Any way to ignore Possible Null Reference Exception warnings when using Assert statements?

I do not want to disable the warnings completely, just when it's in an Assert statement.

So for example if I have the following two lines

var someObject = GetObject();
Assert.IsNotNull(someObject, "someObject should not be null");
Assert.AreEqual(expectedValue, someObject.SomeProperty);

I'll get the possible null reference warning on the second line on someObject.SomeProperty. Is it possible to disable the warning when it is within a certain call, like Assert.AreEqual?

Since this is an issue with a lot of unit tests, I don't want to litter the tests with the ReSharper disable code.

Right now the only option I can think of is to change every Assert.IsNotNull call to be

var someObject = GetObject();
if(someObject == null)
{
  Assert.Fail("someObject is null");
  return;
}

Although this kind of seems to defeat the purpose of having Assert.IsNotNull in the first place. Just wondering if there is a better way.
