## Constructors

- [Ulimit](/reference/api/csharp/aspire.hosting.docker/ulimit/constructors.md#constructor)

## Properties

- [Hard](/reference/api/csharp/aspire.hosting.docker/ulimit/properties.md#hard) : `int?` `get; set` -- Gets or sets the hard limit for the resource control.
- [Soft](/reference/api/csharp/aspire.hosting.docker/ulimit/properties.md#soft) : `int?` `get; set` -- Defines the soft limit for the Ulimit configuration. The soft limit is the value for resource restrictions that a process is allowed to increase up to the hard limit. This property is nullable, which indicates that this configuration might not be set.
