  1. Can we have an option to keep the dialog "Navigate to query" open.
    It usally takes a few tries before I find the query I am looking for and it would be great if I could tick a box to keep it open after I dbl clicked to see the query

  2. In LPRun.exe we have the ability to only compile the script with the
    -compileonly switch.
    It would be nice if we had the same in the GUI IDE.

    Thanks in advance.

  3. If I want cross-execution (being able to F5, F5, F5) cache certain fetched web pages (only if they actually return a 200ish result). I can't make use of the existing very helpful cache method options.
    I don't want a failed attempt to be cached, and I want to be able to cache all
    successes.

    I'd like it if we could have the following signature off the existing Util class T CacheIf<T>(string key, Func<T> f, Func<T,bool> predicate, byref<bool> fromCache) also very useful IsCached(string key).

    A work around would be to litter the code with throws and try/catch.

  4. Minor suggestions or options,
    1: restart button (Execute, Break, Cancel, Restart) & customizable shortcut for it.
    2: results pane growing results backwards, the newest line(s) on top of the pane, this would help debugging and testing hardware (IoT:s) a lot.
    I know, there is auto scroll option, but LIOT (last-in-on-top) would be nice.

  5. The VsVim Visual Studio extension honours the "set relativenumber" instruction in _vimrc. It causes the current line to show the absolute line number, and all other lines are numbered relative to it.

    3
    2
    1
    584 // TODO: Removing this line breaks the app. We don't know why...
    1
    2
    3

    Something similar in LINQPad would be a lovely tweak!

  6. The intellisense dropdown uses the standard ListBox which calls SendMessage to the native listbox instance once for each new intellisense item. For many items, this can be incredibly slow.

    However, it seems that listbox supports pre-allocation for memory when a large number of items will be added:https://docs.microsoft.com/en-us/windows/win32/controls/lb-initstorage

    Making direct use of this API would enable performance improvements when a large number of intellisense items (up to 32k) are present - on my machine (32 core), a few thousand results in 10-30 seconds of delay every time a new intellisense dropdown opens, which is almost completely unusable. This fix could…

  7. Add ability to have pinned tabs show in a separate row.

    This allows easier navigation between queries when you have many open at one time.

  8. Hi
    I found an strange Exception eg. Bug in LinqPad.
    Following Code works:
    ´´´
    var e = foo();
    e.Dump();
    string foo() { return ""; }
    ´´´

    But if I add any Reference on *.dll over F4, "Additional References" and "Add/Browse"

    I get on .Dump() following Exception:
    "The type initializer for 'DumpExtensions' threw an exception."
    inner Exception: The invoked member is not supported in a dynamic assembly.

    This stops the practical using of Dump() in my Code.

  9. Today we use read only connections for production databases and it works well. But everyone once in a while we do need to change a value in a production db.
    Today we then connect with different credentials which takes a little time.

    My suggestion is a connection that linqpad enforces with fingerprint, windows hello or similar.
    So the connection is always there (and read/write) but every time I want to use it I have to authenticate. This would still be much faster then creating new connection (and in the other scenario I also have to remember to disconnect manually but…

  10. I have both LP5 and LP6, but I don't seem to have a way to write code snippets in C# 9.0 against .NET Framework 4.6/4.7/4.8. I'm fine with switching over to LP6 if/when I want to target .Net core or .Net 5/6, but I still need a way to test the latest language features against the older Framework versions.

  11. While LINQPad Version 6 was released in 2019, if you do a google search on "linqpad version 6 video", it shows all but one of the tutorial videos were produced before 2019. Only one was produced in 2020, and it focuses solely on databases.

    Instead, I want a tutorial video that includes the new version 6 hooks into visual studio. For example, the Rainer Stropek YouTube video "C# LINQ - Part 2- Basic LINQ Queries" has a nice elaborate visual studio Enumerable example with a JSON file. Under LINQPad 6, I'd like a video tutorial that shows how to load…

  15. Sometimes we need to specify custom project properties and environment variables for a query, for example, <EnablePreviewFeatures>true</EnablePreviewFeatures> and env vars DOTNET_TieredPgo=1. Please allow us to customize project properties and environment variables.

  16. Laundry list of desired features:

    1. Export Query to Dotnet SDK Project.
    2. Import / Export CSX (C# Script) Files
    3. Incorporate the C# Interactive Runtime and add immediate window, Like Visual Studio. Would be a huge help during debugging.
    4. Add Unit Test Management with support for MSTest, nUnit and xUnit projects.
    5. Seriously consider adding a Report Builder. LinqPad is already 75% of the way to replacing MS Access. This could put the nail in the coffin for MS Access.

  17. I like to format error messages and other output with Markdown to make it easier to create reports from code (I typically use LinqPad to free-hand test code and apply weird edge cases or explorer difficult bugs). Seein my output properly formatted will help me and my clients visual what their code is doing. And adding support to render PlantUML would also rock.

  18. Have a setting to format document on save.
    In visual studio I use codemaid and whenever I save files it formats them.
    Would be nice as one of those menu elements with a checkmark beside them.

  19. Something like in VS 2019, right click menu, "Convert to class". It would be so helpful for tasks like data exploration.

  20. Given that a natural thing to cache would be a download of a file, being able to use the asynchronous methods of HttpClient inside the Util.Cache delegate, without shortcircuiting with .GetAwaiter().GetResult() would be nice.
