Change only Revision number in AssemblyInfo.cs with MSBuild FileUpdate task

msbuild, msbuild-task

Solution

How about this:

<FileUpdate Files="Properties/AssemblyInfo.cs"
   Regex="(\d+)\.(\d+)\.(\d+)\.(\d+)"
   ReplacementText="$1.$2.$3.$(Revision)" />

Problem

I need to change only the revision number of an `AssemblyInfo.cs` file. The version number is in the format Major.Minor.Build.Revision e.g. `1.4.6.0`. Currently I change the version with the `FileUpdate` task (from the MSBuild Community Tasks Project) and the following regex: ``` <FileUpdate Files="@(AssemblyResult)" Regex='(\[\s*assembly:\s*AssemblyVersion\(\s*"[^\.]+\.[^\.]+)\.([^\.]+)(\.)([^\.]+)("\)\s*\])' ReplacementText='[assembly: AssemblyVersion("$(AssemblyMajorNumber).$(AssemblyMinorNumber).$(AssemblyBuildNumber).$(Revision)")]' /> ``` Now I need to update only the revision number and leave major,minor and build unchanged. So, is there any task to do this? Or can it be done with a regex? What would be the regular expression then?
