Nikolay Izhikov commented on IGNITE-6055:
-----------------------------------------

> 5) I do not see how compatibility is handled in .NET - new fields are serialized unconditionally, meaning that we cannot talk to previous version. Am I wrong?

Fixed.
Now, all your comments are fixed.

Please, review PR.

> We should support {{CHAR(X)}} and {{VARCHAR{X}} syntax. Currently, we ignore it. First, it affects semantics. E.g., one can insert a string with greater length into a cache/table without any problems. Second, it limits efficiency of our default configuration. E.g., index inline cannot be applied to {{String}} data type as we cannot guess it's length.
