Use the <xref:System.Resources.NeutralResourcesLanguageAttribute> to specify the neutral culture for the <xref:System.Resources.ResourceManager>. This approach avoids unsuccessful assembly lookups.

## Use the BinaryFormatter Class for Serialization
## Use XML Serializer Generator

If you must use serialization, use the <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class instead of the <xref:System.Xml.Serialization.XmlSerializer> class. The <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class is implemented in the Base Class Library (BCL) in the mscorlib.dll assembly. The <xref:System.Xml.Serialization.XmlSerializer> is implemented in the System.Xml.dll assembly, which might be an additional DLL to load.

If you must use the <xref:System.Xml.Serialization.XmlSerializer> class, you can achieve better performance if you pre-generate the serialization assembly.
If you use the <xref:System.Xml.Serialization.XmlSerializer> class, you can achieve better performance if you pre-generate the serialization assembly using the [XML Serializer Generator tool (Sgen.exe)](/dotnet/standard/serialization/xml-serializer-generator-tool-sgen-exe).
