Visual Studio Online - Cannot add a new account (401, 403, TF400813)

In this post we will see what we need to do when we want to add a new user on our Visual Studio Online project, but we end up with errors like
  • 401
  • 403
  • TF400813
Let's start from the assumption that we are the administrator on VS Online. We added a user a few days ago on our project, with the same rights like other users. Even if we added the user, he is not able to access our project. It is well known that sometimes we need to wait a few hours until the rights and changes are propagated, but it never takes more than 12-24h.
In this moment we need to ask yourself what is different. There are times when the change propagation freeze and you need to remove and add the user again. We sad that this might be possible and let's remove the user and add him again to VS Online and to our project.
After removing the user we observed that we cannot find anymore the given account, even if it was a LIVE account. This was strange and odd. We remembered that a few days ago we had a similar issue ( because the integration between Azure AD and company AD.
We added the LIVE account to our AD as member. After this we added again the user to VS Online and project group.
New-MsolUser -UserPrincipalName -DisplayName "User A B" -FirstName "User A" -LastName "B"
Set-MsolUser -UserPrincipalName -UserType Member

Surprise, everything works as expected. The lesson learn is to double check the users in AD especially when under that subscription you have integration between on-premises AD and Azure AD.
Below you can find an MSND link where you can find the list of PowerShell comands that can be used in situations like this.

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 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…
