Data architecture is an area in which the optimal degree of isolation for a SaaS application can vary significantly depending on technical and business considerations. Experienced data architects are used to considering a broad spectrum of choices when designing an architecture to meet a specific set of challenges, and SaaS is certainly no exception. We shall examine three broad approaches, each of which lies at a different location in the continuum between isolation and sharing 

From LGPL to Polyform Noncommercial

From version 5, we have changed the license from LGPL to Polyform Noncommercial 1.0.0 - a license that permits noncommercial use only. In combination with the Polyform Noncommercial license we sell licenses for customers who use EPPlus in a commercial business. Since EPPlus has been around for a while, you might wonder why we have decided to do this change.  

With the release of .NET5 Preview 8, we have introduced a streamlined way for .NET developers to access the set of Windows Runtime (WinRT) APIs that are shipped as part of Windows.  

A Blazor wrapper for the browser API File System Access

The API makes it possible to read and write to your local file system from the browser both files and directories. 

Previous versions of ASP.NET included the Web API framework for creating web APIs. In ASP.NET 5, this functionality has been merged into the MVC 6 framework. Unifying the two frameworks makes it simpler to build apps that include both UI (HTML) and APIs, because now they share the same code base and pipeline. 

ES7 gives us a new kind of function, the async function. Inside of an async function, we have a new keyword, await, which we use to "wait for" a promise 

WhatsApp had 450 million monthly users and just 32 engineers when it was acquired. Imgur scaled to over 40 billion monthly image views with just seven engineers. Instagram had 30 million users and just 13 engineers when it was acquired for $1 billion dollars.
This is the new normal: fewer engineers and dollars to ship code to more users than ever before. The potential impact of the lone software engineer is soaring. How long before we have a billion-dollar acquisition offer for a one-engineer startup? How long before the role of an engineer, artisanally crafting custom solutions, vanishes altogether?

Starting with .NET Core 3.0 Preview 7, the .NET Core SDK installer will remove previous patch versions after a successful installation. This means that if you have 3.0 Preview 5 and Preview 7 on a machine then install Preview 7, only Preview 7 will remain once the process is complete.
