I'd like to use unity container to implement a singleton design.

for example:

create the singleton:

container.RegistryInstance<IClass>(new Class())

get the singleton instance:

container.Resolve<IClass>()

Can I do the same but with a class and not with interface?

for example:

create the singleton:

container.RegistryInstance<Class>(new Class())

get the singleton:

container.Resolve<Class>()
unity-container c#

Sure. In that case, you do not need to provide a type argument to RegistryInstance.

From http://unitycontainer.org/tutorials/registration/instance.html:

The simplest instance registration does not require any additional parameters other than instance itself:

var instance = new Service();

container.RegisterInstance(instance);

Resolving type Service like this container.Resolve<Service>() will return an instance of the Service object we registered.
