Repro -- WebBrowserAH2.cs etc
Repro app attached.
Compile *without* /t:winexe, e.g. with:
gmcs /pkg:dotnet WebBrowserAH2.cs Utils.cs
Run
Hit Test->Dump All Properties
Use File->OpenUrl (!not OpenFile due to #2), wait until loaded.
Hit Test->Dump All Properties
Close
Inspect the console output, it includes the DumpAllProperties output from before the Form is shown, and the two times when the menu item was selected. See various errors reported. In the dump from before painted, see #1, #3, #4. In the dump after document loaded see #2 etc.

BTW this app aborts at exit with the following, as do other similar apps. Do you want that reported separately? [[ Stacktrace: at (wrapper managed-to-native) System.__ComObject.ReleaseInterfaces () <0x00004> at (wrapper managed-to-native) System.__ComObject.ReleaseInterfaces () <0xffffffff> at System.__ComObject.Finalize () [0x00000] in C:\cygwin\tmp\monobuild\build\BUILD\mono-2.0\mcs\class\corlib\System\__ComObject.cs:68 at (wrapper runtime-invoke) System.Object.runtime_invoke_void__this__ (object, intptr,intptr,intptr) <0xffffffff> This application has requested the Runtime to terminate it in an unusual way.

The following properties don't work in WebBrowser, as tested in Windows 2.0preview+. Not tested on Linux (I should really think about getting a working WebBrowser setup on Linux!). Only #2 would appear possibly platform dependent. BTW these properties were most not implemented in 1.9, so no regression. 1) get_DocumentStream uses StreamReader to read from a string DocumentText, thus uses the string as a path! BTW once a page is loaded the error from #2 occurs when this property is accessed. If using DocumentText to get the data it would need to be something like: string text = DocumentText; if( text == null) return null; System.Text.Encoding enc = … … Stream s = new MemoryStream(enc.GetBytes(text), false); But what encoding to use? Is Document.Encoding valid? Ideally the raw content as downloaded by the browser would be returned… set_DocumentStream untested due to #2. 2) DocumentText (get_ and set_) fails with InvalidCastException. base.WebHost.Document.FirstChild apparently returns a Mono.Mozilla.DOM.Node, which implements INode (and IDisposable) but not IElement… 3) DocumentTitle (get_ and set_) fails with NRE before first painted. 4) DocumentType (get_ and set_) fails with NRE before first page loaded.
