This is a run time type object you passed in explicitly.

Here, T was inferred at compile time, not run time.

It is expected behaviour for the given code. Whether it is intended
behaviour is a question you need to answer, since only you know the
provenance of this code.

3 arguments => Parser.TryParse(Type,string,out object)

You are calling TryParse with 2 arguments, => Parser.TryParse<T>(string,
outT) is the only candidate.
The first argument type is a string (input), the second argument type is
an object. Therefore, T is inferred to be of type System.Object (==
object).
