Question

I am using T4 toolbox for cs file generation. But in result generates correct C# files but… without extension. What the problem?

<#@ template language="C#" hostspecific="true" debug="True" #>
<#@ output extension="txt" #>
<#@ include file="T4Toolbox.tt" #>
<#@ include file="$(ProjectDir)StoredProcedures.ttinclude" #>
<#@ include file="DB\SpGenerator.tt" #>
<#
/*
    <auto-generated>
    Do not change files!!
    </auto-generated>
*/
    var generator = new GeneratorSp();
    generator.tableName = ListOfTables();
    generator.Run();

Pass the file name, including its extension, to the Template.RenderToFile method:

_template.RenderToFile("FileName.sql");
