Description
I'm running a C# application which calls a VB class called wrapper.vb, which uses MS Word objects. This code was tried and tested and worked fine with .NET 4.8 but now breaks in .NET 5.
I have a variable: Protected m_wdApp As Object
When the class is instantiated, it calls:
Reproduction Steps
Public Sub New()
m_wdApp = CreateObject("Word.Application")
m_wdApp.Visible = False
m_outputFormat = DOC_FORMAT
End Sub
Expected behavior
Actual behavior
This throws the following exception
:
Now the above would be all very fine and well, if I wasn't able to actually look at the contents of the m_wrdApp and see that yes, they are all intact and are all visible in my watch Windows
.
Using the Immediate window, attempting to access any of these attributes from the Word object throws an error (as you'd expect).
However, if I ask VS to "add a watch" to one of the attributes, for instance this "Visible" which we currently need, it comes out with this convoluted watch name
:
Regression?
I should note that all of this worked fine before upgrading to .NET 5, so I'm wondering if this is either a bug or there are some new rules for dealing with late bound variables.
