The CodeDom provider type "Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider" could not be located

🐞 Common Issue: CodeDom Provider Not Located

Have you ever come across the error message "The CodeDom provider type 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider' could not be located"? This error usually occurs when you are working on a WebApi project using Visual Studio 2015, and you change the build output path from "bin" to "bin\Debug". Don't worry, you're not alone in facing this problem! Let's dive into the issue and find a solution.

🔍 Understanding the Issue

When you change the build output path in Visual Studio 2015, the CodeDom provider fails to locate the necessary files to compile the code. This results in the mentioned error message popping up. The issue stems from the fact that any output path other than "bin" causes the CodeDom provider to malfunction.

👣 Step-by-Step Solution

To resolve this issue, follow these simple steps:

1. Create an empty WebApi project in Visual Studio.

2. Navigate to the project's properties.

3. Under the "Build" tab, you will find the "Output path" option.

4. Change the output path back to the default value: "bin".

5. Save the changes and rebuild the project.

6. Run the project and check if the error message disappears.

That's it! By reverting the output path to "bin", you have successfully fixed the CodeDom provider issue.

🔧 Alternative Solution

If you still need to change the output path, there is an alternative solution. You can have another output path to any directory as long as you also keep a build in the default "bin" folder. This workaround ensures the CodeDom provider can locate the necessary files and avoids the error message.

🚀 Ready for Deployment?

While following the above steps will help you overcome the issue during development, it's crucial to consider its impact on actual deployment. Changing the output path might lead to problems during deployment, so it's strongly recommended to stick with the default "bin" folder for simplicity and compatibility.
