TFS2015: Offline - Sequence contains no elements

Hi Tim,

Since version 2.7.0 I cannot connect to our local TFS on prem anymore.

I keep seeing this error message:

Offline

Sequence contains no elements

 

Sometimes a restart of the app fixes it temporarily. But then all of a sudden, boom, same error again.

I was hoping this bug had been fixed in v 2.7.1 but unfortunately it isn't.

 

Hope you can fix this since we really rely on Catlight nowadays :) (And we're paid customers... ;)

This is fixed in 2.7.2. Empty projects should no longer cause errors like that.

Found the reason through the log files :)

Thanks for reporting this problem!

As far as I understand, the workaround that you found helped.

We are working on a fix for this.
