I'm trying to run dotnet workload install microsoft-net-sdk-blazorwebassembly-aot from my Dockerfile while building my Blazor project in order to enable AOT WASM compilation.
Here is the relevant Dockerfile code:
FROM mcr.microsoft.com/dotnet/sdk:6.0-focal-amd64 AS builder
...
RUN dotnet workload install microsoft-net-sdk-blazorwebassembly-aot
RUN dotnet publish -c Release
However, this fails with an error like:

Updated advertising manifest microsoft.net.sdk.maccatalyst.
Updated advertising manifest microsoft.net.sdk.macos.
Updated advertising manifest microsoft.net.workload.mono.toolchain.

I also tried with --skip-manifest, and this appears to install the workload, but then fails to perform the AOT build.
RUN dotnet workload install microsoft-net-sdk-blazorwebassembly-aot --skip-manifest-update

Any advice?
Morgan, you're hitting two issues:
On the skip-manifest (which is the workaround) is issue https://github.com/dotnet/sdk/issues/18450
The emcc --version error is issue https://github.com/dotnet/runtime/issues/54342 and resolved by installing Python first...see example: https://github.com/timheuer/PictureFixer/blob/docker/PictureFixer/Dockerfile#L11-L12 (on docker branch in the repo)
You will then hit a different bug (could not find cross compiler) which is issue https://github.com/dotnet/runtime/pull/54651 (which has been checked in).
Once #3 is fixed in an image you can consume, it should work ensuring you add #2 in your script. Example full Docker file:
FROM mcr.microsoft.com/dotnet/nightly/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
#FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
FROM mcr.microsoft.com/dotnet/nightly/sdk:6.0 AS build
COPY ["nuget.config", "nuget.config"]
RUN apt-get update
RUN apt-get install --no-install-recommends --yes python3
RUN dotnet workload install microsoft-net-sdk-blazorwebassembly-aot --skip-manifest-update
WORKDIR /src
COPY ["Server/PictureFixer.Server.csproj", "Server/"]
COPY ["Shared/PictureFixer.Shared.csproj", "Shared/"]
COPY ["Client/PictureFixer.Client.csproj", "Client/"]
RUN dotnet restore "Server/PictureFixer.Server.csproj"
COPY . .
WORKDIR "/src/Server"
RUN dotnet build "PictureFixer.Server.csproj" -c Release -o /app/build --nologo
FROM build AS publish
RUN dotnet publish "PictureFixer.Server.csproj" -c Release -o /app/publish --nologo
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "PictureFixer.Server.dll"]
You can temporarily work around #3 by adding this to your Blazor Wasm project csproj:
<PropertyGroup>
<_MonoAotCrossCompilerPath>#(MonoAotCrossCompiler->WithMetadataValue('RuntimeIdentifier','browser-wasm'))</_MonoAotCrossCompilerPath>
</PropertyGroup>

I am new to docker and AKS, I am working on a .Net project that is migrated from .Net core 3.1 to .Net 6 , I am trying to containerize and deploy to AKS. First i wanted to test in the local machine so i had setup docker in the macbook m1 and followed this link https://learn.microsoft.com/en-us/visualstudio/mac/docker-quickstart?view=vsmac-2022 to create a dockerfile, I am able to run the dockerfile from Visual Studio if i follow the steps given in the link but if i run docker compose command from terminal i am getting issues with SDK version, however what i am trying to achieve is remove the build stage and directly run the .net application as the build stage is taken care by Jenkins and the DLL is placed in a folder
Here is the complete dockerfile with all the stages
FROM mcr.microsoft.com/dotnet/core/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM mcr.microsoft.com/dotnet/core/sdk:6.0 AS build
WORKDIR /src
COPY DockerDemo/DockerDemo.csproj DockerDemo/
RUN dotnet restore "DockerDemo/DockerDemo.csproj"
COPY . .
WORKDIR "/src/DockerDemo"
RUN dotnet build "DockerDemo.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "DockerDemo.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "DockerDemo.dll"]
I modified dockerfile excluding build stage, I am taking DLL file from a "lib/net6.0" that is built by jenkins and placed in this folder
FROM mcr.microsoft.com/dotnet/core/aspnet:6.0 AS base
COPY ["lib/net6.0","/src/"]
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM base as final
WORKDIR /app
COPY --from=base /src/ .
ENTRYPOINT["dotnet","DockerDemo.dll"]
If i build the dockerfile the image is getting created but when i run I am getting following error
unhandled exception system.io.filenotfoundexception could not load
file or assembly 'NLog, Version=.5.0.0.0
The project is using NLog.Web.ASPNetCore 5.1.4 version, i tried downgrading it to 5.0.0 but i am still getting the same error, i also tried adding just NLog 5.0.0 package but no luck
As i said i am new to Docker and also to the .net development on macbook
My Questions
Q1) Is it possible to exclude the build stage in dockerfile and directly run
Q2) Does the macbook m1 completely supports .Net Core and .Net 6 development so that it can be deployed to AKS via Jenkins pipeline
I want to deploy my Blazor Webassambly App to a Docker Container to run it on my synology NAS.
So my problem is now, that since I want to run my Webassembly App in my VisualStudio IDE with Docker, I have an error "The library 'hostpolicy.dll' required to execute the application was not found in ..."
Has anyone an idea what i could do do solve this error?
Here is the full console output:

