When do i need to download the .Net core Runtime?
(1 answer)
Closed 2 years ago.
So a really basic question:
I wrote a c# console app. Not completly basic. There several classes outside the Programm.cs.
Now I wanted to show it to some friends so I send them zipped folder and and told them to go into \bin\Debug\netcoreapp3.1 and open the .exe file.
This works for me, but not for 2 of my friends who tried it.
A new windows opens and closes right away.
They seem to have the .Net framework installed.
Is there a way to open it without having install visual studio?
Thanks
Solved:
The issue was that .Net Core Desktop Runtime wasn't installed
Thanks everyone
You should publish your project. You will find the option to publish based on your visual studio.
Once your code is published, open \bin\release\netcoreapp3.1\publish..
And share this complete published folder

How can I run an EXE program from a Windows Service using C#?
(9 answers)
Closed 5 years ago.
I'm currently working on a project to automatize my backup to run only under certain circumstances. Therefor I'm writing a Windows Service in C# using Visual Studios 2015. I already got my requirements set and now I can't get my Service to run sdclt.exe (the Microsoft Default Backup). I already searched for a solution but i only found people saying that Windows Services can't start .exe anymore. Does anyone here have an idea how it might still work?
Thank You
you can create BatchFile that Run sdclt.exe or use System.Thredin.Process to Run that exe. use verbs if require to run with administrator rights.

How do I run a Python script from C#?
(9 answers)
Closed 7 years ago.
I am completely new to Visual Studio and C#, so I apologize in advance if this sounds like a dumb question. I am trying to develop a Windows Forms Application such that when I click a button, a Python script is run, performing data analysis on some files, with the eventual goal of displaying that data as a graph on the Windows Forms Application after the button is clicked.
My question is: how do I get the python script to run when the button is clicked from the Windows Forms Application?
Yes, it is possible.
You can create a process that runs python shell.
