# F# (.NET Core Latest)
2+
3+
## Summary
4+
5+
*Develop F# and .NET Core (latest) based applications. Includes all needed SDKs, extensions, and dependencies.*
6+
7+
| Metadata | Value |
8+
|----------|-------|
9+
| *Contributors* | The VS Code Team, F# team |
10+
| *Definition type* | Dockerfile |
11+
| *Languages, platforms* | .NET Core, F# |
12+
13+
## Using this definition with an existing folder
14+
15+
Note that only the integrated terminal is supported by the Remote - Containers extension. You may need to modify `launch.json` configurations to include the following value if an external console is used.
16+
17+
```json
18+
"console": "integratedTerminal"
19+
```
20+
21+
Beyond that, just follow these steps to use the definition:
22+
23+
1. If this is your first time using a development container, please follow the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started) to set up your machine.
24+
25+
2. To use VS Code's copy of this definition:
26+
1. Start VS Code and open your project folder.
27+
2. Press <kbd>F1</kbd> select and **Remote-Containers: Add Development Container Configuration Files...** from the command palette.
28+
3. Select the F# (.NET Core Latest) definition.
29+
30+
3. To use latest-and-greatest copy of this definition from the repository:
31+
1. Clone this repository.
32+
2. Copy the contents of `containers/dotnetcore-latest-fsharp/.devcontainer` to the root of your project folder.
33+
3. Start VS Code and open your project folder.
34+
35+
4. After following step 2 or 3, the contents of the `.devcontainer` folder in your project can be adapted to meet your needs.
36+
37+
5. Finally, press <kbd>F1</kbd> and run **Remote-Containers: Reopen Folder in Container** to start using the definition.
38+
39+
## Testing the definition
40+
41+
This definition includes some test code that will help you verify it is working as expected on your system. Follow these steps:
42+
43+
1. If this is your first time using a development container, please follow the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started) to set up your machine.
44+
2. Clone this repository.
45+
3. Start VS Code, press <kbd>F1</kbd>, and select **Remote-Containers: Open Folder in Container...**
46+
4. Select the `containers/dotnetcore-latest-fsharp` folder.
47+
5. When prompted click "Restore" in the notification to restore packages.
48+
6. After the folder has opened in the container, press <kbd>F5</kbd> to start the project.
49+
7. You should see "Hello Remote World from the F# Container!" in a terminal window after the program executes.
50+
8. From here, you can add breakpoints or edit the contents of the `test-project` folder to do further testing.
