Function registerDebugConfigurationProvider

Register a debug configuration provider for a specific debug type. The optional triggerKind can be used to specify when the provideDebugConfigurations method of the provider is triggered. Currently there are two situations: (1) providing debug configurations to populate a newly created launch.json (2) providing dynamically generated configurations when the user asks for them through the UI (e.g. via the "Select and Start Debugging" command). Please note that the triggerKind argument only applies to the provideDebugConfigurations method, the resolveDebugConfiguration methods are not affected at all. Registering a single provider with resolve methods for different trigger kinds results in the same resolve methods being called multiple times. More than one provider can be registered for the same type.
