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.

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.

Either Options Some None Map Reduce...

Dark Theme like Visual Studio 2019 Dark

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.

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.

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.

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

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.

Add the ability to copy (Ctrl+Drag) and move (Drag) .LINQ files within the MyQueries tab across folders via drag and drop. Currently, to move a file, one must open the file, use "Save As," and then delete the original.

I know I can use File Explorer to do this, but it would be nice if it could be done right there in the MyQueries tree.

Pin scripts - like chrome tabs.

I use 4 keys scripts to do my job every day. Every day I need to open these and order them how I like. Great if I could pin them like Chrome tabs

The keyboard shortcuts page (Help -> Keyboard/Mouse Shortcuts) is always black text on a white background.

Since the page is just HTML (%LocalAppData%/Temp/LINQPad6/KeyboardShortcuts.html), supporting dark mode should just require a bit of CSS. I tried the following and it matches LINQPad's dark mode reasonably well, feel free to copy it as-is:

@media (prefers-color-scheme:dark) {
body { background-color: #1E1E1E; color: #DDDDDD; }
em { background: #4C4C00;}
}

I would like an option to disable all NuGet related prompts. I would like to be able to run a script without having to worry about NuGet package download confirmation or any particular license attached to the NuGet package. I find these annoying since I use packages from a private feed.

It would be nice to have the Entity Framework 6 driver back in Linqpad 6, since EF6 now also targets netstandard 2.1.

As an avid user of Jetbrains, I'm always looking for things that are integrated with jetbrains (mostly for my key/vim bindings). Would it be reasonable to make this a plugin so we could use some of the functionality from within the IDE?
