Latest Beta


  • When dumping to data grids, you can now right-click the grid and elect to order the columns alphabetically.
  • You can now disable My Extensions on a per-query basis, to avoid a conflict with extension methods defined in the query. Go to the Query Properties dialog (F4) and click the Advanced tab.
  • Databases now appear in alphabetical order when connecting to Azure servers.
  • There's a new property in LINQPad's Util class called SelectedOutputPanelIndex. You can set this to change the active output panel (Results, SQL, Custom, etc.). There's also a new property called IsDarkThemeEnabled to help you correctly render HTML and controls when customizing output.
  • When specifying a custom .config file for a query, you can now point to a file that uses customSource attributes to merge items from other config files. This works even if you reference NuGet packages that require binding redirects, and LINQPad has to create a new .config file to merge the binding redirects.
  • LINQPad's "power-tick" feature now works for VB queries, too.
  • Autocompletion now recognizes attributes when prompting for constructor arguments.
  • With F# queries, the DEBUG symbol is now automatically defined.
  • The 'power-tick' is now supported with VB queries.


  • An error when displaying certain documentation tags in F# queries has been fixed.
  • When running command-line queries, NuGet packages referenced in My Extensions will now automatically download.
  • You can now dump ImmutableArray.Default without error.
  • Calling Console.Write with an empty string no longer emits a new line.
  • Multi-monitor setups in Windows 10 should now work correctly with monitors that have differing DPIs.
  • The query runtime now returns Framework 4.6 when queried, to ensure full compatibility with new features.
  • The latest release of BenchmarkDotNet now works correctly with LINQPad.
  • LINQPad now applies the necessary binding redirects to make SQL Geography/Geometry types work with later versions of Microsoft.SqlServer.Types.dll.
  • Code snippets with keyboard shortcuts that contain underscores now work correctly.
  • Allowing LINQPad to access internal types of other assemblies no longer upsets F# queries.
  • Focus within autocompletion listings now respects multi-part words and camel humps.

LINQPad 5 vs LINQPad 4

LINQPad 5 targets .NET Framework 4.6 and includes the following major new features:

  • Full support for C# 7 and VB 15.
  • Background code-checking - both parsing and binding errors show with red squigglies. Resolved symbols display in turquoise, and unresolved symbols in red. Compilation is quicker, because most of the work is done in advance.
  • (Pro/Premium Editions) Automatic code formatting, 'Rename Symbol', 'Jump to Definition', and 'Find References'.
  • (Pro/Premium Editions) Autocompletion for VB, including member listings, parameter info, quick info, background compilation, smart-tags, and auto-formatting.
  • (Pro/Premium Editions) Autocompletion for F#, including member listings, parameter info and quick info.
  • Built-in F# compiler (so fsc.exe is not required) with full F# autocompletion.
  • Built-in Roslyn Syntax Tree Visualizer. The syntax tree for your query appears automatically as an output tab, and you can invoke it programmatically with .DumpSyntaxTree() or .DumpSyntaxNode().
  • Authenticated feed support within the NuGet package manager.

If you own a Pro or Premium edition of LINQPad 4, LINQPad 5 is a paid upgrade.
