 I had been convinced that you couldn't do this without installing clang, but it turns out that Microsoft wrote an extension that can format without using a heavyweight package.

wget --no-check-certificate -O packages-microsoft-prod.deb

sudo dpkg -i packages-microsoft-prod.deb

sudo apt-get update --fix-missing

sudo apt-get install -f #install with dependencies

sudo apt-get update

sudo apt-get install -y dotnet-sdk-5.0

but this not enoght, because I need to run code in a vm from github. to setup certificate:

sudo apt-get install --yes software-properties-common
sudo update-ca-certificates
sudo apt-get install socat -y
socat TCP4-LISTEN:4443,reuseaddr,fork,proxyport=3128
openssl s_client -showcerts -servername -connect </dev/null 2>/dev/null | sed -n -e '/BEGIN\ CERTIFICATE/,/END\ CERTIFICATE/ p'  >
cat | sudo tee -a /etc/ssl/certs/ca-certificates.crt
git config --global http."".sslCAInfo ~/
git config --global http.sslverify false
export GIT_SSL_NO_VERIFY=true

Then this error is gone:

fatal: unable to access '': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

The following is a list of valid distributions that can be installed.

Install using 'wsl --install -d <Distro>'.

Debian          Debian GNU/Linux

kali-linux      Kali Linux Rolling

openSUSE-42     openSUSE Leap 42

I need to insall Kali

wsl --install -d kali-linux

But of cource, the distro already little bit absolete in package refereces:

eugene@DESKTOP-78QLU8F:~$ sudo apt update

Err:1 kali-rolling InRelease

  The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <>

Reading package lists... Done

W: GPG error: kali-rolling InRelease: The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <>

E: The repository ' kali-rolling InRelease' is not signed.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

To fix this problem with brocken repo urls:

# download

sudo dpkg -i kali-archive-keyring_2022.1_all.deb
# remove downloaded file again

PENCIL UI prototyping free desktop app

format code in dotnet 3.1

dotnet tool install --global dotnet-format --version 3.1.37601 dotnet tool uninstall --global dotnet-format

Fyne on Windows 7

 For a cheap, obsolete environment I got a problem, fyne ui does not see my opengl. I remembered, the same problem appears for WFP, it also does not find hardfare graphics acceleration, but it is possible to run UI in software render mode. So do for fyne

after build app, copy software Mesa3D opengl.dll to folder with binaries, then it works.

This fix these crashes on start:

022/07/19 08:19:09 Fyne error:  failed to initialise OpenGL
2022/07/19 08:19:09   Cause: glGetBufferParameteri64v
2022/07/19 08:19:09   At: C:/Users/ep/go/pkg/mod/
Exception 0xc0000005 0x8 0x0 0x0
signal arrived during external code execution


Fyne Error
Fyne error: window creation error
  Cause:APIUnavailable: WGL: OpenGL ES requested but WGL_ARB_create_context_es2_

profile is unavailable
  At: C:/Users/ep/go/pkg/mod/


 I also recomend to compile fyne ui app with reduced drahics features to GLES


go build -tags gles .

 1. For first classes it did not realize context properly and it is good because he operate only names.

2. After read some logic that I use for app he can think logically already

3. For math equations he generateright code.

4. He start to know relations in object oriented model in time I wrote half of class decomposition

5. Lates class in screenshot he implemented without any moderation by his name. He dot the cnowledge about context and models to realize full group of rules and logic.

Despite a lot of jokes copilot from Microsoft works great for people that think.
