Code Contract does not work on Visual Studio 2017

I have an old project which uses Code Contract.

When I opened in Visual Studio 2017, it does not show the Code Contract link in the project properties.

"It shows an error message - An assembly must be rewritten using the code contracts binary rewriter (CCRrewrite) because it is calling

Contract.Requires<TException> and the CONTRACTS_FULL symbol is defined."

I installed Code Contract and still it is not working.

Any idea!

Thanks,
