我有以下代码，我正在尝试使用ef core更新ClientAccount，但是它们并发检查失败：

    public class ClientAccount
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public long Id { get; set; }

        [Required]
        [ConcurrencyCheck]
        public double Balance { get; set; }

        [Required]
        public DateTime DateTimeCreated { get; set; }

        [Required]
        public DateTime DateTimeUpdated { get; set; }       
    }

    public class ClientRepository
    {
        private readonly MyContext context;

        public ClientRepository(MyContext context)
        {
            this.context = context;
        }

        public ClientAccount GetClientAccount()
        {
            return (from client in context.ClientAccount
                    select client).SingleOrDefault();
        }

        public void Update(ClientAccount client)
        {
            context.Update(client);
            context.Entry(client).Property(x => x.DateTimeCreated).IsModified = false; …

我已将标题单元格和单元格的样式设置为右对齐，但标题仅与单元格文本对齐

这是一个示例的链接

我已经添加了

.mat-cell, .mat-header-cell {
    text-align: right;
}

我在 Asp.Net Core 3.1 中有以下代码

public void ConfigureServices(IServiceCollection services)
{
    services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        }).AddJwtBearer();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseRouting();

    app.UseCors(DefaultCorsPolicyName);

    app.UseAuthentication();
    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
    endpoints.MapControllerRoute("default", "{controller}/{action}/{id?}").RequireAuthorization(new AuthorizeAttribute());
    });
}


[ApiController]
[Route("[controller]/[action]")]
public class TestController : ControllerBase
{
    [HttpGet]
    public string Test()
    {
        return "Test works!";
    }
}

但所有请求都通过并且没有授权工作。知道为什么会这样吗？

我有以下通过 Visual Studio 2019 创建的 pubxml 文件：

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <WebPublishMethod>FileSystem</WebPublishMethod>
    <PublishProvider>FileSystem</PublishProvider>
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
    <LastUsedPlatform>Any CPU</LastUsedPlatform>
    <SiteUrlToLaunchAfterPublish />
    <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
    <ExcludeApp_Data>False</ExcludeApp_Data>

    <publishUrl>bin\Release\netcoreapp3.1\publish\</publishUrl>
    <DeleteExistingFiles>True</DeleteExistingFiles>
  </PropertyGroup>
</Project>

当我运行dotnet.exe publish src\MyProject.Web.sln -p:PublishProfile=Properties\PublishProfiles\ProductionPublish.pubxmlRelease 不包含任何内容并且发布发生在 Debug 文件夹（调试版本）上。为什么会发生这种情况并且忽略 pubxml？

更新 #1

Structure
src\MyProject\MyProject.csproj
src\MyProject.Utils\ect.Utils.csproj
src\MyProject.Web\MyProject.Web.csproj
src\MyProject.Web.sln

和 pubxml 的路径

src\MyProject.Web\Properties\PublishProfiles\ProductionPublish.pubxml

我有一个项目需要查询数据库并将结果返回到 web api。有几个存储过程是由 DB Admin 即时创建的，它们有一个 UI，用于创建存储过程的定义和它的名称，Web api 服务只调用该 SP 并应该返回结果。根据下面的代码，我无法将返回对象返回到 web api 控制器，因为对象包含项目但没有映射属性。

var result = dbContext.Query<object>().AsNoTracking().FromSql(
            "dbo.MY_SP @DateFrom=@DateFrom, @DateTo=@DateTo",
            dateFromParam, dateToParam).ToList();

当我尝试调用我的项目上的控制器时，我收到以下错误，该控制器使用 oWin 和 Quartz.Net 3.0.7 和 Autofac 。

{
"Message": "An error has occurred.",
"ExceptionMessage": "An error occurred when trying to create a controller of type 'QuartzController'. Make sure that the controller has a parameterless public constructor.",
"ExceptionType": "System.InvalidOperationException",

我有以下代码，当我调用 api 端点时出现错误 Bearer was not authenticated. Failure message: IDX10500: Signature validation failed. No security keys were provided to validate the signature.

services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(cfg =>
{
    cfg.RequireHttpsMetadata = false;
    cfg.TokenValidationParameters = new TokenValidationParameters
    {
        ValidateAudience = false,
        ValidateIssuer = false,
        ValidateIssuerSigningKey = false
    };
});

如果我设置了，为什么会发生这种情况ValidateIssuerSigningKey=false？

我正在使用最新的Serilog.File 4.1.0和Serilog.Sinks.Async. 异步日志记录有效，但我希望滚动文件。如何启用文件滚动？

我有以下内容：

 Log.Logger = new LoggerConfiguration()
                .WriteTo.Async(a =>
                {
                    a.File("logs/logs.log");
                })
                .MinimumLevel.Verbose()
                .CreateLogger();

我为 VS2019 创建了一个自定义模板，其中包含两个项目。下面是我的 root.vstemplate 文件

<VSTemplate Version="3.0.0" Type="ProjectGroup" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005">
  <TemplateData>
    <Name>Asp.Net Core Template EF Core</Name>

    </ProjectSubType>
    <SortOrder>1000</SortOrder>
    <CreateNewFolder>true</CreateNewFolder>
    <DefaultName>Asp.Net Core Template EF Core</DefaultName>
    <ProvideDefaultName>true</ProvideDefaultName>
    <LocationField>Enabled</LocationField>
    <EnableLocationBrowseButton>true</EnableLocationBrowseButton>
    <Icon>logo.png</Icon>
  </TemplateData>
  <TemplateContent>
    <ProjectCollection>
      <ProjectTemplateLink ProjectName="AspNet Core Ef Core">
        src\AspNetCore3EfCoreTemplate\MyTemplate.vstemplate
      </ProjectTemplateLink>
      <ProjectTemplateLink ProjectName="AspNet Core Ef Core Web">
        src\AspNetCore3EfCoreTemplate.Web\MyTemplate.vstemplate
      </ProjectTemplateLink>
    </ProjectCollection>
  </TemplateContent>
</VSTemplate>

我按照此链接的说明进行操作，但是当我尝试在 VS2019 中创建新项目时未显示我的模板。有谁知道为什么会这样？

我有一个只有一列的 csv，我正在使用 Papa Parse 库来解析 csv。我收到以下错误Unable to auto-detect delimiting character; defaulted to ','

由于它只是一列，因此它不是逗号分隔值。我试图将 delimeter 配置属性设置为 autodelimiter: "",但仍然是同样的问题

当使用 Primeng 表格并将表格设置为可滚动时，表格应显示滚动条，并且单元格内的文本不应溢出。相反，这不会发生。

在Stackblitz 中检查此示例并调整大小
