec has warned that Internet Explorer is a ‘compatibility solution’ and should only be used selectively. Preaching to the choir here, and this is, we suspect, the very end of IE's long story for us.
The cost of JavaScript in 2019
Based on the above observations, we can conclude that React will be the best framework to learn in 2021, followed by Vue. But there is a high chance of Angular defending second place since it has been there for a longer period of time than Vue, and surely 2021 is not the end of that. So if you are an Angular developer, I suggest you learn React in the upcoming days.
This is a GitBook version of the '97 Things Every Programmer Should Know' project.
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();
Well, the speculation is now over and Blazor WebAssembly is expected in May 2020! Which should put it right around Build time next year.
The 6.0.0 release of Angular is here! This is a major release focused less on the underlying framework, and more on the toolchain and on making it easier to move quickly with Angular in the future.
