.Net framework data type change breaking code across application

In one of our application developed in .net framework, there was change in datatype of the column across multiple table from int to long/bigint.

This started breaking application code across multiple places. This is due to - 

• Inline query still trying to fetch Int data type whereas datatype changed to Long/BigInt
• Biding Int data to controls are breaking
• Boxing/Unboxing could be the reason

Current solution is to manually search and change datatype across all the modules/components in application. But this is time consuming and manual work.

Can ReSharper tool help in any way to speed-up fixing this issue for identification and fixing datatype change across the application code. Please suggest if there is any other approach to make it faster and automated.
