Update PostAction with symbol parameters to cmd file arguments

I need to pass symbols parameters to args when executing setup.cmd file using postActions property as below .template.config file.

Here, i am passing two symbols of type string jsonFileNamePath and myfilename as arguments to setup.cmd.

@wazzamatazz , thanks for the additional details. We are currently updating documents (working through that particular backlog). We can then move on to the “Template authoring” backlog, relevant to this issue. Please stay tuned.

@mlorbetske I think, it will be very useful - be able to pass the symbols in postAction. I’d like to solve a similiar use case.

I want to run command like this:

{
      "actionId": "3A7C4B45-1F5D-4A30-959A-51B88E82B5D2",
      "args": {
        "executable": "dotnet",
        "args": "run /seed --project src/(name).csproj"
      },
      "manualInstructions": [
        {
          "text": "Seeds the initial user database"
        }
      ],
      "continueOnError": false,
      "description ": "seeds the database"
    }

I need get the name of created csproj according user input. Any idea how to achieve that? Thx.
