kandi X-RAY | r-wasm Summary

r-wasm is a R library typically used in Utilities, Build Tool applications. r-wasm has no vulnerabilities and it has low support. However r-wasm has 701 bugs. You can download it from GitHub.

For this document, install ATLAS CBLAS/LAPACK. You could compile your own CBLAS/CLAPACK. Download F2Clib from We need f2clib(the library), make a folder and unzip this file inside the folder (else you'll clutter your workspace). R was downloaded from the R website. Read README in f2clib. For hala[1], i had to run. (see the README file in that folder). This is important else all R calls to fortran result in segfaults of random errors. ALSO compile with CFLAGS=-fPIC (by editing makefile.u and saving as Makefile).

Use serilog as logging provider in blazor webassembly client app

Asked 2022-Mar-31 at 10:10

I'd like to use serilog in a blazor webassembly net 6 app, both on client and server sides. In this article I found out how to relay log entries to server so that they are written in log files.

In this approach however the Log static class is used to explicitly add log entries.

Blazor Client - error NETSDK1082: 'browser-wasm'

Asked 2021-Dec-04 at 05:53

I created a simple blazor wa project hosted option selected. In the client side of the project in the project it automatically comes with . I then added a few nuget packages before writing any code and when I clean the solution and even rebuild the solution it gives me the error:

error NETSDK1082: There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'.

I looked it up and saw that one solution to this is to change the first line in the .csproj to instead of what it comes with by default. I did so but then when I run just the client it says 404. Then if I remove the extra packages and put it back to the default sdk it works. Is there a reason why I am getting this error with those packages? I created a blazor wa hosted .net 6 project btw.

Answered 2021-Dec-04 at 05:53

Not just .csproject but also check project.assets.json . Usually the culprit is the non web assembly compatible packages. The easier way is to check your NuGet dependencies and verify if your third party packages are compatible with WebAssembly

QUESTION

Locating my static assets when publishing on Azure with Blazor WebAssembly

Asked 2021-Nov-25 at 09:26

I have a Blazor WebAssembly (Core Hosted) solution for testing purpose. I test 2 different scenario:

1st one: publishing the server side on Azure and the client side inside a storage account.
2nd one: publishing everything on Azure

FYI my solution is composed of 3 projects

Client
Server
Shared (Razor Class Library) <-- with some Blazor components + css + js + ...

The 1st scenario

For publishing the server side: right click on the Server project then choose Publish, then choose Azure (fill in settings,...) then start the publishing process.

For publishing the client side: right click on the Client project then choose Publish, then choose Folder, then start the publishing process. Next, I used the Microsoft Azure Storage Explorer app to upload files (located in \bin\Release\net5.0\browser-wasm\publish\wwwroot\ ) inside the storage account.

I clearly see that:

my static assets (css, js, ...) are inside \wwwroot\ _content\
my dll files (Prolog.Client.dll, Prolog.Shared.dll among many others) are inside \wwwroot\ _framework

And everything is working as expected.

The 2nd scenario

For publishing everything on Azure, simply right click on the Server project then choose Publish, then choose Azure (fill in settings,...) then start the publishing process.

Everything is working as expected.

Thanks to the kudu website (https:// myappxxx. scm .azurewebsites.net/) I can browse files on my server. I easily located my dll files inside the wwwroot folder on the server (Prolog.Client.dll, Prolog.Server.dll, Prolog.Shared.dll among many others).

But what is obscure to me is to know where are physically located my static assets ? Where are my css and js files ?

Can I use the Kudu website to browse through folders to find them ?

For example, below, my javascript file named main.js. I tried to use the Kudu website to locate it on my server where it has been published without luck. I don't find any _content folder nor Prolog.Shared folder.

UPDATE

Thanks to Mister Magoo : I tried the "App Service Editor (Preview)" under the "Development Tools" section of the Azure Portal for my App Service. From there I was able to browse through all my files, including my static assets. It was pretty similar to the Kudu console... except that in my Kudu console some files and folders were missing. I noticed a warning message in my Kudu console:

So I added this key in my Local Storage and bingo! All my missing files were suddenly visible. Problem solved.

Blazor Webassembly error when adding a ASP.NET Core Web API Project Reference

Asked 2021-Sep-30 at 17:59

I created two fresh new projects a Blazor Web Assembly without checking the option of ASP.NET Core hosted because I did not want to create the other two projects that get created. Followed by a fresh new ASP.NET Core Web API project. After creating this project and writing any code, I added a few nuget packages to my web api project that I plan on using. I then expanded the Blazor Web Assembly project and right clicked on Dependencies, clicked on Add Project Reference and selected my Web API project. Then when building both projects, the web api passes and the blazor web assembly fails because of Error NETSDK1082. The exact error is shown below.

