Dialog for adding properties is quite complex now and user can simply make a mistake when using it, generating an
invalid code in the editor.

An example could be generating a property of type String called S and assigning a value of '5' to it (int property).
User gets no warning, no errors are shown in the preview, but when he/she clicks OK, erroneous code is generated in the
editor. Another example is assigning a scalar value to indexed property...

Implementing various individual checks for fields in this dialog is infeasible and it would be a long term run -
therefore I believe that solution using infrastructure what we already have should be a better way to go.

It would be helpful to disable OK button in case that code would contain new errors if property was generated with
currently given parameters. There would be also a warning in the bottom of the dialog describing the problem, like
"Generated code would contain errors - review property parameters and fix all problems". (Maybe disabling OK button is
too much, a warning could be enough...).

A compiler that we use can be easily used for this check - you can for example just place the code that is displayed in
the preview to some fake empty class and try to compile it...
