[WA] No Server with .NET 5 Deployment

RickJ · January 18, 2021, 11:38pm

Hello everyone, I'm testing the 15 days trial with the Radzen-Tool before I buy, the tool looks awesome so far (did watch ALL of the videos). But if I try to deploy an application with .NET 5, the ZIP-File does not contain any server files, even if the console says "Copying server app to deploy folder" without any errors. The ZIP file does have the same files as the "\server\bin\Release\net5.0\publish" folder, which are:

publish (empty folder)
ref\RadzenBlazerWa3.Client.dll
wwwroot_framework*.* (all the files)
appsettings.json
RadzenBlazerWa3.Client.*
web.config

In the folder "\server\bin\Release\net5.0" there are the server files (like "RadzenBlazerWa3.Server.exe"), if I try to start the server, everything looks fine (in the console), but if I try to access the web page, it redirects me to the SSL Port (5001) und there I get a 404 error. I can't reproduce the other error, but I got something like "digest" and "sha256" error.

The dev run worked fine so far and with .NET Core I can create the correct deployment. In all cases I used the default settings and used the same database (the example database from the CRM Tutorial), so nothing special at all.

Hi @RickJ,

Not sure why there are no server related files in your zip - usually looks like this:

RickJ · January 19, 2021, 1:51pm

All my other builds looks exactly the same. But this looks like so:

This is what I did so far:

Updated VS 2019 to the latest version
Installed the latest Radzen
Installed the .NET files via the Radzen Tool
Tested a .NET 5 WA Project within VS 2019 (everything ok)
Created different projects (everything ok)
Created projects with .NET 5 WA, no server files

Seems this also happens with my .NET 5 WA projects without any datasources, just an empty index page.
What can I do?

If I deploy it via Visual Studio, the server files will be generated, but when I open the website I will be forwarded to the SSL Port (5001) and get this error:
Failed to find a valid digest in the 'integrity' attribute for resource 'https://localhost:5001/_framework/dotnet.wasm' with computed SHA-256 integrity '47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU='. The resource has been blocked.

I need to test the basics before becoming a costumer.

All errors:

If I disable the integrity check, I get these errors:

I have no more ideas atm...

Have you upgraded your app manually (updated the project references) from .NET 3.1 to .NET 5?

RickJ · January 20, 2021, 5:13pm

No, I created a brand new Blazor WebAssembly Project (in Radzen) with .NET 5 selected, just added an empty page (with a title). Before that I created Angular, Blazor ServerSide and Blazor WA project with .NET Core and .NET 5 (all at the same time), deployed all and just the Blazor WA with .NET 5 have these problems. A new Blazor WA with .NET 5 in VisualStudio also worked fine. I mean the missing files are just a part of the problem, I could live with deploying via VS, if that worked.

RickJ · January 21, 2021, 7:14pm

It seems like it has something to do with the generated project files and the cache (which means the cache can maybe hold the "good" files from a working project).
After a few reboots I did get it to work again, so to reproduce I invested days now, this is how I can reproduce it:

Create a new Blazor WA (with .NET 5) project
Add (empty) Index page
Run the app
Deploy it to a folder (via Radzen)
=> The server files are missing
Now I publish via VS
The server files are there, but when I run the app,I get the integrity error
Failed to find a valid digest in the 'integrity' attribute for resource 'https://localhost:5001/_framework/dotnet.wasm' with computed SHA-256 integrity '47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU='. The resource has been blocked.
Close Radzen

Now the error:

Create a new Blazor WA (with .NET 5) project
Add (empty) Index page
Run the app
Deploy it to a folder
Server files are missing like before
Now deploy it via VS
Open the deployed App
Go to the Dev-Tools with F12 (Chrome for example) Clear site data (F12 -> Application) and then hard refresh the site
Now the integrity error comes in the console (or maybe right after start)
Failed to find a valid digest in the 'integrity' attribute for resource 'https://localhost:5001/_framework/dotnet.wasm' with computed SHA-256 integrity '47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU='. The resource has been blocked.
Whatever I do (including multiple reboots, new projects, new deployments), I always get the error

The only way how it works for me is this:

Create a new Blazor WA (with .NET 5) project
Add (empty) Index page
Deploy it via VS

I use VS 2019, if I look at the generated solution files, there is maybe one of the errors.

There is also a other problem, after a few deploy tests, I can't set the user and password in the IIS Deploy settings anymore, but I don't want to waste more time for this, I will try it via VS for now.

Based on the files you are showing it looks like you are deploying/publishing the Client app. You need the server app and would publish that. If you are using the "Blazor Wasm with ASPNET Hosted" then you'd publish the server (aspnet) app. THe client app would come with it as it is referenced.

RickJ · January 22, 2021, 1:25pm

I'm using the Radzen Deploy function, you can't choose client/server there. Via VisualStudio I always deploy via the server project.
