5. Introduction to composite UI Application Block (CAB) Workspace

Through the previous introduction, we can know thatMainThe method is inherited fromFormshellapplicationObject instances can perform initialization of many frameworks, such as loading modules and loading services. SlaveFormshellapplicationType Definition:

Public abstract class formshellapplication <tworkitem, tshell>:Windowsformsapplication<Tworkitem, tshell> where tworkitem:WorkitemWhere tshell: Form

We can see that two types of parameters are required, one isWorkitem, One isForm,FormshellapplicationThe two types are instantiated during initialization. AndFormType instanceShow. HereFormThe type of instance is our applicationProgram.
