Cannot run spacetime publish when csproj + sln live in same folder

[AndreasHassing]

I've been going through https://spacetimedb.com/docs/unity/part-3.

When opening the server-csharp folder in VS Code:

cd C:\dev\unity-games\blackholio\server-csharp
code .

It (C# DevKit?) automatically creates a server-csharp.sln file in the same folder as StdbModule.csproj.

After this, if I run spacetime publish --server local blackholio I get an error:

MSBUILD : error MSB1011: Specify which project or solution file to use because this folder contains more than one project or solution file.
Error: command ["dotnet", "publish", "-c", "Release", "-v", "quiet"] exited with code 1

There is no way to specify that StdbModule.csproj should be built.

--build-options is only used to specify additional options to the spacetime build command which gets invoked as part of spacetime publish.

Just put it in a directory (module in blow).
like this:

│  spacetimedb.sln
│
└─── module
        .gitignore
        global.json
        Lib.cs
        StdbModule.csproj

│  spacetimedb.sln
│
└─── module
        .gitignore
        global.json
        Lib.cs
        StdbModule.csproj

That works, too. I just created a PowerShell script to temporarily rename the sln-file before invoking spacetime CLI.

To avoid others having the same problem, it may make sense to fix it at the source 😊.

Will fix, ticket has been triaged 👍

VS Code also has a setting to prevent this, which is disabled by default:
