Do you get the error without any includes? I suspect there may be a mapping error between your database and your EF entities.

I have a field float when i comment the field works

The float type in C# maps to the real column type in SQL:
SQL Server Data Type Mappings - ADO.NET | Microsoft Docs[^]

Confusingly, the float data type in SQL maps to the double type in C#.

You'll need to modify your C# property to use the correct type that maps to the SQL column type.
