Net Web 应用程序添加灰色配置变换

我在解决方案中添加了一个现有的 ASP.Net Web 应用程序项目。除了标准的调试和发布配置之外，这个解决方案还有两个自定义配置，SAT 和 UAT。对于新的 Web 应用程序，右键单击 Web。配置显示了上下文菜单，但是“添加配置变换”的选项是灰色的。

我不知所措。这个新项目是一个网络应用程序。配置管理器没有显示此项目的两个自定义配置，但是它为其他项目显示了这两个自定义配置。项目似乎在解决方案文件中具有正确的条目。

有什么想法吗？

You must first define the configurations in the Configuration Manager. To be sure you are bringing up the Configuration Manager, you can access it by going to: Build->Configuraton Manager

In the Active Solution Configuration dropdown, select <New...>. Once you've added, you will then be able to "Add Config Transform".

Don't edit your solution file directly. It will only cause headaches.

As we work with PublishProfiles, for me the answer was right-clicking the relevant pubxml file (found in the project folder Properties subfolder PublishProfiles) and then selecting Add Config Transform. No managers needed ;).

In my case, in Visual Studio 2015, when I created a new solution based on a project template, Add Config Transform was greyed out - but for a different reason:

Clicking on "Show all files" revealed the files were already there - only hidden. Hence, the button was greyed out (because there is no need to add them as they are already there).

  1. Click "Show all files" icon:
    enter image description here

  2. Now you can expand "Web.config":
    enter image description here

  3. Double click on any of the transform files (Web.Debug.config or Web.Release.config) to open and edit it.

Notes:

  • I did not want to add an additional configuration, just use Debug and Release. If you create one, select it, and the transform file does not exist yet, then the context menu item Add Config Transform is active and not greyed out.

  • Another way is to delete (or move the files outside of the project directory), then re-create them from scratch (via Add config transform).
    Because they are not there any more, the menu shouldn't be greyed out. It might be necessary to close and re-open the solution after you've removed the files.

  • If you want to create additional configuration transform files, keep in mind that in Visual Studio, config transforms are correlated with configurations.
    To add another transform, you need to add a new configuration first. In order to add another one, do the following:
    Via the configuration manager (the dropdown where you can select Debug or Release), add a new configuration first, e.g. myNewConfig. Then select myNewConfig. Now select Web.config in the Solution Explorer, right click and select in the context menu "Add Config Transform":
    It will create Web.myNewConfig.config. Once it exists, the context menu will be grayed out again, because VS only allows one transform per configuration.

To get this working i had to add new property groups to my csproj file.

Add Config Transform was grayed out.

i added the following XML to my csproj and reloaded the project. then Add Config Transform was available. once selected my addition transforms were added

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'IAT_CMCD|AnyCPU'">
<DebugType>pdbonly</DebugType>
<Optimize>true</Optimize>
<OutputPath>bin\</OutputPath>
<DefineConstants>TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'UAT_CM|AnyCPU'">
<DebugType>pdbonly</DebugType>
<Optimize>true</Optimize>
<OutputPath>bin\</OutputPath>
<DefineConstants>TRACE</DefineConstants>
<ErrorReport>prompt</ErrorReport>
<WarningLevel>4</WarningLevel>
</PropertyGroup>

I solved this by realizing two things:

  1. There is a Solution level configuration, and there are Project level configurations. The web.MyConfigName.config is created based on project level configurations.
  2. It seems that Visual Studio 2017 Configuration Manager bases what configurations to add from the (hidden) obj folder. Deleting the obj folder for the project and rebuilding will update the project with the configurations you've added.

To make the option "add config transform" available follow these steps:

  1. Make sure you have enabled to Show Hidden Files
  2. Open configuration manager for the Solution
  3. Pick the relevant Solution config, then in the dropdown next to your project pick <New..> or <Edit..> and add, remove or edit what Project configs you want.
  4. Delete the obj folder in your project. Rebuild. Make sure you save the changes to your project and solution files. I also restarted visual studio, because why not. Verify that you see all your project configs as folders in your obj folder.
  5. Right-click web.config and add your config transformation.

Hope it helps someone. :)
