How do I make a C# Console app build and debug in Visual Studio Code?

Jan 27 2025 12:55 PM

How do I make a C# Console app build and debug in Visual Studio Code?   

I have already built my C# Console App in Visual Studio Code.  The issue I have is when I reopen the folder where the project file is in Visual Studio Code and then rebuilding the code and debugging it again.    

Here is what I do and what happens.  After I open the folder where the project file resides,  I click on this to process the code to debug: 

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 0 7 . p n g 

(Icon showing the option to debug a solution)

And then I click on the appearing "Run and Debug" button

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 0 8 . p n g 

(image of the Solution Explorer panel with a buttin of "Run and Debug)

But then the bottom status bar says "Looking for CSS classes in the workspace..." followed by a percentage in paragraphs.  Why is this?  Why does this happen when there are no CSS classes at all and my project is a C# project?   

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 0 9 . p n g

(image of the status bar that appears at the bottom that says "Looking for CSS classes in the workspace..."

 

Why is this?  This is just a brief snapshot of some difficulties I find when I reopen a project after I have closed Visual Studio Code.  I have experienced other errors and problems in building and running my code.   

To continue, in order to deal with the project as a solution, I click on this icon to open the solution panel. 

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 1 0 . p n g

This seemingly allows me to view the solution.  As the following view appears, I click on the project.cs file and attempt a debugging session from there. 

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 1 1 . . . p n g 

With this file being displayed, I clicked on the menu option, Run -> Start Debugging   

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 1 2 . . . p n g  

Then, at this point, in the pop up option window that appears in the middle and top of the development environment, I pick "C#":  

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 1 3 . . . p n g 

Something went wrong and in the bottom right of my IDE, I get this message:   

h t t p s : / / l i k a b l e l o g i c . o r g / i m a g e s / l o s t / 1 4 . p n g 

Please advise.  What should I do now?
