Asserting for equality anonymous types

I faced a problem asserting two anonymous types.

What I've done so far

• I have unit test project which sees the internals of my project under test, so anonymous types are visible to test project.
• I've read about anonymous types behaving more like structures(value types) rather than reference types here: Why anonymous types Equals implementation compares fields?

Yet again, while trying to test again equality following assertion exceptions occur:

1.

Assert.IsTrue(actionResult.Value.Equals(expectedActionResult.Value));

Expected: True But was: False

2.

Assert.AreEqual(actionResult.Value, expectedActionResult.Value);

Expected: <{ errorCode = -4, errorMessage = Invalid or Missing parameters within the request. }> (<>f__AnonymousType0'2[System.Int32,System.String]) But was: <{ errorCode = -4, errorMessage = Invalid or Missing parameters within the request. }> (<>f__AnonymousType0'2[System.Int32,System.String])

This is where I create real and expected result:

var actionResult = _systemUnderTest.GetToken(null) as JsonResult;
var expectedActionResult = 
    new JsonResult(new
    {
        errorCode = (int)ErrorCodes.InvalidOrMissingParameters, errorMessage = ErrorCodes.InvalidOrMissingParameters.GetDescription()
    });

What am I missing?
