I'm running an Azure SQL Server and have some issues with the WebApi application which is using it. At some point under heavy load, the app starts to create lots of connections and sp_who2 shows that I have several long locks. After following the chain of locks I can see that the culprit is a sleeping connection which executes nothing at the moment (status = 'sleeping' and BlkBy = '.').
When I do a memory dump of the WebApi process, I can see that most of them have the following call stack:

All the blocked/blocking sessions are regular updates which are really fast and coudln't not delay a database call from the client side. I'm using EF6 and using(var db = new DB()) {...} for every db call.
What could be possibly wrong with the sleeping connection which blocks others? How can I debug the issue?
Ran into this issue just today! Ours is a web application, same as your situation, and the web app was incorrectly leaving a transaction open after finishing a request. Then it would just sit there waiting for the next request while it had the database locked.
Two things to check in the SQL code which might cause this problem are:
(1) Make sure that all of your BEGIN TRANSACTION statements have a corresponding COMMIT TRANSACTION at the end. Otherwise your app might incorrectly hold a transaction open while waiting for the next user request.
(2) Check all uses of THROW to see whether any THROW statements are inside of a transaction. If you want to throw an error during a transaction, you first have to ROLLBACK TRANSACTION before the THROW, or else SQL Server will leave the transaction open and the database locked.

I have problem with using WCF WSDualHttpBinding only in WPF application. Before changes this WCF worked. Now not working. I changed only ServiceBehaviour (ConcurrencyMode and InstanceContextMode) to:
[ServiceBehavior(IncludeExceptionDetailInFaults = true, ConcurrencyMode = ConcurrencyMode.Reentrant, InstanceContextMode = InstanceContextMode.PerSession)]
After that, WCF not responding, see exception detail. Any ideas?

Looks like your WCF call is timing out because you have set your WCF server (to essentially) Single access. If you have multiple calls to the service at the same time, your WCF service processes them one at a time, and with your very short timeout, its not surprising that some of them timeout.
Could you explain WHY you changed your ConcurrencyMode?
I don't know how, but problem was resolved after time. I think problem was in missing updates.

When I run Update-Database from within Visual Studio everything works fine, so I know the migrations themselves are working.
This is on a SQL Server database.
I just ran into this today. This can happen when you used the wrong sets of DLL when you run migrate.exe.
In my case, I used the .Net 4.5 version in migrate.exe but compiled my project using .Net 4.0's version.
After changing the dlls the problem went away.
I'm not sure if this has been posted before, but I can't find an answer.
I started a new job and when I start up this wpf project I get this error as the inner exception:
{"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."}
There are several suggestion on adding an exception for visual studio 2008, but I'm running 2010. Does anyone know what next steps I should take to resolve the issue?

Exploring the inner stack trace led me to a connection / trust issue regarding one of the services. Place a breakpoint at the top of the MainWindow and step through. Errors like this often confuse me the most. Don't give up, just step through and ask for help.
Sometimes my XBAP application gives this error. Did someone else had this problem?

This error stopped happening they release the final stable .Net Framework 4.0 .
This was problably caused by some bug in the Beta that I was using.
