t4 generate file with no DependentUpon attribute in csproj file

We are using t4 templates for managing configurations in our project. And web.config file is generated via web.tt file. After generation in csproj file I have following:

<Content Include="Web.config">
  <AutoGen>True</AutoGen>
  <DesignTime>True</DesignTime>
  <DependentUpon>Web.tt</DependentUpon>
</Content>

Is it possible to configure t4 template somehow to generate independent web.config file, not under web.tt?

Web.config file depends upon web.tt

Yes you can. First define a save routine in a T4 include file.

SaveOutput.tt:

<#@ template language=“C#” hostspecific=“true” #>
<#@ import namespace=“System.IO” #>
<#+
  void SaveOutput(string fileName)
  {
      string templateDirectory = Path.GetDirectoryName(Host.TemplateFile);
      string outputFilePath = Path.Combine(templateDirectory, fileName);
      File.WriteAllText(outputFilePath, this.GenerationEnvironment.ToString()); 

      this.GenerationEnvironment.Remove(0, this.GenerationEnvironment.Length);
  }
#>

Now every time you call SaveOutput with a file name it will write the current buffer to that external file. For example.

Web.tt:

<#@ include file=“SaveOutput.tt” #>
<#
    GenerateConfig();
    SaveOutput(”..\..\Web.Config”);  
#>

If you want to generate multiple files:

<#@ include file=“SaveOutput.tt” #>
<#
    GenerateFile1();
    SaveOutput(”..\..\File1.txt”);  

    GenerateFile2();
    SaveOutput(”..\..\File2.txt”); 
#>
