Store MyGet credentials in your roaming user profile NuGet.config

register a myget feed.markdown

Execute the following script using your MyGet [feedUrl] and MyGet [username] , [password] and [apikey]. Run this from a commandline where you have access to nuget.exe (or set the path to your nuget.exe in a system environment variable).

Store credentials in machine-level nuget.config (non-transferable)

nuget setapikey [apikey] -source [feedUrl]
nuget sources add|update -Name [name] -source [feedUrl] -User [username] -pass [password]

Store credentials in specific nuget.config (non-transferable)

nuget setapikey [apikey] -source [feedUrl] -configFile [configFilePath]
nuget sources add|update -Name [name] -source [feedUrl] -User [username] -pass [password] -configFile [configFilePath]

Store credentials in specific nuget.config (transferable)

Don't bother putting the above nuget.config files into source control as they'll only work on the machine and the account that created the configs.

To be able to share credentials, use the -StorePasswordInClearText option:

nuget setapikey [apikey] -source [feedUrl] -configFile [configFilePath]
nuget sources add|update -Name [name] -source [feedUrl] -User [username] -pass [password] -configFile [configFilePath] -StorePasswordInClearText

Sorry, for over complicating, but I'm not to familiar with the github gist / git fork / pull request issues yet, but I have a small fix for your gist here:
https://gist.github.com/paumayr/8845667

Hi @paumayr, you can click the fork button on top of this page, make changes to your fork, and submit a PR, should be easy :) Otherwise, would you mind highlighting what changes you did?
Thanks!

This is what exactly I need, thank you xavierdecoster:) One thing I know that after you store the myget credential in the global NuGet.Config file and the window asking your password still prompt up. You could try Run as administrator when open your Visual Studio

I'm trying this solution to work around the bug in TeamCity/Nuget around the authenticated feed but it still doesn't seem to be working. What is the right directory to put the nuget.config file in? Is it case sensitive (NuGet.config vs nuget.config)? does the source URL need to match the "internal"/localhost url of the feed? trailing / or no trailing /?

so many questions!
