can't do anything without seeing code
but why are you installing a preview package of EF core?
and why are you still on a preview version of .NET 8?
first step is update your .NET SDK and then install the packages appropriate for that version and not previews
okay i dont think is code issue you are right i need to check with the installtion
thanks bro it work now the dotnet installtion was not corrrect
