I have a lecture next week on performance and developers tools and I went to an old project (TicTacToe – Created in VS 2010 ) I’m using to demonstrate code analysis.

Windows Azure Storage Emulator – v3.0 – Installation failed

01/07/2014

Today I faced a very annoying and strange issue while installing newer version of Azure Storage Emulator on my machine. Tried to remove almost everything related to Azure but still nothing worked…. Although I ran DsInit to work on SQLEXPRESS instead of localdb I decide to delete sql local db by running the following commands: sqllocaldb stop v11.0 sqllocaldb delete v11.0 sqllocaldb create v11.0” The result should be - “LocalDB instance "v11.0" created with version 11.0.” After recreating SQL local db Azure Storage Emnulator worked. Hope this helped.

Control\Reduce TFS DB Size

29/06/2014

Today I received an email from the company DBA saying that out TFS Backup failed because “There is not enough space on the disk”. First I’ve opened SSMS to understand how big is our TFS DB and I…….. What????? I knew that we’re getting bigger from day to day (more and more groups are joining to start working with TFS) but 633GB??? TFS DB Size growth usually comes from Attachments and Source Control, So I tried to understand which Team Projects are taking most of the space. I need to understand what type of attachments are taking all that space, again per...

Could not establish trust relationship for SSL/TLS secure channel

26/06/2014

Working with WebClient to fetch some data from a web service (HTTPS) return an error, now it’s fully understandable why this exception raised – the server certificate has expired and isn’t valid any more. But how I can still getting the data from the service although the certificate isn’t valid??? You just need to override the ServerCertificateValidationCallback property - Gets or sets the callback to validate a server certificate. System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; And you’re done!

How To: Run Tests On Different Machines In Parallel

18/06/2014

I’m getting this question a lot, how to run multiple tests on different machines in parallel? Every customer that I work with has over 100 tests and some has more than 1000+. So how to improve test execution time? running 1000+ tests can take a while and we want to get the results as fast as possible. So, for Unit Tests there is a nice trick (Wrote about it in 2010 –>Run Unit Tests in Parallel using Visual Studio 2010) that allow you to run those tests in parallel on the same machine. But what about Coded UI Tests? you most know we...
