❔ Infer the second generic type from input data

I am wondering if its possible to write the following code in some way that it works like I want it to. My goal is to specify a class and an argument. The function should then create the class and pass the argument to it.

Execute<MyValidator0>(someData0);  // Does not work, any way to change it so I can call it like this?
Execute<MyValidator1, MyDataType>(someData1);  // Works


void Execute<V, Arg>(Arg argument) where V:IValidator<Arg>, new()
{
    var instance = new V();
    instance.ValidateAndThrow(argument);
}

Execute<MyValidator0>(someData0);  // Does not work, any way to change it so I can call it like this?
Execute<MyValidator1, MyDataType>(someData1);  // Works


void Execute<V, Arg>(Arg argument) where V:IValidator<Arg>, new()
{
    var instance = new V();
    instance.ValidateAndThrow(argument);
}

ur method can only accept 2 generic arguments, create another one that accepts a single generic argument

How would one do that when the first generic arguemtn requires the second? void Execute<v<arg>>(arg argument) is not valid from my understanding

is there a reason u dont want to pass the 2nd generic argument?

Partly to make it look neater, but I am also really curious if its possible
