I have C# web service project called MyService.csproj. In MyService.asmx.cs I have a description field:

[WebService(Description="My Web Service")]

I want to change this field to include a version number before I compile the solution that contains the project so it will look something like this:

[WebService(Description="My Web Service v1.0")]

I'm completely new to regular expressions and have tried unsuccessfully to use them in "Replace In File" without success.

Expression to find:
[[WebService(Description="My Web Service ?")]]

Replace matches with:
[[WebService(Description="My Web Service %FILE_VERSION%")]]

This doesn't work. Any ideas?
