Passingwind

1，安装包 VueCliMiddleware 

2，startup.cs 添加代码

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddSpaStaticFiles(options =>
    {
        options.RootPath = "ClientApp/dist";
    });
}


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{ 

    app.UseStaticFiles();

    // dist 
    app.UseSpaStaticFiles();

    // app.UseMvc...

    app.UseSpa(b =>
    {
        b.Options.SourcePath = "ClientApp";
#if DEBUG
        if (env.IsDevelopment())
        {
            b.UseVueCli("serve");
        }
#endif

    });
}

3，csproj 添加
