  • UI type: Blazor
  • DB provider: EF Core
  • Tiered (MVC) or Identity Server Separated (Angular): no
  • Exception message and stack trace:
  • Steps to reproduce the issue:"

I have this method in a MenuContributor class in my Blazor project: <br>

    private async Task<Guid> GetFirstProjectAsync(Guid sltnId)
    {
        Console.WriteLine($"SLTNID = {sltnId} ");

        var projectFilter = new GetProjectsInput
        {
            SltnId = new Guid("00000000-14ba-4f0f-8417-c2f312768aea")
        };

        projectFilter.MaxResultCount = PageSize;
        projectFilter.SkipCount = (CurrentPage - 1) * PageSize;
        projectFilter.Sorting = CurrentSorting;

        var result = await _projectsAppService.GetListAsync(projectFilter);  <--- THIS IS WHERE THE EXCEPTION HAPPENS

        if (result.Items.FirstOrDefault() != null)
        {
            return result.Items.FirstOrDefault().Id;
        }
        else
        {
            Guid defaultGuid =  default;
            return defaultGuid;
        }

    }

It returns the following exception:

>> mono_wasm_start_single_stepping 2 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]       Unhandled exception rendering component: Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it (or one of its parent scopes) has already been disposed.

However, I replicated the logic in a test method in my Application.Tests test project and the logic worked fine without exception.

Is it something to do with GUID?

This the class its trying to return:

    public class ProjectDto : FullAuditedEntityDto<Guid>     {         public string Name { get; set; }         public string Description { get; set; }         public int DisplayOrder { get; set; }         public List<ProjectConformDto> ProjectConforms { get; set; }     }

Happy to provide the project if required.

    I've sent you a project. The class that has the issue is SolutionMenuContributor in the Blazor project. The test class/method is ProjectApplicationTests class GetListAsyncForSltn method in the Datansa.App.Application.Tests project.

    I had commented out the code in the SolutionMenuContributor , GetFirstProjectAsync method.

    Did you uncomment it before you tested. SolutionMenuContributor still doesn't work for me, although the test class does. This is the issue.

    You will also need to remove "return new Guid();" at the start of the GetFirstProjectAsync method.
