How to resolve warning related to: Could not locate the assembly "Microsoft.Office.Interop.Outlook RRS feed

  • Question

  • Greetings:

    I have an application that uses OutLook to perform notification to users.  Right now I'm getting the following warnings and I'd like to get rid of them: 

    Warning:   'System.Runtime.InteropServices.FILETIME' is obsolete: 'Use System.Runtime.InteropServices.ComTypes.FILETIME instead. 

    For the warning above, how does this reference help me?  Do I need to download this or what?

    Warning:   Ambiguity between method 'Microsoft.Office.Interop.Outlook._Application.Quit()' and non-method 'Microsoft.Office.Interop.Outlook.ApplicationEvents_11_Event.Quit'. 
                      Using method group. C:\Projects\CCObjects\EmailProcessor\MailReader.cs

    Warning:   'System.Xml.Xsl.XslTransform' is obsolete: 'This class has been deprecated. Please use System.Xml.Xsl.XslCompiledTransform instead. 
              '    C:\Projects\CCControls\IP\IPManager.cs

    For the warning above, how does this reference help me?  Do I need to download this or what?

    Warning:  Unable to apply publish properties for item ""  -  AutoCheckControl

    What's needed here to enable publishing?

    Thanks for the help !!

  • Dear Tacotortilla,

    Thank you for answering the question.  This also resolved the issue I was running into.  I don't see why the direct cast should be necessary, probably because this is  COM object run via RCW by a Managed app?

    The moderators have a job to do and the intent was to redirect the person asking the question where help would be more readily found.  However, when a person's question is so simple and they need an answer ... give it to them. :)

    Good on you.
