Running on Windows 10, and the Blazor Server app is using Kestrel. I tried using IIS Express for the Blazor app but it does not run, so not sure what the issue is.
400 error when hosted on Azure?
We have a legacy WebForms app and Blazor Server front-end using Cocoon successfully for a year. It's hosted on our own servers at present and its working perfectly.
Problem
I'm trying to port the same code to be hosted on Azure. I've set up two App Services running in the same service plan (both as Windows hosts). One is running the WebForm app (on .NET Framework 4.8) and the other running Blazor (on .NET 6).
Both apps are up and running independently, but if I try to access a Cocoon page from the Blazor app, it returns a 400 error.
This is the case even if I try to request a static resource, e.g. /img/Test.jpg. This exists on the WebForm app, but it fails and returns a 400 error. From the Blazor site log (below) I can see that it Initially tries to request the /facadeauth route on the target, even though it's accessing a static file, which returns a 401 error. I can query the URL on the webform site, e.g. https://webform-site-url/img/Test.jpg and it works.

GitHub Action for PR is failing with missing VS 2019 installation
I updated a pull request #27 to update the YARP library to version 1.0.1 (to include security fix). The GitHub Action to build the PR is failing when trying to execute a VS2019 build:
https://github.com/VisualReCode/Cocoon/runs/6097402981?check_suite_focus=true#step:8:1
Bug: BlazorRouteDiscovery does not support multiple Route attributes
Blazor supports components with multiple @page directives (see docs).
The BlazorRouteDiscovery class only supports a single RouteAttribute and thus throws an exception if more than one is defined.
Problems when deploying the legacy app as a subsite
Hello!
loving this package so far, i'm trying to rewrite a legacy webforms app using blazor server.
However i'm having some problems when deploying the apps.
The legacy app is deployed as a subsite, so for example: https://legacyapp.domain.com/subsite
in the appsettings.json of the blazor app i've correctly set the urls using https://legacyapp.domain.com/subsite as destinationPrefix.
In this situation the proxy doesn't seem to work, i get correctly redirected to https://legacyapp.domain.com/subsite when opening the blazor app, but after authenticating i'm not redirected back to the blazor app, whereas while debugging locally everything works as expected.
I'm guessing is has to do with the legacy app being deployed as a subsite but i'm actually not sure.
Where i get redirected for authentication the return url is https://legacyapp.domain.com/subsite/Account/Login?redirecturl=~/ which obviously cannot work... i tried manually setting the redirect url to the url of the deployed blazor app but that doesn't work too, after auth i'm redirected to the legacy app.
How should i approach this situation?
Many thanks
Long HTTP requests causes YARP to Timeout
Hello!
I am currently testing this library to allow an incremental migration of a BIG Webforms application (>160 pages) to Blazor server.
First tests seem to run apparently fine however some pages take a very good while to load in the web forms app (we're talking about 2-5 minutes just to load) which causes YARP to fail miserably.
Here is a Pastebin for all intents and purposes: https://pastebin.com/cHHkbv9m
Now the question is, how should I go about appropriately handling the timeout value using this Library?
Security bug
I think I've found a nasty security-related bug. What's the best way to disclose this without publicly posting it?
Wrong routing when component implements class based on ComponentBase
Hello!
I'm trying to rewrite a legacy webforms app using Blazor server.
However, I'm having some problems with proxy routing.
Let's imagine ComponentBase class implementation such as this one:
public class CancellableComponent : ComponentBase, IDisposable
{
internal CancellationTokenSource _cts = new();
public void Dispose()
{
_cts.Cancel();
_cts.Dispose();
}
}
and the component that is implementing it
@page "/Settings"
@implements CancellableComponent
...
Then routing is strange, when I hit URL (for example https://localhost:5001/Settings) directly, it is not routed to Blazor page, but to the original webforms page. But when I click on its tab in the menu (Blazor part) it is routed correctly. Of course, when I remove @implements CancellableComponent from Blazor page, routing is correct in any circumstances.
How should I approach this situation, is there any chance of implementing my custom component base and having correct routing?
Many thanks

Bug: Unexpected msgpack code 13 (positive fixint) encountered
Running with Blazor Server on .NET 6, if a user is not logged on we get this exception in the Blazor app's log:
[17:23:30 ERR] Failed to deserialize ReCode.Cocoon.Proxy.Authentication.MessagePrincipal value.
MessagePack.MessagePackSerializationException: Failed to deserialize ReCode.Cocoon.Proxy.Authentication.MessagePrincipal value.

[17:23:30 INF] Cocoon was not authenticated. Failure message: Failed to deserialize ReCode.Cocoon.Proxy.Authentication.MessagePrincipal value.
Looking at the code in CocoonAuthenticationClient,cs, it logs the response and status code, which we see in the Blazor log just before the exception:
[17:23:29 INF] Start processing HTTP request GET http://localhost:9343/facadeauth
[17:23:29 INF] Sending HTTP request GET http://localhost:9343/facadeauth

[17:23:30 INF] End processing HTTP request after 478.5473ms - 200
Note the 200 response code.
Looking at AuthApiHandler.cs in Cocoon.Legacy it should return a 401 if not logged in, however that does not seem to be happening.
