Question

I believe my problem occurs when using Nuget, however, if you are reading because of the TF30063 error. Have a look at the answer I provided and accepted.

Original Post

I am getting this error message when I try to check out. This happens randomly and can occur even if minutes ago the same instance of visual studio allowed me to check something else out for edit.

The current workaround is to reopen VS2010.

Using W7x64, vs2010 ultimate with TF2010 and sql2008 on my local dev machine. I am not part of a domain. I am the administrator of this computer.

When the problem occurrs, I "close solution" under file. And then reopen the solution. I then get a uid/pwd box. I put my admin uid/pwd into it and then get a further error message. Again, closing vs2010 and reopening solves the issue.

I believe this has to do with nuget. I have provided an answer and so far after many months I have not had a TFS error. Where I should have had an error given the types of operations I have been performing which were identical to the scenarios making it fail.

Answer 1

I noticed that the problem occurred mostly after i installed a nuget package. After adding a nuget package i found that I could not check out. Restarting Visual Studio helped.

Based on this discussion:

i used this solution which appears to be working:
(I have copied the solution here if ever the webpage disappears)

Control Panel / Internet Options / Security Tab
Select "Local Intranet"
Click Sites button
Click Advanced Button
Add your TFS server http address to the list. e.g. http://tfs
Restart Visual Studio

Don't let the Internet Options part fool you. I do not use Internet Explorer and this solved my issue.
