Hi,

We have developed a ASP.NET Core Controller API that work.

From we updated Visual Studio from 17.10.4 to 17.11.5, when the API is started in debug from Visual Studio, the memory consumption is rising rapidly :

The API work fine when started by executing the exe from cmd and next attach to Visual Studio debugger. So sound the problem come from Visual Studio.

When I pause and check the stack trace :

...
Microsoft.AspNetCore.Mvc.ApiExplorer.dll!Microsoft.AspNetCore.Mvc.ApiExplorer.DefaultApiDescriptionProvider.PseudoModelBindingVisitor.Visit(Microsoft.AspNetCore.Mvc.ApiExplorer.DefaultApiDescriptionProvider.ApiParameterDescriptionContext bindingContext, Microsoft.AspNetCore.Mvc.ModelBinding.BindingSource ambientSource, string containerName)    Unknown
Microsoft.AspNetCore.Mvc.ApiExplorer.dll!Microsoft.AspNetCore.Mvc.ApiExplorer.DefaultApiDescriptionProvider.GetParameters(Microsoft.AspNetCore.Mvc.ApiExplorer.ApiParameterContext context)               Unknown
Microsoft.AspNetCore.Mvc.ApiExplorer.dll!Microsoft.AspNetCore.Mvc.ApiExplorer.DefaultApiDescriptionProvider.CreateApiDescription(Microsoft.AspNetCore.Mvc.Controllers.ControllerActionDescriptor action, string httpMethod, string groupName)    Unknown

Microsoft.AspNetCore.Mvc.ApiExplorer.dll!Microsoft.AspNetCore.Mvc.ApiExplorer.ApiDescriptionGroupCollectionProvider.GetCollection(Microsoft.AspNetCore.Mvc.Infrastructure.ActionDescriptorCollection actionDescriptors)           Unknown
Microsoft.AspNetCore.Mvc.ApiExplorer.dll!Microsoft.AspNetCore.Mvc.ApiExplorer.ApiDescriptionGroupCollectionProvider.ApiDescriptionGroups.get()               Unknown
Microsoft.WebTools.ApiEndpointDiscovery.dll!Microsoft.WebTools.ApiEndpointDiscovery.ApplicationEndpointWriter.WriteEndpointsAsync(string fileName, System.IServiceProvider serviceProvider, System.Threading.CancellationToken cancelToken)      Unknown
Microsoft.WebTools.ApiEndpointDiscovery.dll!Microsoft.WebTools.ApiEndpointDiscovery.HostingStartup.Configure.AnonymousMethod__1()               Unknown
System.Private.CoreLib.dll!System.Threading.CancellationTokenSource.Invoke(System.Delegate d, object state, System.Threading.CancellationTokenSource source)          Unknown

System.Private.CoreLib.dll!System.Threading.CancellationTokenSource.ExecuteCallbackHandlers(bool throwOnFirstException)  Unknown
Microsoft.Extensions.Hosting.dll!Microsoft.Extensions.Hosting.Internal.ApplicationLifetime.NotifyStarted()               Unknown
Microsoft.Extensions.Hosting.dll!Microsoft.Extensions.Hosting.Internal.Host.StartAsync(System.Threading.CancellationToken cancellationToken)           Unknown
Microsoft.Extensions.Hosting.Abstractions.dll!Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(Microsoft.Extensions.Hosting.IHost host, System.Threading.CancellationToken token)             Unknown
Microsoft.Extensions.Hosting.Abstractions.dll!Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.Run(Microsoft.Extensions.Hosting.IHost host)      Unknown
MyPorject.Api.dll!Program.<Main>$(string[] args)

I think Microsoft.WebTools.ApiEndpointDiscovery.dll is responsible. It try to explore endpoint, as the endpoint has recursive parameter, it do infinite loop.

We have computers where Visual Studio isn't updated and the API work in debug. See Visual Studio Info
