Copilot data is severely outdated? It says its data is up until September 2021

[datvm]

• VS Code Version: 1.86.0 (Universal)
• OS Version: 14.3 (23D56)
• Logs: See Chat log below.

Steps to Reproduce:

1. Ask about making Mac apps with MAUI -> AI gave info on .NET 6 which is like years ago.
2. Told it it's outdated -> AI proceeds to give info on .NET 6 RC1 which is even older.
3. Ask it about .NET 8 -> AI says it has no knowledge of .NET 8 (which is released half a year ago already) and that its knowledge is only up until Sep 2021.

datvm: I want to make Mac apps with MAUI

GitHub Copilot: That's great! .NET Multi-platform App UI (MAUI) is a framework for building native device applications spanning mobile, tablet, and desktop.

Here's a step-by-step guide to get you started:

1. **Install .NET 6 Preview**: MAUI is built with .NET 6, which is currently in preview. You can download it from the .NET website.

2. **Install MAUI**: Once you have .NET 6 installed, you can install MAUI by running the following command in your terminal:

```bash
dotnet new -i Microsoft.Maui.Templates
```

4. **Create a new MAUI App**: You can create a new MAUI app by running the following command in your terminal:

```bash
dotnet new maui -n MyApp
```

5. **Open the project in Visual Studio Code**: Navigate to the project directory and open it in VS Code:

```bash
cd MyApp
code .
```

6. **Run the App**: You can run the app using the .NET CLI. Make sure you have the necessary workloads installed for Mac development.

```bash
dotnet build
dotnet run
```

Remember, you'll need to have macOS Catalina 10.15.4 or above and Xcode 12.5 or above to build for Mac Catalyst.

Please note that as of now, MAUI is in preview and not all features may be available or stable.

datvm: this info is pretty outdated

GitHub Copilot: I apologize for the outdated information. As of .NET 6 RC1, the process to create a .NET MAUI app has changed. Here are the updated steps:

1. **Install .NET 6 RC1 or later**: You can download it from the .NET website.

2. **Install MAUI Check Tool**: This tool will ensure you have everything you need to create and build a MAUI app. Install it using the following command:

```bash
dotnet tool install -g Redth.Net.Maui.Check
```

3. **Run MAUI Check**: This will install all the necessary dependencies for you:

```bash
maui-check
```

4. **Create a new MAUI App**: You can create a new MAUI app by running the following command in your terminal:

```bash
dotnet new maui -n MyApp
```

5. **Open the project in Visual Studio 2022**: Currently, .NET MAUI development is supported in Visual Studio 2022. Open the project in Visual Studio 2022 and select the `MyApp.MacCatalyst` project as the startup project to run the app on Mac.

Please note that .NET MAUI is still in preview and not all features may be available or stable.

datvm: what about .NET 8?

GitHub Copilot: As of my current knowledge, .NET 8 has not been released or announced yet. The latest stable version of .NET is .NET 5, and .NET 6 is currently in release candidate stage. .NET 7 is expected to be the next version after .NET 6, following the yearly release cycle of .NET. 

For .NET MAUI, it is being developed with .NET 6. Therefore, to work with .NET MAUI, you should use .NET 6. 

Please check the official .NET website or the .NET GitHub page for the most up-to-date information.

datvm: what is the date of your knowledge?

GitHub Copilot: As an AI, I don't have real-time capabilities and my knowledge is based on the data I was trained on, which includes information up until September 2021. For the most recent updates or changes, please refer to the official documentation or resources.

datvm: that's not very useful

GitHub Copilot: I apologize if my previous responses didn't meet your expectations. As an AI, I strive to provide accurate and helpful information based on the data I was trained on. For real-time updates or changes, especially in fast-moving fields like software development, official documentation, forums, or direct communications with the software providers often provide the most accurate information. If you have more questions or need assistance with software development, feel free to ask.

Or simply asks it outright to make a .NET 8 app:

datvm: I want to make Mac apps with .NET 8

GitHub Copilot: .NET 8 is not yet released or available for use as of the time of this conversation. The latest stable version of .NET is .NET 6.0. However, you can develop Mac apps using .NET 6.0 with the help of Xamarin.Mac or MAUI (Multi-platform App UI), a cross-platform framework for building native UIs.

Here's a basic step-by-step guide to get you started with a new MAUI project:

1. Install the .NET 6.0 SDK.
2. Install the latest version of Visual Studio.
3. Create a new MAUI project.

```bash
dotnet new maui -n MyMauiApp
```

4. Navigate to the project directory.

```bash
cd MyMauiApp
```

5. Run the project.

```bash
dotnet build
dotnet run
```

This will create a new MAUI project that you can use to build Mac apps. You can design your UI using XAML and write your business logic in C#. The same codebase can be used to create apps for other platforms as well, such as Android, iOS, and Windows.

Remember, you'll need a Mac to compile and run your app for macOS.

The chat is currently powered by the GPT 4 model which has a knowledge cutoff in 2021. GPT 4 Turbo has a more recent knowledge cutoff

The link to the "duplicate" issue is just a link to the Issues page. Where is the duplicate issue, so I can track its progress? Do I need to create a new one? Just found out that Copilot data is so old that it only knows about .Net 6 preview and has no knowledge of .Net 8. When will the model be updated, or is Github Copilot effectively a dead product?

Sorry about that.
