Question

I want to create an instance of any class using generics.
Is that possible?

I tried this but doesnt work:

public class blabla 
{
    public void bla();
}
public class Foo<T>
{
    Dictionary<string, Func<object>> factory;

    public Foo() => factory = new Dictionary<string, Func<object>>();
    public WrapMe(string key) => factory.Add(key, () => new T());
}

...

var foo = new Foo<blabla>();
foo.Wrapme("myBlabla");

var instance = foo.factory["myBlabla"];
instance.Bla();

You only need a method:

private static T InstantiateInstance<T>() where T : new() => new T();
