I don't always use Expression Trees, but when I do it's a big, long, unreadable Christmas tree 
I usually try to first declare all kinds of Expressions in variables and then use those, but it's usually a lost cause.

at one point I went as far as creating a limited programming language that resolved to code dom constructs instead of code. i called it slang and it could emit VB, C# or whatever. Unfortunately it was proprietary as part of a company's IP i worked for at the time or I'd be using it now.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

I only need them when working with some generic EF code.
Only once did I need it to output code and that was for an article

Code generation is sort of specialized, but I've always written code to write code.
My father was a toolmaker - he used to make machines that stamped sheetmetal for parts for large trucks and stuff. Weird job, but I think I've got it in my blood, as I prefer to make tools for other people to make stuff with, and that involves codegen a lot. =)

You're gonna hate me, but none of my generated code ever has Finalize() methods unless it's only C# and not the codedom.
but lately all my generation code has used the codedom, just so I can support VB
to be honest i don't even know VB syntax.

Why would I hate you for that? 
I've never written a finalizer in my life... Or thinking back on it, once, maybe.

I know VB6 and VBScript pretty well as a matter of necessity in the bad old days of microsoft land when every idiot fine programmer out there was using it to write bad software. It was usually my job to try and fix it, which really meant gleaning the functional requirements from undocumented source code and then rewriting.
Since .NET i've seen little of it, and I've had no use for VB.NET.

You wouldn't be asking me this is you saw the VB code I had to work with 
I used to love VB.NET, even after I started doing C#.
But after years of doing C# I now have to use it again and it's just lagging behind in pretty much everything.
The fact that Option Strict is off by default (causing much of my current problems) makes it bad by default.
Sub and Function As Object (or worse, just Function without an As clause because that's optional without Option Strict) feels weird.
The default indentation in Visual Studio sucks.
If something AndAlso
somethingElse Then
DoSomething()
ThisIsAlsoAFunction
End If Keywords like End Function, AndAlso and OrElse are unnecessarily long.
Don't even get me started on lambda's! collection.Where(Function(x) x.Something) vs. collection.Where(x => x.Something)!
Meanwhile, shortcuts like inline ref variables don't make it to VB.
Because it's not case sensitive myVar and MyVar are the same, meaning I sometimes need to think just a bit harder to name my variables.
Static classes don't exist, you need a Module, but that's slightly different (in that functions become public without the need of using the class name) making a Private Class with Private Sub New() the closest to a static class.
And please don't use the default VB namespace Modules that are imported by default!
If I'm honest, I've never seen good VB code that I didn't write myself, while I've seen some good C# code.
Microsoft is quickly dropping support for new platforms and VB.
It's only just been added to .NET Core with version 3, together with WinForms support.
Try finding (good) code samples for VB online.
Even newer Visual Studio functionality, like code cleanup, is not available for VB.
All in all, I have no reason whatsoever (or even a choice) to use VB in any modern software development.
Let me end with a small positive note for the language I started in.
One thing VB does right (in WinForms development) is Sub MyButton_Click(sender As Object, e As EventArgs) Handles MyButton.Click, which I find more clear than the C# way of adding a handler in the designer.

Those aren't even very long.

Here I have to really disagree with you, having two variables like myVar and MyVar isn't just against MS naming convention, it's also honestly quite stupid. I've seen more than one bug coming from this.
Sander Rossel wrote: If I'm honest, I've never seen good VB code that I didn't write myself
There are two ways I can take that, and in either case I believe I have to take offence.

Property MyProp with backing field myProp, MS uses it too 
The _myProp style was disbanded by MS in VS2010 I think, at least in C#.
It's really not that weird.
In C# I never need backing fields because all my properties are auto-properties.
Of course, in VB, support for auto-properties is limited so I still need them from time to time

I can live with the verbosity, but when you ask me what's wrong with VB I'm going all out 
The incomplete tooling compared to C# is something I blame on MS.

