From the apparent dismissal of Java evangelists to an email alleging a shrugged-shoulders attitude about Java, Oracle’s commitment to the platform has come into question.

These are the customer-reported issues addressed in this version:

Visual Studio crashes when you open a solution with a test project.
Visual Studio Freezes in Debug with Chrome.
Failure to install HelpViewer.
UI delay while typing R code.
C# 7.0 Regression in Tuples.
Xamarin - Dynamic Type Platform not supported exception.
Xamarin – Dynamic object is not supported.

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.

fn main() {
    println!("The sum of 2 and 3 is {}", sum(2, 3));
}

fn sum(a: i32, b: i32) -> i32 {
    a + b
}

fn function_name(parameter1: type1, parameter2: type2) -> return_type {
    // بدنه تابع
    // استفاده از مقادیر یارگشتی در صورت لزوم
}

fn greet(name: &str, age: i32) {
    println!("Hello, {}! You are {} years old.", name, age);
}

fn square(x: i32) -> i32 {
    return x * x;
}

fn square(x: i32) -> i32 {
    x * x
}

fn swap(a: i32, b: i32) -> (i32, i32) {
    (b, a)
}

let (b, a) = swap(1, 2);
println!("a is {} and b is {}", a, b);

let tuple = swap(1, 2);
println!("a is {} and b is {}", tuple.1, tuple.0);

Based on the above observations, we can conclude that React will be the best framework to learn in 2021, followed by Vue. But there is a high chance of Angular defending second place since it has been there for a longer period of time than Vue, and surely 2021 is not the end of that. So if you are an Angular developer, I suggest you learn React in the upcoming days.
