ASP.NET Core is a completely new web framework for building modern cloud-based web applications. In this presentation learn all about ASP.NET Core and including the latest features and innovations in MVC. You’ll see how you can build applications that run cross-platform on Windows, Mac and Linux via .NET Core. You’ll also see how ASP.NET Core MVC gives you a unified web programming model for building both web UI and web APIs.
 

CircuitBreaker.Net is an implementation of the Circuit Breaker pattern for .NET. This pattern can improve the stability and resiliency of your application, especially in SOAP, microservices and distributed environments.  

How do I create a new serverless project? How do I run and debug code locally? How do I install dependencies? How do I connect to third-party services? Where can I save connection strings? How do I customize the URL path? How can I deploy to the cloud? 

Fluent interfaces are software API's designed to be readable and to flow. They are like a miniature domain-specific language, code structured for one specific purpose. 

Jint is a Javascript interpreter for .NET which can run on any modern .NET platform as it supports .NET Standard 2.0 and .NET 4.6.1 targets (and up). Because Jint neither generates any .NET bytecode nor uses the DLR it runs relatively small scripts really fast. 

Modern software development practices value quick and continuous updates, following processes that minimize the impact of software failures. As important as identifying bugs early, finding out if changes are improving business value are equally important. These practices can only work when a monitoring solution is in place. This article explores options for adding observability to .NET Core apps. They have been collected based on interactions with customers using .NET Core in different environments. We will be looking into OpenTelemetry and Application Insights SDKs to add observability to a sample distributed application. 

In development world, you may get a requirement from your client, they wants a weekly, quarterly and yearly charts. You always think, how can I make charts with use of angularjs.  So today, in this article, we are going to learn

• how to create charts in angularjs using webapi
•  higcharts.js

In this example, our requirement is, we have dropdownlist of student names. if user select any student, it will show selected students marks in the form of charts. 

Security Advisory Notices

CVE-2019-1077 Visual Studio Extension Auto Update Vulnerability

An elevation of privilege vulnerability exists when the Visual Studio Extension auto-update process improperly performs certain file operations. An attacker who successfully exploited this vulnerability could delete files in arbitrary locations. To exploit this vulnerability, an attacker would require unprivileged access to a vulnerable system. The security update addresses the vulnerability by securing locations the Visual Studio Extension auto-update performs file operations in.

CVE-2019-1075 ASP.NET Core Spoofing Vulnerability

A spoofing vulnerability exists in ASP.NET Core that could lead to an open redirect. An attacker who successfully exploited the vulnerability could redirect a targeted user to a malicious website. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL and convince the user to click the link.

The security update addresses the vulnerability by correcting how ASP.NET Core parses URLs. Details can be found in the .NET Core release notes.

CVE-2019-1113 WorkflowDesigner XOML deserialization allows code execution

A XOML file referencing certain types could cause random code to be executed when the XOML file is opened in Visual Studio. There is now a restriction on what types are allowed to be used in XOML files. If a XOML file containing one of the newly unauthorized types is opened, a message is displayed explaining that the type is unauthorized.

For further information, please refer to https://support.microsoft.com/en-us/help/4512190/remote-code-execution-vulnerability-if-types-are-specified-in-xoml.

The previews of EF Core 5.0 require .NET Standard 2.1. This means:

• EF Core 5.0 runs on .NET Core 3.1; it does not require .NET 5.
  • This may change in future previews depending on how the plan for .NET 5 evolves.
• EF Core 5.0 runs on other platforms that support .NET Standard 2.1.
• EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework.
