Only a compilation unit can have top-level units. I couldn't find what caused this error. I don't know what this error means and if there is a solution. Can you help me? I am using Visual Studio Code with .NET9.0 version and C# coding language.

Hi @Enes Harun , Welcome to Microsoft Q&A,
Top-level statements are only allowed to run in a single file, usually the entry point of your application (e.g., Program.cs). If you accidentally put a top-level statement in another file, the compiler will throw this error. Make sure the file containing the top-level statement is the designated entry point. Move the top-level code to Program.cs. This can cause problems if the file containing the top-level statement is included by mistake or is not part of the project. If you have any further questions, please attach the code you used.

C# only support top level statements(code not contained in class definitions) in one file per project. These top level will be converted to main(){} statements at compile time. Typically it is the program.cs file.
