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.

The error message “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” typically occurs when trying to run or debug a process that is not using .NET Core.

.NET Core is a cross-platform open-source framework for building modern applications. It provides a runtime, libraries, and tools needed to develop and run applications that can target various platforms, including Windows, Linux, and macOS.

Causes of the Error:

• The target process is not configured to use .NET Core.
• The target process was not built or intended to run on .NET Core.

Solutions:

To resolve this error, you need to ensure that the target process is configured correctly to use .NET Core. Here are some possible solutions:

1. Verify that the target process is a .NET Core application.

Check the target process’s project file or build configuration to confirm that it references .NET Core and not another framework like .NET Framework.

2. Ensure that the required .NET Core runtime is installed.

Verify that the machine or environment where the target process is being executed has the necessary .NET Core runtime version installed. You can download the latest runtime from the official .NET Core website.

3. Check the target process’s runtime configuration.

Ensure that the target process’s configuration files (e.g., appsettings.json, web.config, etc.) are correctly set up for .NET Core and any dependencies are properly referenced.

4. Confirm the target process’s build environment.

If you are building the target process yourself, double-check that your build environment is correctly set up for .NET Core development. This includes using the appropriate SDK version and build settings.

Example:

Let’s assume you are trying to run a console application called “MyApp.exe,” and you encounter the mentioned error. To diagnose the issue, you would follow the solutions mentioned above.

You verify the project file of “MyApp” and notice that it is targeting .NET Framework instead of .NET Core. To resolve the error, you update the project file (e.g., MyApp.csproj) to target .NET Core and rebuild the application.

Upon running the updated “MyApp.exe,” the error should no longer occur, and the application should execute successfully using .NET Core.
