NuGet Warning NU5133

Example

Warning NU5133: NuGet.exe file on path \Downloads\nuget.exe needs to be unblocked after downloading.

Issue

When downloading a file on Windows, in this case nuget.exe, through a web browser, the Mark Of The Web may be added. This makes Windows consider that flag as potentially dangerous despite coming from a well known source such as nuget.org. As a consequence some nuget.exe pack operations may work incorrectly.

Solution 1

Right click on your downloaded copy of nuget.exe and select "Properties".

NuGet Properties

Now tick the Unblock then press apply.

NuGet Unblock

Now try again the pack operation.

Solution 2

From powershell terminal run Unblock-File -Path .\Solution\nuget.exe
