Hello experts,
I'm using a .net html component in my Visual Basic app which relies on Microsoft.mshtml.dll and am getting this warning:
A reference was created to embedded interop assembly 'Microsoft.mshtml' because of an indirect reference to that assembly from assembly '3rdPartyHTMLSDK'. Consider changing the 'Embed Interop Types' property on either assembly.
3rdPartyHTMLSDK Embed Interop Types is set to FALSE
Microsoft.mshtml.dll Embed Interop Types is set to TRUE
If I set 3rdPartyHTMLSDK Embed Interop Types = TRUE I'll get tons of:
Reference to class 'blah' is not allowed when its assembly is linked using No-PIA mode.
If I set Microsoft.mshtml.dll Embed Interop Types = FALSE the warning is eliminated and not shown anymore!
Just was not sure if this is OK and won't cause runtime problems?
3rdPartySDK developer is out of business and can't ask them!
Generally, when interop types are embedded deployment of the generated interop dll is not necessary. However, if the option is set to false then you must deploy the interop dll. I suggest you test your own deployment with and without the interop dll.
Thanks dude,
...if the option is set to false then you must deploy the interop dll...
You mean if I set Microsoft.mshtml.dll Embed Interop Types = FALSE I need to distribute Microsoft.mshtml.dll with my app?
No, I'm talking about the generated interop dll. If you look at the property pane for your reference you should see what I'm talking about.
No interop.dll in my case!
It looks like Microsoft.mshtml.dll IS an interop dll. On my system I added a reference to the "Microsoft HTML Object Library" to a project and this is what was shown for the reference properties -
So I think you should test your deployment with/without Microsoft.mshtml.dll
And after adding the HTML reference to a VS2015 project on Win 8.1 -
Hey man thanks so much for help,
Thanks again :)
If interop types are not embedded I think you should deploy the dll. Whether or not the deployed dll is loaded will also depend on whether that assembly is present in the GAC of the target system.
