Visual Studio’s project templates enable you, the developer, to create multiple similar projects more efficiently by defining a common set of starter files. The project templates can be fully customized to meet the needs of a development team, or a group, and can be published to the Visual Studio Marketplace for others to download and use too! Once published, developers can install and access the template through Visual Studio’s New Project Dialog.

The newly designed New Project Dialog for Visual Studio 2019 was built to help developers get to their code faster. Using a search and filter focused experience, we are aiming to provide better discoverability for specific templates to start your application development

As more organizations are delivering innovation faster by moving their businesses to the cloud, increased security is critically important for every industry. Azure has built-in security controls across data, applications, compute, networking, identity, threat protection, and security management so you can customize protection and integrate partner solutions. 

We keep investing in security and we are excited to share exciting updates this week at Hannover Messe 2019. We are excited to announce that Dedicated Hardware Security Module Service (HMS) in UK, Canada, and Australia, Azure disk encryption support for Virtual Machine Scale Sets (VMSS) are generally available. Also Advanced Threat Protection for Azure Storage, the Regulatory Compliance Dashboard, and support for virtual machine sets are now generally available as part of Azure Security Center.

Git is a popular version control system. In Git, an atomic change of one or several files is called a commit, and several consecutive commits are combined into a branch. Branches are used to implement new ideas (features).

It happens that the idea is a dead end and the developer has turned the wrong way, so he needs to roll back to the original version. He should forget about the new branch, switch to the main dev or master branch and continue working. In this case, the "scion" will hang forever, as well as the desire to remove it. But how to remove the part of the history? This branch shows the efforts of the hard-working programmer, even if in vain. So it will be easier to report to the boss, because an unsuccessful result is also a result!

I hasten to rejoice that Git developers are going to introduce a new command to close such "homeless" branches in the third version. The current version is 2.21.0.

How to use this command, what benefits does it give and what do IT companies think? The article answers these and other questions.

We are now publishing .NET Core container images to Microsoft Container Registry (MCR). We have also made other changes to the images we publish, described in this post.

Important: You will need to change FROM statements in Dockerfile files and docker pull commands as a result of these changes. 3.0 references need to be changed now. Most 1.x and 2.x usages can be changed over time. The new tag scheme is decribed in this post and are provided at the microsoft-dotnet-core repo, our new home on Docker Hub.

Summary of changes:

• .NET Core images are now published to Microsoft Container Registry.
• Updates will continue to be published to Docker Hub, for .NET Core 1.x and 2.x.
• .NET Core 3.0 will only be published to MCR.
• Nano Server 2016 images are no longer supported or published.

It's 2019! Everybody thinks they know code splitting. So - let's double check!

What does code splitting stand for?

In short – code splitting is just about not loading a whole thing. Then you are reading this page you don't have to load a whole site. When you are selecting a single row from a database – you don't have to take all.
Obvious? Code splitting is also quite obvious, just not about your data, but your code.

Complex systems often appear chaotic or incomprehensible, yet closer examination reveals that such complexity can frequently be reduced to a simple underlying mechanism. By systematically removing layers of emergent behavior, one can uncover a fundamental rule or equation from which the entire system originates.

For years, we’ve studied Oracle to make PostgreSQL a more migration-friendly option. We introduced tools similar to SQL profile and SQL plan baseline as AQO and sr_plan extensions. In some cases, PostgreSQL even outperforms Oracle, especially in automatic re-optimization.

Migrations from Oracle to PostgreSQL are usually smooth performance-wise, and we’ve even developed session variable extensions to make the transition easier. While many enterprise-only features exist, PostgreSQL often integrates popular solutions directly into the core.
