[vsfeedback]

[Happens in 16.4.0-preview-3.0-[29409.185.master]

This issue has been moved from a ticket on Developer Community.

[regression] [worked-in:Not sure about prev, 16.3 works for sure]

1. Get latest Int Preview Visual Studio.
2. git clone https://github.com/NuGet/NuGet.Client
3. Follow the instructions up to configure.ps1
4. Open NuGet.sln in Visual Studio.

After the solution was fully loaded the moment I started type, a yellow bar popped with, an error occured, see log file. Clicking on that opens the activity log in the default xml viewer.

In there I found the below. Note that there could be other problems, but this error was related to types of issues I was seeing.