C:\Program Files\dotnet\sdk\6.0.100-preview.3.21202.5\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(391,5): error NETSDK1082: There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'.

I looked up online for that error and attempted the solution where I add two lines of code into my .csproj file inbetween the section, but even after adding this it failed. I even deleted the obj folder and rebuilt the blazor project but it produced the same error.

Update: It seems you were trying to add a reference to the Web API to the blazor web assembly (WA) project. You do not need to do that. There are two WA models:

.net core hosted: You can create this type of project by ticking the ".net core" hosted when creating your WA project. It creates three projects by default. Client, server (mostly API controllers) and shared. Client and server both refer to the shared project. The shared project has all the classes that both WA application and controllers in server.
Standalone: In this case, you get two projects. Note that you can add another shared project like in (1) above to use classes that both can use. However, in this case the API controller need not even know it is talking to a blazor app.

You see the 'browser-wasm' error because of nuget packages that are incompatible with blazor wasm. You got the error because you added the server project reference to the WA project.

Read more here

If cleanly opting for (1) or (2) does not work, search for project.assets.json in your project folder and search the section with browser-wasm. Check the list of packages in that section and try uninstalling those nuget packages one by one.

Unable to host Blazor application

Asked 2021-Aug-15 at 21:44

I am unable to get a Blazor app working while hosting the application as an IIS application on my local Windows 10 machine. The app is very simple, with just one page with minimal components - even simpler than the default Blazor app provided.

These are my steps:

Click on publish app
Select Folder, note it's going to ...\bin\Release\net5.0\browser-wasm\publish\
Open IIS, navigate to Default Web Site
Right-click Default Web Site and select Add Application
Select physical path as the path above, and host at www.NAME.com
Click Browse.. to view the app at www.NAME.com on *:80
Page displayed is the welcome page of IIS

Attempted Solution 1: Install URL Rewrite

Attempted Solution 2: Go to Hosts (in System32) and tried adding 127.0.0.1 or 127.0.0.1::80 followed by www.NAME.com

Attempted Solution 3: In index.html, edit the base element to include the link

Attempted Solution 4: Instead of adding an application under Default Website in IIS, add it as a website instead

Attempted Solution 5: Gave IIS_IUSRS full permissions to web.config (Image)

None of the attempted solutions worked. I just started using Blazor yesterday and I am very new to this. Am I doing something wrong? Thank you!

Please refer to this tutorial, I think is one of the best tutorial to achieve your goals: https://blog.medhat.ca/2020/08/deploy-client-side-blazor-web-api-to.html?m=1

Remember that the configuration of the hostname in your hosts file is related to your machine only

So, in order to allow the students to access your IIS published site you need:

Register a hostname in a DNS server that all the computer of the students will use to resolve your machine name. I.e. if your machine should be accessible with www.name.com you need your DNS server resolves this name with your local IP address
To use the https protocol you need a certificate on your local machine, loaded in your IIS configuration, but the same certificate has to be available to every computer of your students.

I think the better and simpler solution is to use your local machine name, probably using your full DNS name, and allows the students to access the site using this name on their browser.

In this case you can use your local development certificate to allow https connection This certificate is already installed on your machine for development purpose.

Every concept I've described is well documented on the web and here on the SO.

Cannot Migrate Blazor App to .Net 5 Due to System.Runtime Error

Asked 2021-Jun-08 at 13:35

I have been working through an awesome tutorial within Udemy to learn more about Blazor (https://www.udemy.com/course/programming-in-blazor-aspnet-core/), but have hit a stumbling block that I'm not entirely sure what to do with.

Short Version

When upgrading to .Net 5 from .Net Standard 2.1, I end up with this error when trying to run this sample Blazor application as soon as it loads up (so it's not hitting any of my code): System.TypeLoadException: Could not resolve type with token 01000014 from typeref (expected class 'System.Threading.Tasks.Task' in assembly 'System.Runtime, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a') I see a similar problem with this SO link, but it didn't really give me much to go off of.

Detailed Version

With prior versions of .Net, you installed the latest, then Visual Studio picked that up, you switched projects and away you went - everything was seamless and just worked. With some of the newer stuff though, Microsoft's messaging has been extremely confusing and the problem I'm hitting now is inside that Udemy tutorial I need to utilize the IJSObjectReference interface to do something. When I first added that to the code, the type reference couldn't be resolved so a quick search pointed me to needing to move the project to .Net 5 by changing this:
