Solution:
In the ‘class’ word from the Foo class we had an odd character for Unicode world. The character named is ‘Zero with space’. Is like a space between words but without a visible space (width). Because Visual Studio can process also Unicode files, we have no limitation to add Unicode characters that are not visible using a normal editor. If we open the file with Total Commander viewer for example we will be able to see the character (in hex view for example).
Nice job :-)

  1. Hehe, simple one.

    When in doubt, retype the text. The problem is with the keyword "class". For example, if you put the cursor at the end of "class", and press CTRL+Left (that is, jump over one word), it will jump INSIDE the class, after the 'l' char.

    Looking at the source with a HEX Viewer we see:
    cl​ass . That is the ANSI representation. There is some UTF-8 garbage in there :)

    1. You are almost there. You need to tell me what is that character? What represents?

    2. U+200B

      Unicode line break:
      http://www.fileformat.info/info/unicode/char/200b/index.htm

      Probably from some weird editor/another operating system

    3. Nice - the file is UTF-16 encoded (big endian), that is ok.. Word has the habit to insert zero-width-spaces sometimes.. :)

  2. I think that the file is encoded in ANSI and the "a" character in "class" is "â" which isn't a latin character. The ANSI encoded file permits to use characters from other alphabets not only latins character.

  3. I added the solution to the post. Enjoy.

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…
