This is an exciting time for AI. New advances in the field have the potential to make AI more helpful for billions of people over the coming years. Since introducing Gemini 1.0, we’ve been testing, refining, and enhancing its capabilities.

Gemini 1.5 delivers dramatically enhanced performance. It represents a step change in our approach, building upon research and engineering innovations across nearly every part of our foundation model development and infrastructure. This includes making Gemini 1.5 more efficient to train and serve, with a new Mixture-of-Experts (MoE) architecture.

In a recent conversation between the CEOs of Microsoft and OpenAI, it was revealed by Sam Altman that ChatGPT-5 is expected to receive significant updates to its speech, images, and eventually video capabilities.

On his “Unconfuse Me” podcast, Bill Gates, along with Altman, explored the future of artificial intelligence, including its improved reasoning ability and general reliability. “Multimodality will be important,” Altman said, hinting at a future where artificial intelligence (AI) can perform increasingly complex tasks and potentially reshape various sectors, including programming, healthcare, and education.

Anticipation is building for the next iteration of ChatGPT, known as GPT-5. This advanced large language model is seen as a crucial milestone on the path to achieving artificial general intelligence (AGI), enabling machines to mimic human thought processes.

URI stands for Uniform Resource Identifier. A URI is a string of characters that identifies a particular resource. Resources can be anything with an identity, such as a document, image, service, or concept. URIs are used to uniquely identify and locate resources on the internet or within a network.

The Task class is a key component of the Task Parallel Library, providing a framework for asynchronous programming. It represents a unit of work that can run concurrently with other tasks, offering efficient and scalable execution. Programmers use it to create, manage, and coordinate asynchronous operations, enhancing application responsiveness.

Namespace: System.Threading.Tasks

The Thread class allows programmers to create and manage multithreaded applications. It enables concurrent code execution, allowing tasks to run independently for improved performance. Developers can utilize methods like Start, Join, and Sleep to control thread execution, facilitating efficient parallel processing in .NET applications.

Namespace: System.Threading

In C#, Task.Delay and Thread.Sleep are both used to introduce delays or pauses in the execution of your code, but they have different use cases and implications.

In summary, use Task.Delay when working with asynchronous code and you want to avoid blocking the current thread. Use Thread.Sleep when you explicitly want to block the current thread, but be cautious about using it in scenarios where responsiveness is important, such as in GUI applications. In modern C# applications, with the widespread use of async/await, Task.Delay is often the more appropriate choice.

The Thread.Sleep Method Suspends the current thread for the specified amount of time.

  • Thread.Sleep is a synchronous method that blocks the current thread for the specified amount of time.
  • It's generally used in non-async scenarios or when dealing with multi-threading where you explicitly want to pause the execution of the current thread.
  • It can introduce responsiveness issues, especially in GUI applications, as it will freeze the UI during the sleep period.


void MyMethod()
    // Do something before the delay
    Thread.Sleep(1000); // Sleep for 1000 milliseconds (1 second)
    // Do something after the delay
.NET by Patrik
...see more

The Task.Delay Method creates a task that will complete after a time delay.

  • Task.Delay is generally preferred when working with asynchronous programming using async and await.
  • It returns a Task that represents a time delay.
  • It doesn't block the calling thread. Instead, it allows the thread to be released and continue with other work while waiting for the specified time to elapse.
  • It's more suitable for scenarios where you want to introduce a delay without blocking the execution of the current method or freezing the user interface in GUI applications.


async Task MyMethod()
    // Do something before the delay
    await Task.Delay(1000); // Delay for 1000 milliseconds (1 second)
    // Do something after the delay

.NET APIs include classes, interfaces, delegates, and value types that expedite and optimize the development process and provide access to system functionality.

.NET types use a dot syntax naming scheme that connotes a hierarchy. This technique groups related types into namespaces, which can be searched and referenced more easily. The first part of the full name—up to the rightmost dot—is the namespace name.

The System namespace is the root namespace for fundamental types in .NET. This namespace includes classes representing the base data types used by all applications.

.NET includes a set of data structures that are the workhorses of many .NET apps. These are mostly collections, but also include other types.

.NET includes a set of utility APIs that provide functionality for many important tasks.

There are many app models that can be used with .NET.

The Task asynchronous programming model (TAP) provides an abstraction over asynchronous code. You write code as a sequence of statements, just like always. You can read that code as though each statement completes before the next begins. The compiler performs many transformations because some of those statements may start work and return a Task representing the ongoing work.

In C#, you can replace multiple white spaces with a single white space using regular expressions. You can use the Regex class from the System.Text.RegularExpressions namespace to achieve this. Here's an example:

using System;
using System.Text.RegularExpressions;

class Program
    static void Main()
        string inputString = "This   is   a    sample    string   with   multiple   spaces.";

        // Use regular expression to replace multiple white spaces with a single white space
        string result = Regex.Replace(inputString, @"\s+", " ");

        Console.WriteLine("Original string: " + inputString);
        Console.WriteLine("Modified string: " + result);

In this example, the \s+ regular expression pattern matches one or more white spaces, and the Regex.Replace method replaces these occurrences with a single white space.

Make EF Core update only the updated properties by turning the disconnected scenario to connected.

public void SaveBook(Book book)
    // Here, 'book' is the book with the changed Title.
    using(var context = new TestContext())
        var dbBook = context.Books.Find(book.ID);

        // Copy book's property values to dbBook.


There may be good reasons to prefer the latter method above the former.

Instruct EF Core to create a migration named InitialCreate:

Add-Migration InitialCreate

EF Core will create a directory called Migrations in your project, and generate some files. It's a good idea to inspect what exactly EF Core generated - and possibly amend it - but we'll skip over that for now.

You can remove the latest migration with the following command:

You can list all existing migrations as follows:

Create a database and create your schema from the migration. This can be done via the following:


That's all there is to it - your application is ready to run on your new database, and you didn't need to write a single line of SQL. Note that this way of applying migrations is ideal for local development, but is less suitable for production environments - see the Applying Migrations page for more info.

OriginalString and AbsoluteUri have different behaviors.

AbsoluteUri does escaping

Uri uri = new Uri(" world");

// world

//  <--  different

AbsoluteUri doesn't support relative URIs

var uri = new Uri("/test.aspx?v=hello world", UriKind.Relative);

// /test.aspx?v=hello world

// InvalidOperationException: This operation is not supported for a relative URI.
