To account for this the .targets file has been modified to use the generated config file instead of the version in source. The generated file can be text of any kind, such as a web page, or a resource file, or program source code in any language. I am trying to modify the List.cs.t4 template located C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\Extensions\Microsoft\Web\Mvc\Scaffolding\Templates\MvcView by placing in the CodeTemplates\MvcView folder within the project, but it is not being used when … Alternatively, you can add a plain text file and set its Custom Tool property to TextTemplatingFileGenerator.

If you are building .NET Core applications then realize that XML-based configs are out and JSON files (options) are in. And, of course, most DSLs generated through the Toolkit will use T4 to generate code or other text-based artifacts. The property file will import the .targets file into the build. This is where all the item- and project templates live. With the build task complete and wrapped in a package we just need to get it called during a build. This is the approach I have gone with. The SDK project format supports generating packages without a .nuspec file. Text template directives provide general instructions to the text templating engine about how to generate the transformation code and the output file.

Because the binaries haven’t been built yet it won’t recognize them as inputs to Nuspec no matter what I’ve tried to do. The .props files are put into the build folder which will cause them to be injected into the build file. The control logic is written as fragments of program code in Visual C# or Visual Basic. Add NuGet packages for the required MSBuild packages. The pack target determines what files to include before the build runs. There are plusses and minuses to transforms.

Let’s create a database on your local SQL Server. The base change that will be made is that the .targets file that is shipped as part of the VS extension needs to move to a NuGet package. Here are the highlights, the code has the full version. The item template needs to be adjusted to handle the move from an extension-specific .targets file to a NuGet package. The text template transformation feature is named T4. Whenever you create the MVC project, Controller, View automated code is written by Visual Studio. 'Model' just indicates that the data can be defined in terms of the business concepts, rather than resembling the code. It does not have to be a UML model or a Domain-Specific Language model. This reduces the amount of configuration that goes into the config file and helps ensure the application will use the correct versions. Create the P3Net.BuildExtensions.TransformConfigs.props file in the package project. If you debug the templates that use the attribute 'hostspecific="true"', you get the exception without locking visual studio up. Alternatively, you can add a plain text file and set its Custom Tool property to TextTemplatingFilePreprocessor. The term model is sometimes used to describe data read by one or more templates. I created a Visual Studio extension called T4Editor that adds colors to different blocks in you code. They are executed within Visual Studio or MSBuild. The .targets file needs a couple of adjustments to play nice with the rest of the build system and use the new assembly where the custom task is defined. This required some changes to the TransformXmlFiles task to use the new type. The model can be in any format, in any kind of file or database. Instead we will look for the NuGet package. The existing web config transforms should run during the build and, as in the original article, you should have the transformed files ready for use. For example, your input data could be an XML file of configuration data. You don’t need environmental transforms in these environments anymore. As of Visual Studio 2017 15.9 I am unable to get the binary files to appear in the package file. For more information, see Design-Time Code Generation by using T4 Text Templates.

The last option is to not use the automated system at all but instead either do it via a post build event or manually. The problem is that the folder structure is rebuilt under the target folder. T4 Toolbox extends the code generation functionality of the T4 text templates in Visual Studio and allows you to: Generate multiple output files from a single text template; Automatically add output files to one or more projects and folders; Automatically add or check-out generated files from source control There are two kinds of T4 text templates: run time and design time. This process still works but as you start moving to build servers in the cloud or that don’t have Visual Studio installed you cannot rely on extensions being available. This helps resolve issues with trying to get MSBuild to load an assembly from an inline task like we had in previous versions of the extension. This is a minor change. Like the .targets file it needs to be copied to the output at build time. Design-time templates are therefore a useful tool in an agile development process. The config transform files containing the transformation rules remain unchanged. This is consistent with how popular packages are now injecting .targets files into the build process as well and reduces the dependencies needed to build a solution. Now copy the package file to your local NuGet store so you can add it to a project with a set of config transforms.

On the negative side you are exposing your settings to all your developers. You can access the currently output by calling this.GenerationEnvironment inside <# Control blocks #> .

T4 is used by developers as part of an application or tool framework to automate the creation of text files with a variety of parameters. Normally we would do this using a post-build event. To be found at build time the generated DLL needs to be copied to the tools folder. The environment config item template (actually the template wizard) currently looks for an import of the targets file so that it can report a warning if a project is using the template but hasn’t installed the extension yet. For more information, see Run-Time Text Generation with T4 Text Templates. If everything is correct then the .props file will be under the build folder and the .targets file under the tools folder. Create a new ASP.NET Web Application in Visual Studio. However this transformation occurs at build time and the modified file is stored directly in the output.

Update the extension version information. You can continue to use them as is. Generate multiple output files from a single text template ; Automatically add output files to one or more projects and folders ; Automatically add or check-out generated files from source control For example, you could create a template to define an HTML page: Notice that the template resembles the generated output. Overview. Go ahead and build the solution. Instead of trying to handle both approaaches to package references we’ll just look for the props file that the package installs. Here’s some of the things I’ve tried. Nuspec supports wildcards so you can do something like bin\**\*.dll to include binary files. C:\Program Files (or x86)\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplates\CSharp (or Visual Basic)\Web\MVC (or 2) 3\CodeTemplates.
