A host application installs and runs Intel® DAL trusted applications on the internal platform firmware and provides the user experience to the external world. Host applications can be developed in the basic host application template created by the Intel DAL project wizard on request or in the IDE of your choice provided you adhere to the basic host application requirements of Intel DAL host applications. Intel DAL supports host application development in C++, C# and .NET*.

Host applications are debugged in the program they are developed in, e.g., Microsoft Visual Studio*, using standard code debugging procedures. When we discuss debugging in the SDK, we refer to debugging a trusted application via the host application.

Development in a Windows* environment is fully supported by the SDK. For Android development, the SDK provides additional tools which must be run independently on an Android OS. For details on these tools, see Generic Android Host Application.

Trusted application development is the same for Windows and Android platforms and can be done using the core SDK environment. Host application development differs between Windows and Android.
