Symptoms
Microsoft Visual Studio 2015 Release Candidate (RC) repeatedly prompts you to enter your user credentials when you sign in to the program or when you access different features in Visual Studio. This can occur immediately after you successfully enter the correct credentials for a Microsoft account or for a work or school account. This issue can also occur intermittently when you access different features in Visual Studio.
Cause
This issue has two separate causes.
Cause 1
Version 2.11 of the Azure Active Directory Authentication Library (ADAL) is not setting the internal IsMultipleResourceRefreshToken flag correctly for tokens that are associated with a Microsoft account.
Cause 2
The Internet Explorer session count may decrement to zero (0) during the process to acquire tokens that are required to access resources in Visual Studio.
