Add BuildNumber in GitTemplate.12.xaml - tfs

Question

In the related TfvcTemplate.12.xaml the solution is to add the build number like so:
<mtbwa:MSBuild CommandLineArguments="[String.Format("/p:SkipInvalidConfigurations=true
/p:BuildNumber={1} {0}", MSBuildArguments, BuildDetail.BuildNumber)]"
In the Git template the arguments have slightly changed, but doing the same results in the following error
Compiler error(s) encountered processing expression
"String.Format("/p:SkipInvalidConfigurations=true /p:BuildNumber={1} {0}",
AdvancedBuildSettings.GetValue(Of String)("MSBuildArguments", String.Empty),
BuildDetail.BuildNumber)".
'Microsoft.TeamFoundation.Build.Client.BuildDetail' is not accessible in
this context because it is 'Friend'.
What is the correct way to expose the BuildNumber in this template?

Answer 1

There's two steps I had to go through to make this work.

Within the same template you modified in step 1 click on the "Run MSBuild" activity, view properties and open "CommandLineArguments". I'm using OctoPack for Octopus Deploy so here's what my arguments look like:
String.Format("/p:SkipInvalidConfigurations=true /p:BuildNumber={1} {0}
/p:OctoPackPackageVersion={1}", AdvancedBuildSettings.GetValue(Of
String)("MSBuildArguments", String.Empty), BuildDetail.BuildNumber)
As you can see, BuildNumber is specified there so you can just remove the Octopus property I added. Finally within your msbuild file (.csproj for example) you'd use build number like so $(BuildNumber)
