t4

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. <#@ template language="C#" hostspecific="True" debug="True" #> <#@ output extension="cs" #> <#@ assembly name="System.Core.dll" #> <#@ assembly name="$(TargetDir)\MyDependency.dll" #> This works in Visual Studio, I have a VS Macro which defines $(TargetDir) correctly. Now, I want to perform the code generation process during my build process. I added: <TransformOnBuild>true</TransformOnBuild> <OverwriteReadOnlyOutputFiles>true<

Is it possible to make a T4 template output to be merged with an existing file? For example, if a T4 template generates localization resource XML files, is it possible to merge them in some existing resource file? You can get access to the underlying string builder the the T4 uses thought the GenerationEnvironment property. So by adding something like the following to your T4 you should be able to get a workable solution; <#@ template debug="false" hostspecific="false" language="C#" #> <#@ output extension=".txt" #> <#@ Import Namespace="System.IO" #> Line #<#= rand.Next(0, 100).ToString() #>

The question is: is there a way to have a setting in the *.tt file so that the generated files are set to a specified Build Action? The thing is I am generating SQL script using a template. I use this script as pre-deploy script in Database project. Currently, I have to manually set the Build Action to Pre-Deploy every time a file being re-generated - I would like to automate it. Both files - template and SQL that it generates - are included into project. In Project (*.sqlproj) they are as next tags: <PreDeploy Include="Migration\PreDeployScript.sql"> <DependentUpon>Migration\PreDeployScript

I would like to analyse a DLL from within a T4 template using Reflection, so that I can generate code based on the results of the reflection analysis. I know EnvDTE would be a better option, but this is not possible in my case for several reasons. The problem with reflection is that the DLL is a 64-bit DLL and if I load that within the T4 template I get a BadImageFormatException because I am trying to load a 64-bit DLL into a 32-bit process (Visual Studio 2012). Is there any way to analyse the contents of that DLL within T4, preferrably using reflection? I have already thought about writing a

I like to to keep my code first - or T4 generated - POCOs in a project separated from the DbContext. This helps me ensure my entity classes aren't coupled to any one data access service. When I create a new DB first EDMX model, the wizard generates a T4 template to generate all the POCOs in the same project as the DbContext. How can I modify this template to add classes to a separate project? On closer inspection, it would probably be much easier to move the DbContext to a new project, but the T4 for this has no call to fileManager.StartNewFile so i don't know where to begin telling it to

NOTE: I am using ASP.Net application and not MVC [so no validation attribute are supported] I used Database First approach and then generated my POCO classes using the POCO t4 template. I moved the generated POCO classes in it's own library (Domain.Model). Now I want to inject validation to the POCO class using Enterprise Library 5. How can I do that. I don't want to perform validation in UI, but want to add the validation attributes using Enterprise Library to the POCO class without modifying the generated POCO class. If I modify it, then whenever I generate new classes, I will loose all my

I have some T4 include files which I want to reuse in several projects. So I have created a NuGet package and placed the files in the Tools folder of the package. Now they are installed in the packages\PackageName.x.x.x\Tools folder and I can add an include directive in my T4 files in the project. But the disadvantage of this is, that there is a version number in the path which will change when I create new versions of the package. That would require me to update all include directives in the project. Does anybody know a hint for a good approach for this? If these T4 templates are supposed to
