I have getting this error:

Fatal error. System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.    at System.Globalization.CompareInfo.Compare(System.ReadOnlySpan`1<Char>, System.ReadOnlySpan`1<Char>, System.Globalization.CompareOptions)    at System.Globalization.CompareInfo.Compare(System.String, System.String, System.Globalization.CompareOptions)    at System.String.Equals(System.String, System.StringComparison)    at Microsoft.DotNet.Cli.Utils.UILanguageOverride.Setup()    at Microsoft.DotNet.Cli.Program.Main(System.String[])

Hi @AsynchronousTexx 229 , Welcome to Microsoft Q&A,

You can choose to use a command line or you can use the compiler to create it directly.

1.Create a directory first

mkdir testProject
cd testProject
dotnet new console

edit program.cs then

dotnet run

2. https://github.com/dotnet/docs/blob/main/docs/core/tutorials/with-visual-studio.md

Create a .NET console app project named "HelloWorld".

Start Visual Studio 2022.

On the start page, choose Create a new project.

On the Create a new project page, enter console in the search box. Next, choose C# or Visual Basic from the language list, and then choose All platforms from the platform list. Choose the Console App template, and then choose Next.

In the Configure your new project dialog, enter HelloWorld in the Project name box. Then choose Next.

1. In the Additional information dialog:

• Select .NET 8 (Preview).
• Select Do not use top-level statements.
• Select Create.

Best Regards,
