Can you look at your app.config or web.config across your solution?
Can you share the project?

Our error handling should probably call out the file name that is causing this to happen.

Hi there, hate to bring back things from the dead, I am encountering this issue on Nuget 3.4.4 under VIsual Studio 2015.3 I can't figure out what it's looking at.

[yishaigalatzer]

Can you open a new bug and share a repro? This might be unrelated.

Please share the full error output as well

Seeing same issue when I tried installing Xamarin.FFImageLoading.Forms v 2.2.10 package from Package Manager in VS2015
"An error occurred while reading file 'C:\source\SolutionName\ProjectName\ProjectName\packages.config': '.', hexadecimal value 0x00, is an invalid character. Line 1, position 1."

[Seeker1437]

See #3078 maybe?

[lennybacon]

#3078 Had the solution for me

& nuget.exe locals -clear temp
& nuget.exe locals -clear global-packages
& nuget.exe locals -clear http-cache

[Himura2la]

For dotnet core, use dotnet nuget locals --clear global-packages

[aalau]

For dotnet core, use dotnet nuget locals --clear global-packages

Had the same error and ran the above in developer powershell, then Build > Clean Solution, Rebuild solution.

Severity Code Description Project File Line Suppression State
Error NuGet Package restore failed for project Property: '.', hexadecimal value 0x00, is an invalid character. Line 1, position 1.. Please see Error List window for detailed warnings and errors.

why do I get this error and the file web.config contains nothing of that value, it all started when my collage pushed the project with the new tool used (reportViewer). now I cant restore all the packages and it shows this ! symbol to all references in the project
