LINQPad's autocompletion includes everything that you depend on:

• Completion and filtered member lists
• Parameter listing
• Quick info
• Code outlining
• Smart tags for importing namespaces (C#/VB)
• Code formatting (C#/VB)

Autocompletion works not only with LINQ queries, but the entire C#/F#/VB language.

LINQPad’s unique Power-Tick lets you select multiple properties, when creating anonymous types in C# or VB, without closing the popup. This is a massive time-saver.

When you enter an unresolved type or extension method, LINQPad offers a smart tag to import the namespace. And you don’t have to get the casing correct!

Access your favorite Visual Studio C#/VB code snippets, plus a dozen unique high-productivity LINQ snippets — as well as any custom snippets that you define.

Custom snippets can also include namespace imports, assembly references and NuGet package references. So you can set up an entire environment with just a few keypresses.

Use code fixes such as override method and implement interface/abstract class to boost your productivity.

LINQPad's integrated NuGet Package Manager puts the entire NuGet ecosystem at your fingertips.

LINQPad's local package cache ensures that you don't have to download a package again to use it in another query. You can even save package references to a code snippet, to recall them in a few keystrokes.

For your security, LINQPad checks packages for published vulnerabilities in the background and warns you when a potential issue is detected.

Open database tables for editing, and save changes back to the database. This feature works with SQL Server/Azure, SQLite, MySQL, Postgres and Oracle. The Premium edition also includes the ability to write cross-database queries — just control+drag additional databases from the Schema Explorer onto your query!

The Premium edition includes an integrated lightweight debugger. Single-step through your scripts, set breakpoints, and examine local variables! The debugger works with C#, VB and F# and can debug multi-threaded and asynchronous code.

LINQPad's debugger is unique in being fully asynchronous, so it never freezes under any conditions.

Best of all, the Premium edition includes advanced AI integration that works with your ChatGPT or Azure OpenAI account (so you don't need to pay a monthly subscription).

Not only does LINQPad give you AI completion, but an interactive AI chat window with 20 inbuilt prompts to examine and improve your code. There's even an Open Conversation prompt, for chats unrelated to LINQPad or programming. And if that isn't enough, you can write your own templates, with customized user and system prompts.

Because each conversation is fully rewritable (including the system prompt) you can use LINQPad as a prompt engineering tool. Write and test prompts for your own applications, and compare multiple versions.

When the AI engine emits code, LINQPad gives you several options to integrate that code into your query. This includes a source-control-style compare, so that you can clearly see insertions and deletions before updating existing code.
