void	DeployClusterSingleton (string name, IService service)
	Deploys a cluster-wide singleton service. Ignite guarantees that there is always one instance of the service in the cluster. In case if Ignite node on which the service was deployed crashes or stops, Ignite will automatically redeploy it on another node. However, if the node on which the service is deployed remains in topology, then the service will always be deployed on that node only, regardless of topology changes. More...

Task	DeployClusterSingletonAsync (string name, IService service)
	Deploys a cluster-wide singleton service. Ignite guarantees that there is always one instance of the service in the cluster. In case if Ignite node on which the service was deployed crashes or stops, Ignite will automatically redeploy it on another node. However, if the node on which the service is deployed remains in topology, then the service will always be deployed on that node only, regardless of topology changes. More...

void	DeployNodeSingleton (string name, IService service)
	Deploys a per-node singleton service. Ignite guarantees that there is always one instance of the service running on each node. Whenever new nodes are started within the underlying cluster group, Ignite will automatically deploy one instance of the service on every new node. More...

Task	DeployNodeSingletonAsync (string name, IService service)
	Deploys a per-node singleton service. Ignite guarantees that there is always one instance of the service running on each node. Whenever new nodes are started within the underlying cluster group, Ignite will automatically deploy one instance of the service on every new node. More...

void	DeployKeyAffinitySingleton< TK > (string name, IService service, string cacheName, TK affinityKey)
	Deploys one instance of this service on the primary node for a given affinity key. Whenever topology changes and primary node assignment changes, Ignite will always make sure that the service is undeployed on the previous primary node and deployed on the new primary node. More...

Task	DeployKeyAffinitySingletonAsync< TK > (string name, IService service, string cacheName, TK affinityKey)
	Deploys one instance of this service on the primary node for a given affinity key. Whenever topology changes and primary node assignment changes, Ignite will always make sure that the service is undeployed on the previous primary node and deployed on the new primary node. More...

void	DeployMultiple (string name, IService service, int totalCount, int maxPerNodeCount)
	Deploys multiple instances of the service on the grid. Ignite will deploy a maximum amount of services equal to totalCount parameter making sure that there are no more than maxPerNodeCount service instances running on each node. Whenever topology changes, Ignite will automatically rebalance the deployed services within cluster to make sure that each node will end up with about equal number of deployed instances whenever possible. More...

Task	DeployMultipleAsync (string name, IService service, int totalCount, int maxPerNodeCount)
	Deploys multiple instances of the service on the grid. Ignite will deploy a maximum amount of services equal to totalCount parameter making sure that there are no more than maxPerNodeCount service instances running on each node. Whenever topology changes, Ignite will automatically rebalance the deployed services within cluster to make sure that each node will end up with about equal number of deployed instances whenever possible.

void	Deploy (ServiceConfiguration configuration)
	Deploys instances of the service in the Ignite according to provided configuration. More...

Task	DeployAsync (ServiceConfiguration configuration)
	Deploys instances of the service in the Ignite according to provided configuration. More...

void	Cancel (string name)
	Cancels service deployment. If a service with specified name was deployed on the grid, then IService.Cancel method will be called on it. Note that Ignite cannot guarantee that the service exits from IService.Execute method whenever IService.Cancel is called. It is up to the user to make sure that the service code properly reacts to cancellations. More...

Task	CancelAsync (string name)
	Cancels service deployment. If a service with specified name was deployed on the grid, then IService.Cancel method will be called on it. Note that Ignite cannot guarantee that the service exits from IService.Execute method whenever IService.Cancel is called. It is up to the user to make sure that the service code properly reacts to cancellations. More...

void	CancelAll ()
	Cancels all deployed services. Note that depending on user logic, it may still take extra time for a service to finish execution, even after it was cancelled. More...

Task	CancelAllAsync ()
	Cancels all deployed services. Note that depending on user logic, it may still take extra time for a service to finish execution, even after it was cancelled. More...

	Gets metadata about all deployed services. More...

T	GetService< T > (string name)
	Gets deployed service with specified name. More...

ICollection< T >	GetServices< T > (string name)
	Gets all deployed services with specified name. More...

T	GetServiceProxy< T > (string name)
	Gets a remote handle on the service. If service is available locally, then local instance is returned, otherwise, a remote proxy is dynamically created and provided for the specified service. More...

	Gets a remote handle on the service. If service is available locally, then local instance is returned, otherwise, a remote proxy is dynamically created and provided for the specified service. More...
