.NET 6 UseWindowsService()引发异常

Question

这是我在program.cs中的“完整”代码。

var builder = WebApplication.CreateBuilder(args);

builder.Host.UseWindowsService();

// Add services to the container.
builder.Services.AddGrpc();

var app = builder.Build();

// Configure the HTTP request pipeline.
app.MapGrpcService<GreeterService>();
app.MapGet("/", () => "error");

app.Run();

套餐：

• Grpc.AspNetCore(2.47.0)
• Microsoft.Extensions.Hosting.WindowsServices (6.0.0)

我部署了一个测试服务器，并尝试启动service...and，我在事件日志中得到了这样的结果：

应用程序: PartReservationGrpc.exe CoreCLR版本: 6.0.622.26707 .NET版本: 6.0.6描述:进程由于未处理的异常而终止。异常信息: System.NotSupportedException:内容根目录从“C：\windows\system32 32”更改为“D：\CMAP\iceman\part订制”。不支持使用WebApplicationBuilder.Host更改主机配置。使用WebApplication.CreateBuilder(WebApplicationOptions)代替。(在Microsoft.AspNetCore.Builder.ConfigureHostBuilder.ConfigureHostConfiguration(Action1 configureDelegate) at Microsoft.Extensions.Hosting.HostingHostBuilderExtensions.UseContentRoot(IHostBuilder hostBuilder, String contentRoot) at Microsoft.Extensions.Hosting.WindowsServiceLifetimeHostBuilderExtensions.UseWindowsService(IHostBuilder hostBuilder, Action1配置) at Microsoft.Extensions.Hosting.WindowsServiceLifetimeHostBuilderExtensions.UseWindowsService(IHostBuilder hostBuilder) at Program.$(String[] args)在C:\Users\WuJ22\source\Workspaces\C5CG2133PXF\gRPC\PartReservation\PartReservation\PartReservationGrpc\Program.cs:line 33中

第33行:正是UseWindowsService()的生成位置。

有人遇到过这个问题吗？

答案可以找到here

诀窍是用CreateBuilder()调用WebApplicationOptions来设置ContentRootPath.
