Hi @vishnu
We analyse the C# in cshtml as part of the security analysis but not for code quality rules as these files should contain minimal amounts of C# code. In Sonarlint for VSCode the cshtml files are analysed for html issues but not C# ones, this is currently not the case in Visual Studio which is why you are seeing no issues.
We are considering extending full analysis to cshtml files in the future. To help me understand the need, what types of issues are you concerned about in your cshtml?
