One option is that you can manually change the fragments that interest you. In Visual Sutio (I use 2013 Community Edition), go to Tools → Code Snippet Manager ... (or press Ctrl + K , Ctrl + B ). You will get a dialog with all the VS fragments using:

Select the fragment you want to change. For instance. for a loop in Visual C #. You will get the location of the fragment. You can edit it. For example, declaring a fragment of a for loop:
<Snippet> <Declarations> <Literal> <ID>index</ID> <Default>i</Default> <ToolTip>Index</ToolTip> </Literal> <Literal> <ID>max</ID> <Default>length</Default> <ToolTip>Max length</ToolTip> </Literal> </Declarations> <Code Language="csharp"><![CDATA[for (int $index$ = 0; $index$ < $max$; $index$++) { $selected$ $end$ }]]> </Code> </Snippet>
To get what you want, you need to replace for (int $index$ = 0; with for (Int32 $index$ = 0;
To change all the fragments is a laborious task, but I am sure that in most cases you can use the Notepad ++ search and replace function (if you correctly and accurately determine what needs to be replaced) to replace the aliases with the correct type names.
