monodevelop-language-server-addin's Issues

Collection was modified error

The following error was logged. I suspect that a language client document was closed at the same time as the solution was closed, and the session was removed when the document closed whilst the sessions were all being closed. The code should convert the enumerable to an array and also check if it still in the dictionary to catch it the case where it has already been removed.

Async operation failed

ArgumentNullException

Saw this in the IDE log when running VS Mac 7.6. Presumably the document had no name or associated filename.

Null reference exception logged by ParameterInformationWindow

The following error is logged when typing in Visual Studio for Mac 7.4.

An unhandled exception has occured. Terminating Visual Studio? False
System.NullReferenceException: Object reference not set to an instance of an object
  at MonoDevelop.Ide.CodeCompletion.ParameterInformationWindow+<UpdateParameterInfoLocation>d__14.MoveNext () [0x0002b] in monodevelop/main/src/core/MonoDevelop.Ide/MonoDevelop.Ide.CodeCompletion/ParameterInformationWindow.cs:109

On master this is handled with a null check:

mono/monodevelop@092db73

However MonoDevelop should be debugged to understand why the language server is causing a null reference exception here.

Handle no language clients being available

VS Mac 8.3 - with the language client installed and no other language clients available - opening a document fails since the LanguageServerServices could not be initialized.
