How to rename web.config transforms

Question

I am working in an ASP.net MVC 5 solution in Visual Studio 2015. I have the following web.config

How do I rename those to be

• Web.Integration.config
• Web.Staging.config
• Web.Production.config

When I right-click on those, I don't get a rename option!

Answer 1

You can copy the files, rename them and manually edit the .csproj file to include them (replacing the generated ones) like below:

<Content Include="Web.Integration.config">
   <DependentUpon>Web.config</DependentUpon>
   <SubType>Designer</SubType>
 </Content>
 <Content Include="Web.Staging.config">
   <DependentUpon>Web.config</DependentUpon>
   <SubType>Designer</SubType>
 </Content>
 <Content Include="Web.Production.config">
   <DependentUpon>Web.config</DependentUpon>
   <SubType>Designer</SubType>
 </Content>

Unfortunatelly I did not find a way to acomplish this through visual studio.

This is the third time I've set one of these up in a project and I get stuck every time. The key is that the config transform files are linked to the named build configurations.

If you go to Build > Configuration Manager... and select the Active solution configuration drop-down you can add new build names. Afterward you can right-click your web.config and Add Config Transform, which asks no questions and just creates one transform for each build.

Renaming an existing build didn't work, it still generated a transform with the original name, but you can delete builds or selectively delete the transform files.
