Issue: 💡 Feature request ->Omnisharp does not recognize "asp-for" tag error

## Is your feature request related to a problem? Please describe.

Hello!! I am programming in a .cshtml view and the IntelliCode does not recognize the asp-for tag.

This is in Visual Studio 2022:

But in VSCode:

I know what the error is because it is "Client_Id" with capital letters. But the problem is that the OmniSharp in VSCode does not recognize the error. When I put the mouse over it does not make me the reference to the error as it is Visual Studio.

This reference works in Visual Studio:


The error does not appear in the "errors" console either.

## Describe the solution you would like

It's frustrating when it doesn't recognize an attribute, variable, etc

## Applicable Scenarios

That the description appears when hovering, and that it recognizes the variable, this visual studio does it

## Describe alternatives you've considered

I use Visual Studio and not VSCode
