== Why is this an issue?

Calling ``++GetType()++`` on a nullable object returns the underlying value type. Thus, comparing the returned ``++Type++`` object to ``++typeof(Nullable<SomeType>)++`` doesn't make sense. The comparison either throws an exception or the result can be known at compile time.


=== Noncompliant code example

[source,csharp]
----
int? nullable = 42;
bool comparison = nullable.GetType() == typeof(Nullable<int>); // Noncompliant, always false
comparison = nullable.GetType() != typeof(Nullable<int>); // Noncompliant, always true

nullable = null;
comparison = nullable.GetType() != typeof(Nullable<int>); // Noncompliant, calling GetType on a null always throws an exception
