Testing App on Windows Phone

Question

I have unlocked my Nokia Lumia phone for development.
1. I would like to know if I can test my app on my phone for any longer or is it restricted to some time period like 30 days. (I have not paid $19,as I am not planning on publishing the app as of now)
2. Also is there any restriction on the number of apps that I can test on the same phone with the same id.

Answer 1

Since you don't have developer account you can deploy app for limited time and you can deploy max 3 apps at once. If you have developer account then time period increases and you can deploy 10 apps at once.

A Microsoft account

How do I sign up for a Microsoft account?

•Optionally, a valid and current developer account on Windows Phone Dev Center

If you have a developer account, you can register three devices to use for app development, and you can publish apps in the Windows Phone Store.

If you don’t have a developer account, you can only register one device to use for app development. Before you can publish apps in the Windows Phone Store, you have to register.
