You mean like this: <#+ public List<string> Dostuff() { List<string> result = new List<string>(); // … return result; } #> Here’s a complete example: Reading a Xml File in T4 Templates Oleg Sych’s T4Toolbox is a good resource.
You could use Scripty. It looks quite nice and fits with the new Analyzers from Roslyn. http://daveaglick.com/posts/announcing-scripty https://github.com/daveaglick/Scripty Since they are dropping the project.json format (https://blogs.msdn.microsoft.com/dotnet/2016/05/23/changes-to-project-json/) you should be able to use Scripty from the .xproj or .csproj file.
Try the Tangible T4 Editor extension. There’s a free version you can grab to try it out, but if you use them often, it’s worth getting the pro license.
You have a case of temporal coupling there, i.e. you’re mixing the check whether the entity has changed with the assignments. If you separate the two, your code becomes much cleaner: protected override bool ModifyExistingEntity(Product entity, ProductModel item) { bool isModified = this.IsEntityModified(entity, item); if (isModified) { this.UpdateEntity(entity, item); } return isModified; } private bool … Read more
See The Host Specific Parameter section HERE. This snippet shows how to get the full path of src relative to the template. <#@ template hostspecific=”true” #> // The location of the src folder relative to the t4 template: // <#= Host.ResolvePath(“src”) #>
T4 works nearly completely independent from the rest of your code. You’re on the right track though, with the assembly directive, but you’ll need to specify a full path to the actual DLL of the assembly, unless the assembly is in the GAC (which it probably isn’t). Luckily, however, you can use MSBuild macros in … Read more
This happens when Visual Studio gets itself confused and briefly decides that it can’t use Foo.cs as the output for some reason (usually hallucinatory), so it will use Foo1.cs instead, and then insists on remembering this setting. The fix is to open the .csproj file in a text editor and locate the Foo.tt entry. This … Read more
Resharper can do this, with the help of the ForTea Plugin that adds support for editing T4 (.tt) files.
To include comments as part of control code, they need to be inside a code block of some sort, for example <# // Hello this is a comment #> or <#+ // Hello this is a comment in a class feature block #> Sometimes you need to push the close tag to the next line … Read more
There a few things you need to change inside the .tt file. I choose to use the third solution you suggested but this requires to be formatted like FK_CollectionName_RelationName. I split them up with ‘_’ and use the last string in the array. I use the RelationName with the ToEndMember property to create a property … Read more
