ToRfc1123String fails as InplaceStringBuilder from Microsoft.Extensions.Primitives has been removed in v5.0.0

Describe the bug

The method ToRfc1123String fails with Microsoft.Extensions.Primitives v5.0.0 as the method InplaceStringBuilder has been removed. Workaround is to downgrade to Microsoft.Extensions.Primitives v3.1.10

To Reproduce

Execute Microsoft.AspNetCore.Http.HttpResponseWritingExtensions.WriteAsync(HttpResponse response, String text, CancellationToken cancellationToken) e.g. (HTTPContext)context.Response.WriteAsync("some sort of string");

Exceptions (if any)

See the call stack

System.TypeLoadException HResult=0x80131522 Message=Could not load type ‘Microsoft.Extensions.Primitives.InplaceStringBuilder’ from assembly ‘Microsoft.Extensions.Primitives, Version=5.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60’. Source=Microsoft.Net.Http.Headers StackTrace: at Microsoft.Net.Http.Headers.DateTimeFormatter.ToRfc1123String(DateTimeOffset dateTime, Boolean quoted) in //src/Microsoft.Net.Http.Headers/DateTimeFormatter.cs:line 65 at Microsoft.Net.Http.Headers.HeaderUtilities.FormatDate(DateTimeOffset dateTime, Boolean quoted) in //src/Microsoft.Net.Http.Headers/HeaderUtilities.cs:line 592

Which then propagates up the call stack like so

System.NullReferenceException HResult=0x80004003 Message=Object reference not set to an instance of an object. Source=Microsoft.AspNetCore.Server.Kestrel.Core StackTrace: at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.CreateResponseHeader(Boolean appCompleted) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.ProduceStart(Boolean appCompleted) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.InitializeResponseAsync(Int32 firstWriteByteCount) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.WriteAsync(ReadOnlyMemory`1 data, CancellationToken cancellationToken) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpResponseStream.WriteAsync(Byte[] buffer, Int32 offset, Int32 count, CancellationToken cancellationToken) at Microsoft.AspNetCore.Http.HttpResponseWritingExtensions.WriteAsync(HttpResponse response, String text, Encoding encoding, CancellationToken cancellationToken) at Microsoft.AspNetCore.Http.HttpResponseWritingExtensions.WriteAsync(HttpResponse response, String text, CancellationToken cancellationToken)

I am having the same issue. However, I cannot just target the other SDK, I want a console application. What is the best way to go about this issue in that situation?

Ok, I got that figured out now. I was thrown by the fact that after changing to Sdk.Web instead of Sdk, the project started as a website. It did this because it had automatically added an IISExpress profile. When I switched back to the original profile, it acted as a CLI again.
