Hi

Trying to generate client code from a .net 9.0 .net core project, I get this error message :

I have only added a the path to my csproj file in the 'Project file path' field in the GUI.

It seems the problem is this line

The static resources manifest file 'C:\TDS\LAN.NET Core\TDS.GEO\TDS.GEO\bin\Debug\net9.0\NSwag.AspNetCore.Launcher.staticwebassets.endpoints.json' was not found.

In my bin folder the following file exist

'C:\TDS\LAN.NET Core\TDS.GEO\TDS.GEO\bin\Debug\net9.0\TDS.GEO.staticwebassets.endpoints.json'

So how can I get it to use my json file, not to use the prefix NSwag.AspNetCore.Launcher ?

Below is the complete error message.

I had the same issue, which seems to be caused by MapStaticAssets() when NSwag.MSBuild runs the project, I fixed it by replacing it with:

if (app.Environment.IsDevelopment())
{
    var assemblyTitle = Assembly.GetExecutingAssembly().GetCustomAttribute<AssemblyTitleAttribute>()?.Title;
    if (assemblyTitle is not null)
    {
        app.MapStaticAssets($"{assemblyTitle}.staticwebassets.endpoints.json");
    }
}
else
{
    app.MapStaticAssets();
}
