Visual Studio, Xamarin and Debug an APP

While developing an iOS-App with Visual Studio and Xamarin you may get this message:

Visual Studio cannot start the application automatically because
it was signed with a Distribution provisioning profile. Please start it
by tapping the application icon on the device

Boom! And you are not able to debug you App. But hold on … there is a fix.

First of all ensure that have you selected the correct Singing Identity in you iOS project setting iOS Bundle Signing. It should be Developer (Automatic) and Provisioning Profile should be Automatic as well.

Then check you Certificates and Provisioning Profiles in you Apple Developer Console. Ensure that you have a correct Identifier App ID! And the most important thing … Ensure there is a Development Provisioning Profile which includes the App ID. You can use a wild card or explict one.

Then download the profile, import it to you Mac OS and clean you build. Now it should work!

Dictionary with foreach

I’ve just want to mention how to do a foreach with a .NET 2.0 Hashtable:

[sourcecode lang=“c#“]Dictionary< string, int > dict = new Dictionary< string, int >();
dict[„one“] = 1;
dict[„two“] = 2;
dict[„thress“] = 3;

foreach( KeyValuePair< string, int > data in dict)
{
Debug.WriteLine( data.Key + “ => “ + data.Value );
}[/sourcecode] So this time KeyValuePair is our friend.
