What are digital signatures and what do they tell us, what information do they hold? All this and more are explained in this article.

.NET 7 minimal API from scratch | FULL COURSE | clean architecture, repository pattern, CQRS MediatR

In this course I want to provide you a project structure and code organization to get you started with real .NET 7 minimal API projects. It's a full course on this topic where I start from creating and explaining the project structure, setting up different layers using EF Core, repository pattern, CQRS and MediatR. The biggest part of the video is however around the .NET 7 minimal API, taking you from the initial setup, explaining route handlers, implementing all CRUD operations and so on. Last but not least, this course walks you through the process of refactoring the .NET 7 minimal API so that it becomes readable, maintainable and scalable. At the end, you'll have a full project structure organized according to modern architectural patterns that you can take as a template for your own projects.

Build 2021 is almost here, and Microsoft has published its catalog for sessions that will be ongoing throughout the event. We've rounded up some of the most interesting ones that we think you won't want to miss. Let's dive in! 

IKVM is an implementation of Java for the Microsoft .NET platform. It can be used to quickly and easily:

• Execute compiled Java code (bytecode) on .NET Framework or .NET Core
• Convert bytecode to a .NET assembly to directly access its API in a .NET project 

Today we announced the general availability of SQL Server 2016, the world’s fastest and most price-performant database for HTAP (Hybrid Transactional and Analytical Processing) with updateable, in-memory columnstores and advanced analytics through deep integration with R Services. Software applications can now deploy sophisticated analytics and machine learning models in the database resulting in 100x or more speedup in time to insight, compared to deployments of such models outside of the database. 

- 4 Microsoft SQL Servers (new hardware for 2 of them)
- 11 IIS Web Servers (new hardware)
- 2 Redis Servers (new hardware)
- 3 Tag Engine servers (new hardware for 2 of the 3)
- 3 Elasticsearch servers (same)
- 4 HAProxy Load Balancers (added 2 to support CloudFlare)
- 2 Networks (each a Nexus 5596 Core + 2232TM Fabric Extenders, upgraded to 10Gbps everywhere)
- 2 Fortinet 800C Firewalls (replaced Cisco 5525-X ASAs)
- 2 Cisco ASR-1001 Routers (replaced Cisco 3945 Routers)
- 2 Cisco ASR-1001-x Routers (new!)
