I have setup.exe. This is a Basic MSI Installation package. I use InstallShield to create it. How can I get its FileVersion in MSBuild script? I cannot use GetAssemblyIdentity task 

    <GetAssemblyIdentity AssemblyFiles="setup.exe">
        <Output
            TaskParameter="Assemblies"
            ItemName="MyAssemblyIdentities"/>
    </GetAssemblyIdentity>

because my setup.exe is not an assembly and doesn't contain an assembly manifest, so an error appears if invoke this task:

Could not load file or assembly 'setup.exe' or one of its dependencies. The module was expected to contain an assembly manifest.

The FileVersionInfo class provides this functionality, and inline code allows using it from MSBuild directly:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" >

  <UsingTask TaskName="GetVersion" TaskFactory="CodeTaskFactory"
             AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll" >
    <ParameterGroup>
      <TheFile Required="true" ParameterType="System.String"/>
      <TheVersion ParameterType="System.String" Output="true" />
    </ParameterGroup>
    <Task>
      <Code Type="Fragment" Language="cs">
        <![CDATA[
          TheVersion = System.Diagnostics.FileVersionInfo.GetVersionInfo( TheFile ).FileVersion;
         ]]>
      </Code>
    </Task>
  </UsingTask>

  <Target Name="DoGetVersion">
    <GetVersion TheFile="$(MyAssemblyIdentities)">
      <Output PropertyName="FetchedVersion" TaskParameter="TheVersion" />  
    </GetVersion>
    <Message Text="Version = $(FetchedVersion)" />
  </Target>

</Project>

  • Can you explain this a bit more? – Stefan Vasiljevic Apr 02 '15 at 17:15
  • @StefanVasiljevic what exactly do you want to know? The GetVersion/CodeTaskFactory part is a way to make msbuild run C# code, calling GetVersionInfo in this case. DoGetVersion just calls GetVersion and siaplys the result. – stijn Apr 03 '15 at 07:10

    I figured it out. The problem was in the TheFile part. I actually forgot to replace that with the actual path to the file I want to get the version of. Thx :) – Stefan Vasiljevic Apr 04 '15 at 13:15
