When trying to sync or pull our repository from remote, it fails with the following error:

The pull operation failed, see Output Window for details.

In the output window, the error is the following:

Go to Visual Studio’s Tools, and then Options, search for ‘Git’ in the searchbar.

Select the Git Global Settings option, and find the ‘Credential helper’ setting, and set it from ‘Unset’ to:

GCM For Windows

This should solve your problem.

NuGet lokális Cache törlés egyszerűen

by

Amennyiben azt feltételezzük, hogy a Visual Studio a nugetek cachelése miatt nem működik úgy, ahogy az elvárt lenne, abban az esetben lehetőségünk van a lokális cache-t üríteni.

GUI megoldás:
Tools → Options → NuGet Package Manager → Package manager settings → Clear All Nuget cache

CLI megoldás:
1. nuget.exe beszerzése – https://dist.nuget.org/win-x86-commandline/latest/nuget.exe
2. Parancs kiadása

nuget locals all -clear
