Blazor server-side: Accumulated SignalR messages hits IIS 30Mb limit #13470
Describe the bug
When using Server-side blazor and IIS hosting, the IIS 30Mb upload limit is reached after a certain amount of interop messages (I'd guess, around 30Mb :P)
This problem is limited to the use of WebSockets under IIS, if SignalR fallbacks to XHR, there is no problem.
Steps to reproduce the behavior:
The text "Success! bug not reproduced!" appears.
If applicable, add screenshots to help explain your problem.
The problem can also be reproduced with IIS (rather than IIS express).
I have not been able to work around this using the following in web.config:
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise>dotnet --info
Host (useful for support):
.NET Core SDKs installed:
.NET Core runtimes installed:
