Question

我有一个托管在Asp .Net Core 5 Web API中的Blazor Wasm应用程序。全部使用带有身份验证的vs 2019模板生成。在调试或发布版本中，一切都可以完美运行。但是，当我在“文件夹配置文件”中发布此应用程序并运行后，在浏览器控制台中出现了以下异常：

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Arg_NullReferenceException
System.NullReferenceException: Arg_NullReferenceException
   at Chatory.Client.Components.Contacts.<>c__DisplayClass0_0.<BuildRenderTree>b__1(RenderTreeBuilder __builder2)
   at Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.AddContent(Int32 sequence, RenderFragment fragment)
   at Microsoft.AspNetCore.Components.Authorization.AuthorizeViewCore.BuildRenderTree(RenderTreeBuilder builder)
   at Microsoft.AspNetCore.Components.ComponentBase.<.ctor>b__6_0(RenderTreeBuilder builder)
   at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.RenderInExistingBatch(RenderQueueEntry renderQueueEntry)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.ProcessRenderQueue()

和另一个：

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Arg_NullReferenceException
System.NullReferenceException: Arg_NullReferenceException
   at Chatory.Client.Components.Contacts.<>c__DisplayClass0_0.<BuildRenderTree>b__1(RenderTreeBuilder __builder2)
   at Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.AddContent(Int32 sequence, RenderFragment fragment)
   at Microsoft.AspNetCore.Components.Authorization.AuthorizeViewCore.BuildRenderTree(RenderTreeBuilder builder)
   at Microsoft.AspNetCore.Components.ComponentBase.<.ctor>b__6_0(RenderTreeBuilder builder)
   at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.RenderInExistingBatch(RenderQueueEntry renderQueueEntry)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.ProcessRenderQueue()

因为我在构建（调试/发布）时没有这些异常，所以我无法对其进行调试！！！这些例外会在发布后出现！！！

解决这个问题的任何想法？？？

我没有清理并重建解决方案...没有帮助...

发布后Blazor Wasm托管的客户端（控制台）异常
