Hi,

I have an ASP.NET Core 2.1 web application. Today when I try to debug I got this error. I just made new additions last week, it was working without any problems. What is wrong with it?

The target process exited without raising a CoreCLR started event. Ensure that the target process is configured to use .NET Core. This may be expected if the target process did not run on .NET Core.

Thank you.

Hi @Cenk

You can try to use the following methods:

Try to clear and rebuild the project or restart the application.

Try to create a new Asp.net Core 2.1 application with the default template, then check whether it works well or not.

Try to use dotnet --list-sdks and dotnet --list-runtimes commands to check the installed SDK and runtime. If you can't find the specofoed SDK or runtime, you can find them from here, try to install them. Refer to this thread.

core 2.1 has been out of support for a long time. maybe your hosting environment no longer supports it.

you should upgrade to a supported version. .net 6 LTS being the lowest possible.

The program '[13496] WebApplication3.exe' has exited with code 2147516566 (0x80008096).

I am still getting above issue
