This tool will enable you to create data dictionary for your tables and export them to an Excel file.

WebWindow؛ جایگزین الکترون برای برنامه‌های NET Core.

My last post investigated ways to build a .NET Core desktop/console app with a web-rendered UI without bringing in the full weight of Electron. This seems to have interested a lot of people, so I decided to upgrade it to newer technologies and add cross-platform support.

The result is a little NuGet package called WebWindow that you can add to any .NET Core console app. It can open a native OS window (Windows/Mac/Linux) containing web-based UI, without your app having to bundle either Node or Chromium.

Marten 3.0 منتشر شد

Marten 3.0 is live on Nuget. It didn’t turn out to be a huge release, but we needed to accommodate the Npgsql 4.* dependency and I felt like that was a breaking change, so here we go.

انتخاب بهترین دیتابیس برای اپلیکیشن با توجه به انتظارات

There are a lot of things to consider when choosing your database. Choose wisely because you’ll be married to that database for a long time. One case study is Amazon Marketplace which started with Oracle and tried to migrate after developing their own database solutions. The migration took somewhere between 5 to 10 years, and they seem to be still partially using Oracle. Though if your company reaches Amazon scale, then you’re probably doing very well.

روش های مقایسه اشیاء با null

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.

کتاب رایگان UWP Succinctly
Modern Microsoft is much more than Windows, and to reach their full potential developers must be able to reach users on the many platforms they use. To facilitate this, Microsoft created Universal Windows Platform (UWP) to make development across multiple platforms simultaneously an achievable goal. In UWP Succinctly, the first part of a series, author Matteo Pagani guides readers towards developing their own UWP applications.
Table of Contents
  1. Introduction
  2. The Essential Concepts: Visual Studio, XAML, and C#

OpenCV 3.0 منتشر شد

With a great pleasure and great relief OpenCV team finally announces OpenCV 3.0 gold release, the most functional and the fastest OpenCV ever. And yet it’s very stable too – all the thousands of tests that we created during the project + many new tests pass successfully on Windows, Linux and Mac, x64 and ARM.
