We’re proud to announce the release of PowerShell 7.1, the latest major update to PowerShell 7. This release includes a number of improvements and fixes that build on top of the PowerShell 7.0 release in March and the recent GA release of .NET 5.  

- Added `Select *` plugin.
- Added `Duplicate Commands Per Context` plugin.
- Updated ByMethods plugin to show stack traces of commands.
- Added ability of closing/hiding different tabs.
- Added assembly info to methods info view.
- Updated the NuGet Packages
PM> Update-Package DNTProfiler.EntityFramework.Core
Or
PM> Update-Package DNTProfiler.NHibernate.Core 

We announced support for HTTP/3, the successor to HTTP/2 during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Collaborating on standards is a big part of that, and we're very fortunate to do that here

How you shouldn’t implement base classes

public class Entity<T>
{

  public T Id { get; protected set; }

}

Motivation for such code it pretty clear: you have a base class that can be reused across multiple projects. For instance, if there is a web application with GUID Id columns in the database and a desktop app with integer Ids, it might seem a good idea to have the same class for both of them. In fact, this approach introduces accidental complexity because of premature generalization. 

There is no need in using a single base entity class for more than one project or bounded context. Each domain has its unique path, so let it grow independently. Just copy and paste the base entity class to a new project and specify the exact type that will be used for the Id property. 

2015 has been a monumental year for Cloud Technology and SaaS in particular. So much has happened, and so much has been discussed, and capturing the very best was not an easy task. Still, I managed to gather what I believe are the top 20 of 2015, from mistakes every SaaS vendor needs to avoid, to insights about the future of Microsoft.  

bool totalSuccess = First() & Second();
If you want both operations to happen regardless of whether the first succeeded then using && would be wrong. (And similarly if you want to know if either succeeded, you’d use | instead of ||.)
