我试图从命令行自动化我的构建。不幸的是，我的项目并不打算从一开始就被自动化，现在我正在努力与T4模板。TextTransform无效的转换错误
发现了几个错误后（this和this）尝试使用改造T4模板的MSBuild当我决定从我的项目的根目录找到所有的* .TT文件，并通过应用TextTransform给他们，一个一。
但是...其中一些有点问题。当那些运行TextTransform我收到以下消息：
C:\Specifications.tt(0,0) : error : Running transformation: System.InvalidCastException: Cannot convert 'Microsoft.VisualStudio.TextTemplating.CommandLine.CommandLineHost' into 'System.IServiceProvider'. en Microsoft.VisualStudio.TextTemplating7ea01e60423f49d2871739be33c0c810.GeneratedTextTransformation.GetProject() in Microsoft.VisualStudio.TextTemplating7ea01e60423f49d2871739be33c0c810.GeneratedTextTransformation.FindClasses(String nameSpace, String className, String baseClassName) in Microsoft.VisualStudio.TextTemplating7ea01e60423f49d2871739be33c0c810.GeneratedTextTransformation.TransformText()
打开.TT和寻找的IServiceProvider或CommandLineHost，我发现这两种方法：
private Project GetProject()
{
IServiceProvider serviceProvider = (IServiceProvider)this.Host;
DTE dte = serviceProvider.GetService(typeof(DTE)) as DTE;
// Get DTE
//var dte = (DTE)TransformationContext.Current.GetService(typeof(DTE));
// Get ProjectItem representing the template file
ProjectItem projectItem = dte.Solution.FindProjectItem(this.Host.TemplateFile);
// Get the Project of the template file
Project project = projectItem.ContainingProject;
return project;
}
private string GetDefaultNamespace()
{
IServiceProvider serviceProvider = (IServiceProvider)this.Host;
DTE dte = serviceProvider.GetService(typeof(DTE)) as DTE;
// Get DTE
//var dte = (DTE)TransformationContext.Current.GetService(typeof(DTE));
// Get ProjectItem representing the template file
ProjectItem projectItem = dte.Solution.FindProjectItem(this.Host.TemplateFile);
// Get the Project of the template file
Project project = projectItem.ContainingProject;
var vsSolution = (IVsSolution)serviceProvider.GetService(typeof(SVsSolution));
IVsHierarchy vsHierarchy;
ErrorHandler.ThrowOnFailure(vsSolution.GetProjectOfUniqueName(project.FullName, out vsHierarchy));
uint projectItemId;
ErrorHandler.ThrowOnFailure(vsHierarchy.ParseCanonicalName(projectItem.FileNames[1], out projectItemId));
object defaultNamespace;
ErrorHandler.ThrowOnFailure(vsHierarchy.GetProperty(projectItemId, (int)VsHierarchyPropID.DefaultNamespace, out defaultNamespace));
return ((string)defaultNamespace);
}
是否有可能解决此不知何故？更改.tt代码，使用替代方法...
我只是想从命令行自动化我的构建！

为什么不使用TFS构建服务器来自动构建？ – Kar
因为整个部署过程涉及多个更复杂的步骤。 – Luis
因为我们没有TFS。因为我想要一个简单，易于配置，灵活的机制，最好基于命令行。所以，TFS构建服务器在这里不是一个选项。 – Luis
