0	With partial, we can physically separate a class into multiple files. It is true that Partial Class is used in auto code generation, one use can be maintaining a large class file which might have thousand lines of code. The class might end up with many lines and we don't want to create a new class with different name. public partial class Product { // 20 business logic embedded in methods and properties.. } public partial class Product { // another 30 business logic embedded in methods and properties.. } //finally compile with product.class file. Another possible use could be that more than one developer can work on the same class as they are stored at different places.

public partial class Product

{

    // 20 business logic embedded in methods and properties..

}



public partial class Product

{

    // another 30 business logic embedded in methods and properties..

}

//finally compile with product.class file.
