Remarks

You should use this method to avoid caching information in variables.

The method gets the class cache that is associated with the validation context. When this method is called for the first time, a cache is created for the class. Each additional time this method is called, the existing cache is retrieved. A cache is created for each parameter class and can be called from other classes.

To use this method, the target class must have a zero-parameter constructor. Composite classes are also allowed. For example, you could use: context.GetCache<Dictionary<string, extraObject>>()

After the cache is returned, you can use it with the ValidationMessageObserver class, which enables you to pass information between validation methods.
