[Tutorial & Sample] Using Unsigned Integers in OData
Unsigned integers can be useful in many ways, such as representing data sizes, resource handles and so on. Though OData V4 only supports signed integer natively, the protocol offers a flexible way called type definition to allow users to ‘define’ unsigned integer types themselves. As an example, we know that any UInt16 integer can be represented by the primitive type Edm.Int32. Thus by type definition, we can define a new type named MyNamespace.UInt16 whose underlying type is Edm.Int32. By doing so, we can store and serialize UInt16 integers as Edm.Int32 ones. There are three advantages of leveraging type defini...

Open complex types allow customers to add undeclared properties in the payload. And in the future they can use these properties in queries. This blog is intended to provide a step by step guide for you to use the open co...
