I think most developers start this way (code behind instead of XAML). XAML isn't immediately intuitive, but once you cross the boundary (of understanding) XAML tends to be a simpler approach. And, frankly, I tend to think that simplicity is always the better choice
the SQL Server 2014 Express release includes the full version of SQL Server 2014 Management Studio.
SQL is unusual is that data is not passively stored. Instead you use declarative SQL to specify the rules that underlie the data and its integrity. When used properly, constraints can avoid having to provide a lot of logic elsewhere. CHECK() and DEFAULT can do a lot to ensure that your data is correct

Now, it seems like the rumor is going to be real. Yesterday there was a Windows 11 Build leaked online from a Chinese portal, and we got to know more about that build. Here's a quick look at Windows 11 that is expected to be released later this year.
f you are a developer and building apps or games for Windows 10, targetting Universal Windows Platform (aka. UWP), you might want to show toast notifications to the user of your app/game. You might also want to provide some additional content like textbox, button etc. to get specific inputs.
// The getDate() function returns a nested function which refers the 'date' variable defined
// by outer function getDate()
function getDate() {
var date = new Date(); // This variable stays around even after function returns
// nested function
return function () {
return date.getMilliseconds();
}
}
// Once getDate() is executed the variable date should be out of scope and it is, but since // the inner function // referenes date, this value is available to the inner function. var dt = getDate(); alert(dt()); alert(dt());
function myNonClosure() {
var date = new Date();
return date.getMilliseconds();
}
var MyDate = function () {
var date = new Date();
var getMilliSeconds = function () {
return date.getMilliseconds();
}
}
var dt = new MyDate();
alert(dt.getMilliSeconds()); // This will throw error as getMilliSeconds is not accessible.
// This is closure

var date = new Date(); // variable stays around even after function returns
var getMilliSeconds = function () {
return date.getMilliseconds();
};
return {
getMs : getMilliSeconds

There are two things you should keep in mind:
1. Don't wrap asynchronous tasks in another call to Task.Run().
2. Don't use asynchronous wrappers over synchronous calls.
