### How to Fix?

Step 1: Remove the existing website from solution

Step 4: Configure the project with a different name of the existing folder with the website files in it.

Step 5: Create the WebForms project

Step 6: Rename the created project with original website name

Step 7: Remove the project from the solution.

Step 8: Copy the generated csproj file to the original website directory

Step 10: Add the existing project in the original website directory to the solution

Step 12: Include the files to the project and exclude the ones that are not going to be part

Step 13: Add the needed references to the project. (Can use as reference the ones in the solution file, that exist for the original website)
