Are you waiting for the page to load first? You should bind a function in your code to wait for the page to load, them click the button:

static void form1_Load() {
    // ...
    webBrowser1.onDocumentReady += webBrowser_DocumentReady;
}

static void webBrowser1_DocumentReady() {
    webBrowser1.Document.GetElementById("publishButton-ns").InvokeMember("Click");
}
