A handler signature verifier for command methods with seven generic parameters. It validates a MethodDescription by attempting to create a closed delegate of either Func<T1,...,T7, CommandResult> or Func<T1,...,T7, Task<CommandResult>> depending on the method return type, without invoking the delegate.

public void Validate( Sandbox.MethodDescription method )
{
if ( method.ReturnType == typeof( CommandResult ) )
{
_ = method.CreateDelegate<Func<T1, T2, T3, T4, T5, T6, T7, CommandResult>>();
}
else
{
_ = method.CreateDelegate<Func<T1, T2, T3, T4, T5, T6, T7, Task<CommandResult>>>();
}
