Project structure

T4BLL add bll.tt file;

T4model add model file;

T4dal add dal.tt file;

T4dal add the ADO Entity Data model to select Dababase First mode;

Open Model1.tt Open under the model1.edmx file, the copied content replaces the Model.tt file under the T4model project;

Open Model.tt under Model1.edmx file from <#=codestringgenerator.entityclassopening (entity) #>{ Select to } <# Endnamespace (code); Delete

Such as

Copy model1.tt content replace Bll.tt, dal.tt content, now Model1.tt has no meaning, can be deleted.

Open the T4model T4 template, modify the following code, after the modification is complete, you can generate the model of the Add class in the EDMX.

Const string @" MODEL1.EDMX " ; // Change to string inputfile = host.resolveassemblyreference ("$ (projectdir)"). Replace ("t4model","t4dal") +"  /MODEL1.EDMX"

Open the T4dal T4 template

Filemanager.startnewfile (entity. Name +". CS");//Change toFilemanager.startnewfile (entity. Name +"_dal.cs");//---split line---  Public stringentityclassopening (EntityType entity) {return string. Format (CultureInfo.InvariantCulture,"{0} {1}partial class {2}{3}", Accessibility.fortype (entity), _code. SpaceAfter (_code. Abstractoption (entity)), _code. Escape (entity), _code.

Open the T4BLL T4 template

Const stringInputfile =@"MODEL1.EDMX";//Change tostringInputfile = Host.resolveassemblyreference ("$ (ProjectDir)"). Replace ("T4BLL","T4dal")+"/MODEL1.EDMX"; //---split line---Filemanager.startnewfile (entity. Name +". CS");//Change toFilemanager.startnewfile (entity.

Host.resolveassemblyreference ("$ (ProjectDir)") is the way to get the project path, by replacing the project name to find the edmx file, which enables the T4 template to be detached from the different class libraries.