If you're using a private nuget feed, try changing the "RUN dotnet restore..." command.
Example:
RUN dotnet restore -s "https://your-nuget-feed.example.com/nuget" -s "https://api.nuget.org/v3/index.json" "Jordan_Webapp_Client/Jordan_Webapp_Client.csproj"
I have been trying to get docker to pull from a private nuget feed which is hosted within Azure Devops, but I consistently get a 401 unauthorized error. I have looked a numerous other answers and resources, but all of which have not helped. My dockerfile script is the following

The error I get from Visual Studio is the following

From what I can tell in the link below; my dockerfile script should work
https://github.com/dotnet/dotnet-docker/blob/master/documentation/scenarios/nuget-credentials.md#using-the-azure-artifact-credential-provider
To ensure it wasn't an issue with the PAT of the user not having access, I gave them access to everything across the whole entire organisation. Any help would be greatly appreciated!
Note #1: My current suspicion is that there are some additional parameters I might need to pass, since the private nuget feed is for a project rather than the entire organisation?
Note #2: I ran the following PowerShell command (https://learn.microsoft.com/en-us/azure/devops/artifacts/tutorials/private-powershell-library?view=azure-devops#package-and-publish-the-module) which worked fine, so I am even more confused to why my dockerfile script does not work.
nuget sources Add -Name "PowershellModules" -Source "https://pkgs.dev.azure.com/<org_name>/_packaging/<feed_name>/nuget/v3/index.json" -username "<user_name>" -password "<personal_access_token(PAT)>"
You can check out below workarounds without using NuGet credential plugin.
1, Use dotnet cli to add credentials to the nuget source in your docker file. And then pass the $PAT in the build arguments (ie. --build-arg PAT=$PAT ):
ARG PAT
COPY . .
RUN dotnet nuget add source "your-source-url" --name "source-name" --username "useless" --password "$PAT" --store-password-in-clear-text
RUN dotnet restore
2, You can also try adding the credentials to the config file using the nuget command. And include the nuget.config which has the credentials in the build context. And copy the nuget.config in your docker file . See below:
sources Add -Name "MyPackages" -Source "https://my.pkgs.visualstudio.com/_packaging/MyPackages/nuget/v3/index.json" -username any -password $PAT -ConfigFile Source/Nuget.config -StorePasswordInClearText
Copy the nuget.config in the docker file, You can delete the nuget.config file when the restore is complete:
COPY *.csproj .
COPY ./nuget.config .
RUN dotnet restore
RUN rm nuget.config
You can refer to my answer to this similar thread that using azure nuget feed in the docker container in Azure pipelines.
I have a .NET Core 3.1 console app that uses the Microsoft.NET.Sdk.WindowsDesktop project SDK because it references Geometry3D in System.Windows.Media.Media3D.
I would like to run this in a Docker container on Windows Nano Server, but I receive the following error when executing docker run:
It was not possible to find any compatible framework version
The framework 'Microsoft.WindowsDesktop.App', version '3.1.0' was not found.
- No frameworks were found.
You can resolve the problem by installing the specified framework and/or SDK.
The specified framework can be found at:
- https://aka.ms/dotnet-core-applaunch?framework=Microsoft.WindowsDesktop.App&framework_version=3.1.0&arch=x64&rid=win10-x64
How do I go about installing the required sdk and runtime?
Here is my existing Dockerfile:
FROM mcr.microsoft.com/dotnet/core/runtime:3.1-nanoserver-1903 AS base
WORKDIR /app
FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1903 AS build

COPY . .
WORKDIR "/src/HelloWpfCore"

RUN dotnet publish "HelloWpfCore.csproj" -c Release -o /app/publish

WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "HelloWpfCore.dll"]
GitHub repo is here: https://github.com/tonysneed/hello-netcore-wpf-nano
I figured it out. I created an image that installs the Windows Desktop runtime on Nano Server base image.

I've only seen that error when attempting to run dotnet run with an already published project (which you do seem to be working with an already published project). Instead, you should simply do dotnet MyProject.dll (no run).
The issue fix by using docker-compose.yml up
