.net – Failed while publishing clickonce application

clickoncenetwpf

I get the following error while trying to publish a wpf clickonce application.

Error
1
Publish failed with the following error: Unable to cast COM object of type 'EnvDTE.DTEClass' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{6D5140C1-7436-11CE-8034-00AA006009FA}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

The error happens if I try to publish to an FTP site and also if I try and publish to the local file systems.

Any ideas? Googling doesn't seem to produce any useful results.

Best Answer

The EnvDTE.DTEClass is some functionality that should be provided by Visual Studio. I have a few suggestions:

Create a new WinForms project (just an empty Form) and try to publish that.
Try Repairing or Reinstalling VS
Have a lookt at Building ClickOnce Applications from the Command Line

Android Sharing on Twitter

There are a number of ways to implement this.One may be simply open up http://twitter.com and share tweets in a single intent such as..

Intent tweet = new Intent(Intent.ACTION_VIEW);
tweet.setData(Uri.parse("http://twitter.com/?status=" + Uri.encode(message)));//where message is your string message
startActivity(tweet);

Or,

Intent tweet = new Intent(Intent.ACTION_SEND);
tweet.putExtra(Intent.EXTRA_TEXT, "Sample test for Twitter.");
startActivity(Intent.createChooser(share, "Share this via"));

Or,

String tweetUrl = "https://twitter.com/intent/tweet?text=WRITE YOUR MESSAGE HERE &url="
                    + "https://www.google.com";
Uri uri = Uri.parse(tweetUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
