How can I use global variables in a TT file? If I declare a variable in the header I get a compile error if I reference it in a function. <#@ template debug="false" hostspecific="false" language="C#" #> <#@ output extension=".cs" #> <# int ValueForThisFile = 35; SomeFunction(); #> <#+ void SomeFunction() { #> public void GeneratedCode() { int value = <#=ValueForThisFile#>; } <#+ } #> I know that I could pass it as an argument but there are hundreds of calls and it would be syntactically tighter if I could avoid that. If this were one file I could hard code the value but there are dozens of

In an application scaffolding project on which I'm working, I'm trying to decide whether to use Oslo , T4 or CodeDom for generating code. Our goals are to keep dependencies to a minimum and drive code generation for a domain driven

Our Solution is currently based on Entity Framework Database First. We have a T4 Template that generates repository classes from the EDMX. We are reviewing our planned approach for releasing changes, especially Database changes. If we continue with Database first, then we will need to separately generate scripts to change the development and other databases. It seems that with Code First, we simply change the model and that generates scripts to change the various databases. This seems more straightforward, does not involve hand crafting scripting processes and lower risk. So, if we make the

Is it possible to run T4 code generation without needing Visual Studio 2010? Basically I have to build an in house ORM (don't ask..if I had a choice I wouldn't). I was planning to use subsonic as a base but change some things and how they work. However my main question is can I run T4 from an external application that I write, so I can use the features of T4? Or am I better off doing it myself (which I doubt)? Michael Maddox TextTransform.exe will do what you want for simple scenarios: http://msdn.microsoft.com/en-us/library/bb126245.aspx Here is how to run a T4 template from your own code for

I have come across a scenerio that to customize DataAnnotations in Dynamic Data Web Application. This is the scenerio: [Display(Name="DispName")] public string DName{get;set;} Instead of hardcoding Name="DispName" for Display DataAnnotation, I want to fetch some value from DataBase and fit int the Name attribute. like: [Display(Name=SomeValueFromDB)] public string DName{get;set;} Is there any way to show the Name attribute of Display DataAnnotation from database instead of hardcoding its value? Also how can I change the ScaffoldColumn(True/false) based on table values? Can I do this using T4

I am generating POCOs (lets say they are subclasses of MyEntityObject ) by using a T4 template from an EDMX file. I have 3 entities, e.g.: MyTable1 (PrimaryKey: MyTable1ID) MyTable2 (PrimaryKey: MyTable2ID) MyTable3 (PrimaryKey: MyTable3ID) These entities have the following relations: MyTable1.MyTable1ID <=> MyTable2.MyTable1ID (MyTable1ID is the foreign key to MyTable1) MyTable2.MyTable2ID <=> MyTable3.MyTable2ID (MyTable2ID is the foreign key to MyTable2) Or in another view: MyTable1 <= MyTable2 <= MyTable3 I want to extract all foreign key relations NavigationProperty[] foreignKeys = entity

I've written a T4 template where I instantiate an EF context to read some data. The problem is that the context cannot see the connection string from the Web.config. How can I make the connection strings from the Web.config available to the template? More info: template is written from scratch EF edmx is located in another project the first query I make in the template tells me that it cannot find the required connection string in the project where the template resides Tried some of the solutions (thank you) below but I get this: Error 2 Compiling transformation: 'Microsoft.VisualStudio
