@aho , thank you very much for your help with #csharp and #VScode and #Ubunutu and #apt ...

Your time, as mine, on the clock, is the same. Being summer and you being more north and little more east, I guess, your daylight starts earlier. It is gray morning here. Raining. And I am enjoying a coffee.

Let us make a step back and consider what I am trying to do.

(I think we have discussed before the possibility of having our conversation hybrid: Finnish Czech. I may remember, you did not like the idea then.)

A student who is close to me and who uses Ubuntu is required to pass a test on a school computer: #Microsoft - #Windows - #VisualStudio - C# . I don't like what the school requires from them, but here we are.

So, I have been trying to create an enviroment on their (and in parallel on mine) computer to prepare for the test. After more than ten hours, no success. The student borrowed a Windows computer and prepares for the test on it. The situation is solved for the moment and is not fully solved for the future. The course continues.

I am heading to the conclusion that, in general, it is better to have access to a Windows computer for this and other tasks which somehow suppose that Windows is a standard, to use this computer for such dirty work, and not to try to make a Linux machine to do whatever Windows machine may be doing.

Any thoughts on this? @aho , or anybody?

Using the `extension` keyword in #csharp 14 is kind of awkward. It would be nicer to be able to use it as a top-level declaration without the wrapping static class.

Before you say, "where would they exist in that case?”, each namespace would have a catch-all static class that would hold these extension methods if there is no wrapping class. #dotnet already generates a `Program` type, this would be another one of those.

Be honest, who here remembers that #csharp introduced a file keyword? #dotnet

Hello again, old friend.

I'll be diving into C# tomorrow to try to help a developer parameterize their ad hoc query so it doesn't generate thousands of query execution plans.

The things I do to keep SQL Server humming along...

Has someone adapted #csharp source generators to bring a macro-like experience to #dotnet?

I’m excited to share the little reactive programming library I built for #csharp and #godot, although it will work in any c# project.

This will guarantee deterministic execution and defer mutations when executing bindings to guard against reentrancy issues.

@aho , thank you. I am down now. Several hours trying to set up #VSCode for #csharp on #ubuntu . No success...

Asi za to mohlo dotnet.sh v /etc/profile.d :

# Add dotnet tools directory to PATH
DOTNET_TOOLS_PATH="$HOME/.dotnet/tools"
case "$PATH" in
*"$DOTNET_TOOLS_PATH"* ) true ;;
* ) PATH="$PATH:$DOTNET_TOOLS_PATH" ;;
esac

# Extract self-contained executables under HOME
# to avoid multi-user issues from using the default '/var/tmp'.
[ -z "$DOTNET_BUNDLE_EXTRACT_BASE_DIR" ] && export DOTNET_BUNDLE_EXTRACT_BASE_DIR="${XDG_CACHE_HOME:-"$HOME"/.cache}/dotnet_bundle_extract"

Zatím jsem ho přejmenoval na fuj_dotnet_s_h a už je PATH hezčí:

$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

Ale asi jsem to dovil Majkrosoftu to tam dát. Ach, ach, já trubka. Myslím, že mám skončit a dát si přestávku.

Kde se tam vzalo /home/něco/.dotnet/tools ?

An error occurred while installing .NET: The distro Ubuntu 24.04 does not officially support dotnet version 9.0.304.

**tymoty** @tymoty@f.cz · 7 sept.

#csharp #VSCode #Ubuntu @theron29 , možnosti

1) Možná ten 'bug' lze ignorovat. Vrátit se k původním 'snap'. Vyzkoušet.

2) Nainstalovat 'dotnet 9' podle Majkrosoftu.

3) Hrát si s 'config.json'.

4) ?