And they use m_MyProp and _MyProp as well. I didn't say they live according to their own rules.
Sander Rossel wrote: The _myProp style was disbanded by MS in VS2010 I think, at least in C#.
I think it was still around 2013, those rules change every few years anyway.
Current rules states no prefixes and no underscores at all, but they also state that fields should be Pascal cased, and that naming should avoid confusion. And at least the last part makes proper sense no matter what. Especially since the same name with different case also tends to confuse intellisense.
Sander Rossel wrote: in VB, support for auto-properties is limited
Is it? Works fine for me since long.
And another comment on your previous post: You shouldn't blame the tool for the tools using it.
If VB goes out of fashion they will just start using a different language.
It seems at the moment that C# isn't it, but rather Javascript and Python. Or whatever is taught in the schools at the moment.

Seriously though, you'd have to change all the Visual Studio defaults and anyone working with your code after that will curse you for doing so
Jörgen Andersson wrote: but they also state that fields should be Pascal cased
Fields Pascal? Where did you find that? I always camelCase them and never seen different.
Intellisense works fine for same name variables that are differently cased, at least in C#
I don't think I do it a lot though, but I wanted to do it in VB because of the auto-property issue I mentioned.
I also use it when, for example, I have a property MyResult and then in a method I calculate myResult in a local variable.
Jörgen Andersson wrote: Is it? Works fine for me since long.
Try to set Public ReadOnly Property MyProperty As String (there's that verboseness again).
I figured it out, you have to set the invisible field _MyProperty

I'm not sure what you mean, but I never blamed tools.
I blame VB programmers for writing abysmal code

Names of Type Members | Microsoft Docs[^]
Note though something I didn't notice yesterday: design-guidelines wrote: The field-naming guidelines apply to static public and protected fields. Internal and private fields are not covered by guidelines
But guess how the private invisible backing variable to the autoimplemented property looks like. Also in C#. 
So even if they removed that guideline some years ago, the compiler still does it.

That's the point.
If I want to remove a handler in VB I just remove the handler and be done with it.
In C# I have to visit two places and if I remove just the addhandler I'm left with some handler that's never triggered!

no typedef!
dt = new KeyValuePair<KeyValuePair<CharFA<TAccept>, CharFA<TAccept>>, RegexExpression>(
new KeyValuePair<CharFA<TAccept>, CharFA<TAccept>>(
dt.Key.Key,
dt.Key.Value),
tt[dt.Key]);
I want to make the C# language team have to declare things like this all day long.

Doesn't work. Using requires hard types. It can't use the type parameter TAccept
FOr it to be able to do that it would have to work like C++ where typedef kinda runs like a preprocessor macro (as do source templates)

Mmm... Like Harold said, compiles for me!
using System;
using ListI = System.Collections.Generic.List<int>;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
var f = new ListI();
f.Add(1);
Console.WriteLine(f.Count);
}
}
}

That only works because int is a hard type.
You can't use using with type parameters.
You cannot do using ListT = IList<TAccept>;
You can in C++ because template stuff basically works like source macros internally, which means they don't have to "resolve" type parameters, they can just preprocess/replace them in whatever context they're used in. C# does not treat generics like source macros so it cannot do a C++ style templated typedef

Mmmm.. you mean typedef can't be generics, didn't you?
ha well... true that...
On a side note, one that is only vaguely relevant. When generics got out I went all out on generics... and my code became an increasingly complicated and unusable bag of noodles...
Then I realised generics are better when used in moderation!
Works for me, at least!

Unfortunately, when doing functional style programming heavy use of generics is pretty much unavoidable.
C++ does so much better at this kind of thing. I wish C# would add "template" to the language and allow you to do source style templates like C++ as well as generics (which are binary)
Source level templates are simply far more flexible. You can do things like that typedef, you can do things like get the compiler to make complicated calculations like generating parse tables at compile time (see the Spirit C++ parser framework for an example), and you can do partial template specializations and just all kinds of things you'll never be able to do at the binary level.
It's unfortunate. I love C++ for this stuff. I wish other languages had it.
Ironically, Java/J2EE comes close with their templates, since they are source level but they are so poorly architected that they're a bad joke.

You can use an interface for TAccept to represent a wide variety of types, am I right? Albeit it is more restrictive that a completely wild symbolic type ...
