Unknown error in visual studio 2022

It seems like you're experiencing an issue with your C# code in a .cshtml file. The light gray color usually indicates that the code is being treated as a comment or an inactive portion of the code. Additionally, the code being executed immediately when the page loads suggests that it might be placed in the wrong section of the file.

Here are a few suggestions to help resolve this issue:

1. Check Razor Syntax: Make sure that you're using the correct Razor syntax for embedding C# code within the .cshtml file. Razor code is typically enclosed in `@{ }` or preceded by `@` symbols.

2. Placement of Code: Ensure that your C# code is placed in the appropriate section of the .cshtml file. If you want the code to run only when certain conditions are met or in response to specific events, it should be placed within the appropriate Razor blocks (`@if`, `@foreach`, `@while`, etc.) or event handlers.

3. Verify File Extension: Double-check that you're working with a .cshtml file, which is specifically used for Razor views in ASP.NET MVC. If you have a different file extension, such as .cs, it might not be recognized as a Razor view and won't execute the C# code correctly.

4. Syntax Errors: Check for any syntax errors in your C# code. Even a small mistake can prevent the code from executing correctly. Ensure that all the necessary brackets, semicolons, and other syntax elements are properly placed.

5. Framework Version: Confirm that you're using a compatible version of the .NET framework and Razor syntax. If you recently upgraded your framework or tooling, some changes in the Razor engine might affect the behavior of your code.
