Use [FromUri] attribute to force Web API to get the value of complex type from the query string and [FromBody] attribute to get the value of primitive type from the request body, opposite to the default rules. ... So, Web API will try to get the value of Student type parameter from the query string.

Load method populates the client object directly with what it gets data from the server i.e. a collection object like ListItemCollection etc. but LoadQuery returns the data as a completely new collection in IEnumerable format. ... The ClientContext tracks the object IDs of the items and properties returned from the server.

Basically, if you pass a reference by value, then you can change the object it refers to and these changes will persist outside the method, but you can't make variable refer to a different object and have that change persist outside the method. Parameters in C# are passed "ByVal" by default.

I always used POST but according to the W3C standard, SOAP supports both POST and GET methods. ... SOAP requests (XML messages) are usually too complex and verbose to be included in the query string, so almost every implementation (for example JAX-WS) supports only POST.

"If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface." when we make any POJO class serialize then whenever we try convert it to make any kind of database understand it changes itself to stream of bits.

APIs are application interfaces, meaning that one application is able to interact with another application in a standardized way. Web services are a type of API, which must be accessed through a network connection. REST APIs are a standardized architecture for building web APIs using HTTP methods.
