- Top level programs/statements
- Init only & new()
 

من از کدهای ایمیل شما استفاده کردم در لوکال هاست به درستی کار میکند و ایمیل ارسال میشود ولی در هاست ایمیل ارسال نمیشود و(البته پیغام ارسال شدن کد رو نیز میدهد) من از جیمیل برای ارسال ایمیل استفاده کردم و گوگل ایمیل زیر رو برام ارسال کرد

به نظرتون چرا در هاست از ارسال ایمیل جلوگیری میکنه؟

آیا باید در هاست تنظیمات دیگری رو نیز اعمال کنیم؟

با تشکر

Kent’s rules, from Extreme Programming Explained are:

• Runs all the tests
• Has no duplicated logic. Be wary of hidden duplication like parallel class hierarchies
• States every intention important to the programmer
• Has the fewest possible classes and methods

In my experience, these don’t quite serve the needs of software design. My four rules might be that a well-designed system:

• is well-covered by passing tests.
• has no abstractions not directly needed by the program.
• has unambiguous behavior.
• requires the fewest number of concepts.

From the team that brought you Windows Terminal, Windows Subsystem for Linux, PowerToys and Windows Package Manager (WinGet), we are excited to introduce Dev Home, a new open-source experience in Windows created just for developers.  

.NET 8 Preview 3 is now available. It includes changes to build paths, workloads, Microsoft.Extensions, and containers. It also includes performance improvements in the JIT, for Arm64, and dynamic PGO. If you missed the March preview, you may want to read the Preview 2 post. 

Check	Code	Description
Is Null	if(variable is null) return true;	This syntax supports static analysis such that later code will know whether variable is null or not.  Doesn’t produce a warning even when comparing against a non-nullable value type making the code to check pointless.  Requires C# 7.0 because it leverages type pattern matching.
Is Not Null	if(variable is { }) return false	This syntax supports static analysis such that later code will know whether variable is null or not.  Requires C# 8.0 since this is the method for checking for not null using property pattern matching.
Is Not Null	if(variable is object) return false	Triggers a warning when comparing a non-nullable value type which could never be null  This syntax works with C# 8.0’s static analysis so later code will know that variable has been checked for null. Checks if the value not null by testing whether it is of type object.  (Relies on the fact that null values are not of type object.)
Is Null	if(variable == null) return true	The only way to check for null prior to C# 7.0.  However, because the equality operator can be overridden, this has the (remote) possibility of failing or introducing a performance issue.
Is Not Null	if(variable != null) return false	The only way to check for not null prior to C# 7.0.  Since the not-equal operator can be overridden, this has the (remote) possibility of failing or introducing a performance issue.

Main course contains 2 parts which cover JavaScript as a programming language and working with a browser. There are also additional series of thematic articles. 

Creator of Python, Guido van Rossum, has joined Microsoft as a Distinguished Engineer in the Developer Division. His stated aim is to make Python better. We can't wait to find out what that results in.
