You can do this also through MSBuild using the GetAssemblyIdentity task :
<GetAssemblyIdentity
AssemblyFiles="$(MSBuildProjectDirectory)\src\MyApp\bin\MyApp.exe">
<Output
TaskParameter="Assemblies"
ItemName="AssemblyIdentities"/>
</GetAssemblyIdentity>
And then rename your .exe file:
<Copy
SourceFiles="$(MSBuildProjectDirectory)\src\MyApp\bin\MyApp.exe"
DestinationFiles="$(MSBuildProjectDirectory)\src\MyApp\bin\MyApp-(AssemblyIdentities.Version).exe"></Copy>
<Delete
Files="$(MSBuildProjectDirectory)\src\MyApp\bin\MyApp.exe"></Delete>
