  1. POT4 code generation during build, custom assembly reference
    text
    copied!<p>I have a T4 template that processes several .tt files in my project. I also have some custom classes I've defined to help with the code transformation process.</p> <pre><code>&lt;#@ template language="C#" hostspecific="True" debug="True" #&gt; &lt;#@ output extension="cs" #&gt; &lt;#@ assembly name="System.Core.dll" #&gt; &lt;#@ assembly name="$(TargetDir)\MyDependency.dll" #&gt; </code></pre> <p>This works in Visual Studio, I have a VS Macro which defines $(TargetDir) correctly.</p> <p>Now, I want to perform the code generation process during my build process. I added:</p> <pre><code>&lt;TransformOnBuild&gt;true&lt;/TransformOnBuild&gt; &lt;OverwriteReadOnlyOutputFiles&gt;true&lt;/OverwriteReadOnlyOutputFiles&gt; &lt;IncludeDslT4Settings&gt;true&lt;/IncludeDslT4Settings&gt; &lt;ItemGroup&gt; &lt;T4ReferencePath Include="$(OutputPath)" /&gt; &lt;/ItemGroup&gt; &lt;Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\TextTemplating\v10.0\Microsoft.TextTemplating.targets" /&gt; </code></pre> <p>My build runs, but I get:</p> <blockquote> <p>C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\TextTemplating\v10.0\Microsoft.TextTemplating.targets (407): The host threw an exception while trying to resolve the assembly reference '$(TargetDir)\MyDependency.dll'. The transformation will not be run. The following Exception was thrown: System.IO.FileLoadException: The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) at System.Reflection.AssemblyName.nInit(RuntimeAssembly&amp; assembly, Boolean forIntrospection, Boolean raiseResolveEvent) at System.Reflection.AssemblyName.nInit() at Microsoft.VisualStudio.TextTemplating.GlobalAssemblyCacheHelper.GetLocation(String strongName) at Microsoft.VisualStudio.TextTemplating.Sdk.Host.GenericTextTemplatingHost.ResolveAssemblyReference(String assemblyReference) at Microsoft.VisualStudio.TextTemplating.Engine.ResolveAssemblyReferences(ITextTemplatingEngineHost host, TemplateProcessingSession session). Line=-1, Column=-1</p> </blockquote> <p>Obviously it won't resolve <code>$(TargetDir)</code> in Team build context.</p> <p>I tried adding TargetDir to my build configuration's property group, to no avail. This value doens't pass through to the context of the T4 Code Generator.</p> <p>I don't want to use an environment variable.</p> <p>How can I set <code>$(TargetDir)</code> correctly in Team Build context?</p>
