Exception when opening C# Interactive

[MScudeller]

It tells me an exception happened and that I should see the log to know what happened:
<entry> <record>1135</record> <time>2018/09/13 13:36:18.108</time> <type>Error</type> <source>Editor or Editor Extension</source> <description>System.NullReferenceException: Object reference not set to an instance of an object.&#x000D;&#x000A; at HotCommands.LastEditHandler.GetCurrentFilePath() in C:\Projects\HotCommands\HotCommands\Listeners\LastEditTextViewCreationListener.cs:line 54&#x000D;&#x000A; at HotCommands.LastEditHandler.RecordLastEdit(Object sender, EventArgs e) in C:\Projects\HotCommands\HotCommands\Listeners\LastEditTextViewCreationListener.cs:line 45&#x000D;&#x000A; at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent(Object sender, EventHandler eventHandlers)&#x000D;&#x000A;--- End of stack trace from previous location where exception was thrown ---&#x000D;&#x000A; at Microsoft.VisualStudio.Telemetry.WindowsErrorReporting.WatsonReport.GetClrWatsonExceptionInfo(Exception exceptionObject)</description> </entry>

I just got the same exception. Any idea what's causing this?

Um. Not sure. What version of Visual Studio are you experiencing this with?

I also get it. I'm on latest 2017 (15.8.7). HotCommands version is 2.1.5. The "demangled" exception trace is:

System.NullReferenceException: Object reference not set to an instance of an object.\r
   at HotCommands.LastEditHandler.GetCurrentFilePath() in C:\Projects\HotCommands\HotCommands\Listeners\LastEditTextViewCreationListener.cs:line 54\r

--- End of stack trace from previous location where exception was thrown ---\r

In my case I use:

• VS Professional 2017 version 15.7.6
• HotCommands version 2.1.5
