When I select Load Tools | Library Package Manager | Manage NuGet Packages for Solution (I want to install Glimpse), it comes up with Onlilne | NuGet official package source selected, I see this err msg in the middle pane:
Unable to cast COM object of type 'System.__ComObject' to interface type 'EnvDTE.DTE'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{04A72314-32E9-48E2-9B87-A63603454F3E}' failed due to the following error: Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).
Similarly, perhaps, my project's Output shows: Could not parse the configuration file. The error message is: 'Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))'. Try editing the file manually and then saving it.
What configuration file is it talking about? Web.config? I see nothing unusual in it...
Actually, the asp.net project compiles and runs, but the err msg is still disconcerting, and I don't know if it's a clue to the Nuget problem/if there's a connection there or not...
