Data Connections

Create Similar Connection

A new option now exists in the data connection context-menu to duplicate a connection.

Preview

Entity Framework Compiled Models

Entity Framework takes time to initialize on first use. The larger the data model, the more time it needs. For large models (100s or 1000s of entities and relationships) script startup can be sped up using a compiled model. An option to use a compiled model for a data connection now exists in Connection: Properties > Scaffolding.

Note that using compiled models is not effective for smaller models, and comes with some limitations. It is recommended to only use this option if you need it.

Editor Styling

The editor has some pre-defined themes you can now pick from in Settings > Editor. These themes come from the monaco-themes project.

Example, the GitHub Dark theme:

You can also tweak the current editor theme using the themeCustomizations property in the Monaco options editor.

Example:

"themeCustomizations": {
    // General editor colors
    "colors": {
      "editor.background": "#282a36"
    },

    // Semantic highlighting token styles
    "rules": [
      {
        "token": "interface",
        "foreground": "50fa7b",
        "fontStyle": "underline"
      }
    ]
}

See IColors and ITokenThemeRule for the definition of the colors and rules properties respectively.

See wiki for more info.

App Styling

The new Settings > Styles was added as a way to define custom styles that apply to the whole application.

For example to increase the font size of output:

.dump-container {
    font-size: 1.25rem;
}

This feature also works great with the ability to specify CSS classes you want a dumped value to have, introduced in v0.7.0:

myObj.Dump(css: "important");

.important {
  background-color: salmon;
}

You can also override CSS variables on the built-in theme-netpad-dark and theme-netpad-light themes. Here's an example customizing the dark theme with the Dracula theme color palette:

.theme-netpad-dark {
    --drac-light: #343746;
    --drac-dark: #22222c;

    --text-color: #F8F8F2;
    --background-color: var(--drac-dark);
    --list-background: var(--drac-light);
    --form-control-background-color: #343746;
    --active-color: #dbb5fa;
    --script-toolbar-background: #242632;
    --pane-ribbon-background: var(--drac-light);
    --pane-background: var(--drac-dark);
    --pane-toolbar-background: var(--drac-dark);
    --dialog-background: var(--drac-dark);
    --tab-background: #333541;
    --tab-active-background: #242632;
    --tab-active-text-color: #fffff;
    --scrollbar-thumb-color: #777777;
    --splitter-color: #2b2d39;
}

NuGet

NetPad will recognize additional NuGet sources added to your Nuget.Config file (#119). Thank you @jsamse for that contribution.

There is no UI to manage NuGet sources in NetPad so far so you'll have to add them manually. More info

Media File Sizing

Media files will now be rendered in their original size, but you can also specify size using the DisplayWidth and DisplayHeight properties:

new Image("/path/to/img.png")
{
    DisplayWidth = "128px",
    DisplayHeight = "128px"
}.Dump();

Or using extension methods:

// Individually
Image.FromPath("/path/to/img.png")
  .WithDisplayWidth("100%");
  .WithDisplayHeight("400px");

// Together
Image.FromPath(imageFile).WithDisplaySize("100%", "400px");

See the wiki for more info.
