.Net Core is a lightweight and cross-platform version of the DotNet framework and the awesome thing is Developers required the same expertise to work with Asp.Net Core as .Net Framework.

It can be difficult  to write unit tests for code that accesses the file system. 

Some key areas of focus uncovered by this investigation were:

• Being mindful of memory allocations to minimize GC pause times

• Keeping long-running calls non-blocking/asynchronous

• Minimizing calls to external resources (such as other web services or the database) with caching and grouping of requests 

Why use View Components and not Partial Views? The biggest reason is that when inserting a Partial View into a Razor page, all the ViewData associated with the calling View is automatically associated with the Partial View. This means that a Partial View may behave very differently on one Razor page than on another. With View Components, you control what gets shared to your View Components. 

Angular 6 is out! The most outstanding changes are in its CLI and how services get injected. If you are looking to write your very first Angular 6 app—or Angular/Firebase app—in this tutorial, we’ll go over the basic steps of initial setup and create a small diary app. 

I was pleasantly surprised by how easy it was to setup and install ASP.NET Core 2.1 on Linux. I did it for the first time in 15 minutes with no previous experience with .NET Core on Linux. I did it the second time, in production, in 5 minutes by following these instructions.

In this article, I show you how to install the .NET Core runtime on CentOS, how to get a sample ASP.NET Core project running on Kestrel as a service for reliability, and how to configure both the code and the firewall to enable remote access. Finally, I discuss what I would do differently for actual production usage. 

DECLARE @char CHAR = ''
DECLARE @charI INT = 0
DECLARE @password VARCHAR(100) = ''
DECLARE @len INT = 12 -- Length of Password
WHILE @len > 0
BEGIN
SET @charI = ROUND(RAND()*100,0)
SET @char = CHAR(@charI)

IF @charI > 48 AND @charI < 122
BEGIN
SET @password += @char
SET @len = @len - 1
END
END
SELECT @password [PassWord]  

C# 7 introduced pattern matching with the extension of the switch statement and the is operator offering the const pattern, the type pattern, and the var pattern. With C# 8 an extension of pattern matching is planned, including the property pattern, the recursive pattern, and a new switch – the switch expression.
