Using VS 2019, .net core 2.1, Windows 10 Surface Pro on an ASP.NET Core app, when I run electronize init (via command prompt) I receive the following error:

C:\source\repos\TranslationMessageManager>electronize init
Adding our config file to your project...
Search your .csproj to add the needed electron.manifest.json...
Found your .csproj:  - check for existing config or update it.

There isn't anything in that message that makes it clear to me what might be going on here - just figured I would report it in here in case it makes sense to someone on the team :)

Thanks!

I am closing this ticket as I am pretty certain the issue was that I was using Pages template rather than MVC template, although it could have been numerous other things. I was combining out-of-date usage instructions with up-to-date instructions.

I'm experiencing same issue. For me this is happening every time.
I'm creating new .net server-side blazor project on VS 2019. Then I added added ElectronizeNET.API nuget version 9.31.2 and entries to startup.cs and program.cs. The I run electronize init and get the error.
I'm using .net core version 3.1.

I could resolve a problem. I m should be in the folder where are the Startup.cs and Program.cs when I execute this commands.
I expect that this resolve yours problems too.

I recommend you guys open a new issue and provide as much detail as possible. It has been a long time since I personally saw this issue, and I don't recall specifically what the issue was or how I solved it.

So here's the thing:

At the following step:

At the first time, you need an Electron.NET project initialization. Type the following command in your ASP.NET Core folder:

$ electronize init

Be sure you cd to the correct folder in advance:

So if your folder structure is:

├── project
│   └── Startup.cs
└── project.sln

Then in the Terminal do this:

$ cd project
$ electronize init
$ cd ..
$ electronize start

@goonzaah That solution worked for me! (I have an ASP.NET Web Application MVC).
Just to reiterate the answer:
cd into the directory containing Program.cs and Startup.cs and run electronize init in there.
