Describe the bug

dotnet run is unable to run the program due to error but dotnet build works fine.

To Reproduce

0. Use dotnet 6.0
1. Create a new dotnet project by do dotnet new console
2. Write some random program (Here's mine)

// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");

3. Run it by do dotnet run

Exceptions (if any)

System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string. (Parameter 'startIndex')
   at System.String.Substring(Int32 startIndex, Int32 length)
   at System.String.Substring(Int32 startIndex)
   at Microsoft.DotNet.Tools.Run.RunCommand.TryGetTargetArchitecture(String runtimeIdentifier, Nullable`1& targetArchitecture)
   at Microsoft.DotNet.Tools.Run.RunCommand.GetTargetCommand()
   at Microsoft.DotNet.Tools.Run.RunCommand.Execute()
   at Microsoft.DotNet.Tools.Run.RunCommand.Run(String[] args)
   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, TimeSpan startupTime, ITelemetry telemetryClient)

This is a duplicate of #23004, which seems to be triggered by a locale setting. On the Raspberry Pi, you might be able to work around the bug by changing the LANG or LC_COLLATE or LC_ALL environment variable.

Thanks @KalleOlaviNiemitalo, for Windows PowerShell I found the environment variable DOTNET_SYSTEM_GLOBALIZATION_INVARIANT being true solves the issue as current workaround.

> $env:DOTNET_SYSTEM_GLOBALIZATION_INVARIANT='True'
> dotnet run

sometimes dotnet program won't even run

The environment variable DOTNET_SYSTEM_GLOBALIZATION_INVARIANT is not really working well for me, especially when my project contains string sorting because there won't be cultures data at all under this mode, according to this document: https://github.com/dotnet/runtime/blob/main/docs/design/features/globalization-invariant-mode.md

I have the same problem as well. I solved it by changing Date format on windows to Christian era and Regional format to US I hope it will help you. refer https://docs.microsoft.com/en-us/dotnet/core/runtime-config/globalization

Thank you, This helped me too

This happened on my friend's machine where he used to use Thailand as his regional format. The date on his machine used to be written in Thai, Upon changing the regional to English (United States), the problem's solved.

We're on SDK v7

Folks - if you're having this issue can you please comment (or edit your existing comments) with

• your system's Locale/UI Culture
• the SDK version you're using?

I think this was fixed in 7.0.200 by #27566, so if you're using 7.0 SDKs make sure you're at least on that version.

My locale is Thai/Thai. SDK is 7.0.400. I had the issue while try to install Microsoft.dotnet-interactive.

dotnet tool install --global Microsoft.dotnet-interactive --version 1.0.446104
