Passing Type variable as Generic Type Parameter to Static Class

I have the following static class

public static class MyFoo<T> where T : class
{
    public static IBar<T> Begin()
    {
        return new Bar<T>();
    }
}

Elsewhere, I have a variable of System.Type, which I need to pass in as the Generic Type argument, ideally:

public void MyFunction(Type type)
{
     MyFoo<type>.Begin();
}

I know its possible through reflection to return an instance of MyFoo (If i make it non static) but this would not be ideal. Is there anyway to pass type as a Generic Type argument to the MyFoo static class?

Can't do it. The value of the type variable in the second sample is only known at run time. The T type parameter in the first sample must be resolved at compile time.

Instead, look into Activator.CreateInstance().
