Process Macro variables into T4 TextTemplate RRS feed

  • Question

  • I've a problem when I try to invoke the text transformation in a VSExtension.

    // Get the text template service: 

    ITextTemplating t4 = serviceProvider.GetService(typeof(STextTemplating))  as ITextTemplating;

    var vsHostEngine = t4 as ITextTemplatingEngineHost;

    ITextTemplatingSessionHost sessionHost = t4 as ITextTemplatingSessionHost;

    sessionHost.Session = sessionHost.CreateSession();

    sessionHost.Session["Rigenerate"] = parameter;

    TemplateCallBack templateCallBack = new TemplateCallBack();

    // Process a text template: 

    string result = t4.ProcessTemplate(templateFullFilePath, templateContent, templateCallBack)


    When I Call t4.ProcessTemplate(....) the template engine don't process the macro variables $(SolutionDir) (for example) and this issue generate in a template process error.

    My Question is: how I can I do to resolve the MacroVariables?

  • Hi DavideSattin,

    According to your description, it seems that you want to retrieve macro variables value. If it is the case. I think that Project class could achieve it.  like this:

    string webPath = @"D:\Project\Data\WebApp\WebFormApp\WebFormApp.csproj";
    var webp = new Project(webPath);
    var test = webp.GetPropertyValue("Configuration");

    Please add reference Microsoft.Build

    Best regards,
