I am moving code that already exists in two projects and compiles without errors in each project. I’ve created a dll and am moving the common parts from the applications to the dll.

In each of the applications there is a class which contains:

public DataRow NodeRow;

Then in the class constructor:

NodeRow = null;

In the applications this builds without warnings or errors, however when I move the same class to the dll, I see warnings on:

NodeRow = null;

The warning is:

warning CS8625: Cannot convert null literal to non-nullable reference type.

I’m quite new to C# so please excuse me if this is a really newbie issue.
