# Execute the following cell.

You'll notice a counter that appears and starts incrementing.  After a second or two, stop the cell.  Your output should look similar to:

```
5
Error: Comamnd cancelled
```

#!csharp

using System.Threading.Tasks;
using Microsoft.DotNet.Interactive;

var output = string.Empty.Display("text/plain");
var counter = 1;
while (!KernelInvocationContext.Current.CancellationToken.IsCancellationRequested)
{
    await Task.Delay(500, KernelInvocationContext.Current.CancellationToken);
    output.Update($"{counter++}");
}

#!markdown

# Execute the next two cells.

#!csharp

var x = 123;

#!html

<div id="output"></div>

#!markdown

# Execute the next cell.  After execution, the output immediately above this should read:

```
The value is 123.
```

#!javascript

const x = await interactive.csharp.getVariable("x");
document.getElementById("output").innerText = `The value is ${x}.`;

#!markdown

# Execute the next cell, the output should be displayed as JSON like so:

``` json
{"Name":"Developer","Salary":42}
```

#!csharp

display(new { Name = "Developer", Salary = 42 }, "application/json");

#!markdown

# Execute the next cell and verify the following error appears:

```
Error: input.fsx (1,11)-(1,12) parse error Unexpected token '+' or incomplete expression
```

#!fsharp

let x = 1 +

# Check this manual scenario:

1. `Ctrl+Shift+P` => ".NET Interactive: Create new blank notebook"
2. Select "Create as .dib"
3. Select "F#"
4. You should have a new empty notebook named something like "Untitled-1.dib" with a single cell of type "F# (Interactive)".
5. Set the cell contents to `1+1` and execute.
6. Verify output of `2`.
7. Save to disk.
8. Open that file in notepad.
9. The contents should look like this:

   ```
   #!fsharp

   1+1
   ```

#!markdown

# Execute the above scenario again with the following changes:

2. Select "Create as .ipynb"
4. File should be named something like "Untitled-1.ipynb".

(new steps)

9. The contents should look like this:

``` json
{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": null,
   "metadata": {
    "dotnet_interactive": {
     "language": "fsharp"
    }
   },
   "outputs": [
    {
     "data": {
      "text/html": [
       "<div class=\"dni-plaintext\">2</div>"
      ]
     },
     "output_type": "unknown"
    }
   ],
   "source": [
    "1+1"
   ]

  }
 },
 "nbformat": 4,

}
```

# Open the two previously saved notebooks via the following:

1. `Ctrl+Shift+P` => ".NET Interactive: Open notebook"
2. Select the "Untitled-1.dib"/"Untitled-1.ipynb" from before.
3. Verify that it contains a single F# cell with the contents "1+1" and that it can execute.
