Describe the bug

I am encountering a strange problem.

In our application I have a single controller where PUT, DELETE, POST getting 405 error while the rest of controllers are working properly.

here is how my Web.Config is:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
        <handlers>
            <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
            <remove name="WebDAV"/>
        </handlers>
        <modules runAllManagedModulesForAllRequests="true">
            <remove name="WebDAVModule"/>
        </modules>
        <aspNetCore processPath="dotnet" 
                    arguments=".\WebUI.dll" 
                    stdoutLogEnabled="false" 
                    stdoutLogFile=".\logs\stdout" 
                    hostingModel="inprocess" />
        <httpProtocol>
            <customHeaders>
                <clear />
                <add name="Access-Control-Expose-Headers " value="*"/>
                <add name="Access-Control-Allow-Origin" value="*" />
                <add name="Access-Control-Allow-Methods" value="*" />
                <add name="Access-Control-Allow-Headers" value="*" />
                <remove name="X-Powered-By" />
            </customHeaders>
        </httpProtocol>
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: B10BA5B4-B02C-4528-9272-8478A9F7B038-->

Here is my startup.cs

// configure services
        #region CORS

        services.AddCors(options =>
        {
            options.AddPolicy(
                AllowedOrigins,
                builder =>
                {
                    builder.AllowAnyOrigin()
                        .AllowAnyHeader()
                        .AllowAnyMethod();
                });
        });

        #endregion

// under configure
    app.UseCors(AllowedOrigins);

From controller I am getting this Response header:

using Application.TableObjects;
using Application.TableObjects.Commands;
using Application.TableObjects.Queries;
using MediatR;
using Microsoft.AspNetCore.Mvc;
using RI.QueryExecutor;

namespace WebUI.Controllers;

public class ListTableController : ApiControllerBase
{
    public ListTableController(ISender sender, IHttpContextAccessor httpContextAccessor)
        : base(sender, httpContextAccessor) { }

    [HttpPost("save")]
    public async Task<IResult<TableIndexDto>> CreateAsyc([FromBody] CreateTableIndex request)
        => await Mediator.Send(request);

    [HttpDelete("save")]
    public async Task<IResult<TableIndexDto>> UpdateAsyc([FromQuery] DeleteTableIndex request)
        => await Mediator.Send(request);

    [HttpPut("save")]
    public async Task<IResult<TableIndexDto>> UpdateAsyc([FromBody] UpdateTableIndex request)
        => await Mediator.Send(request);
}

angular service:

post<TPost, TOut>(url: string, param: TPost): Observable<TOut> {
    return this
      .http
      .post<TOut>(url, param, this.buildHttpOptions())
      .pipe(catchError(_ => this.handleError(_)));
  }

  private buildHttpOptions(): { headers: HttpHeaders; } {
    return {
      headers: this.buildBaseHeaders()
    };
  }

  private buildBaseHeaders(): HttpHeaders {
    const lang: string = 'it';
    const user:string = STRING_EMPTY;
    const datow: string = STRING_EMPTY;
    return new HttpHeaders(this.GetHttpHeaderObject(user, lang, datow));
  }

  private GetHttpHeaderObject(user: string, lang: string, datow: string) : any {
    return {

Can you try issuing the request with curl to see if it works that way? I suspect that your client app is not using the correct path but I don't know angular so this is just a guess. But if we can confirm that the endpoints work from curl that would point in that direction.
