Update Workload Problem/ NuGet Package unable to be installed.

Question

**I have created 3 Projects:

1. FrontEndProject and it is a Blazor Project and this is the csProj:**
   <Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

<PropertyGroup>

<TargetFramework>net7.0</TargetFramework>

<Nullable>enable</Nullable>

<ImplicitUsings>enable</ImplicitUsings>
```  </PropertyGroup>

  <ItemGroup>

<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="7.0.16" />

<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="7.0.16" PrivateAssets="all" />

</Project>

**2) TraditionalProject (API Project):**  
<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>

<TargetFramework>net6.0</TargetFramework>

<Nullable>enable</Nullable>

<ImplicitUsings>enable</ImplicitUsings>

  <ItemGroup>

<PackageReference Include="Swashbuckle.AspNetCore" Version="6.5.0" />

</Project>

**3) AspireApplication:**

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>

<OutputType>Exe</OutputType>

<TargetFramework>net8.0</TargetFramework>

<ImplicitUsings>enable</ImplicitUsings>

<Nullable>enable</Nullable>

<IsAspireHost>true</IsAspireHost>

<UserSecretsId>4e304158-cb25-47d7-86fd-457416df5962</UserSecretsId>

  <ItemGroup>

<PackageReference Include="Aspire.Hosting.AppHost" Version="8.0.0-preview.6.24214.1" /> <PackageReference Include="Microsoft.Maui.Graphics" Version="8.0.3" />

</Project>

I am trying to update the workload using this command:  
"dotnet workload update"  
and I am getting this:  
*Workload update failed: One or more errors occurred. (Version 8.0.21 of package microsoft.maui.graphics.win2d.winui.desktop.msi.x64 is not found in NuGet feeds [https://api.nuget.org/v3/index.json;C:\Program]() Files (x86)\Microsoft SDKs\NuGetPackages\".)*  
  
I have tried these approaches:  
1)  dotnet nuget update source nuget.org. then: dotnet nuget locals all --clear  
  
2) installing *microsoft.maui.graphics.win2d.winui.desktop.msi.x64* and I always get this no matter what version I try (I tried them all):  
*Severity Code Description Project File Line Suppression State Details 1) Error Package 'Microsoft.Maui.Graphics.Win2D.WinUI.Desktop.Msi.x64 8.0.7' has a package type 'DotnetPlatform' that is not supported by project 'WeatherApp.Aspire.ServiceDefaults'. 2) Severity Code Description Project File Line Suppression State Details Error NU1213 The package Microsoft.Maui.Graphics.Win2D.WinUI.Desktop.Msi.x64 8.0.7 has a package type DotnetPlatform that is incompatible with this project. WeatherApp.Aspire.ServiceDefaults*  
  
3)Adding this to the itemGroup:  
<FrameworkReference Include="Microsoft.WindowsDesktop.App.Wpf" />  
  
and none of these approaches worked.

Answer 1

Dotnet workload updates update the installed sdks, tools and templates for dotnet. They make no changes to a project file or impact nuget.

your workload update error means you have a bad workload manifest file. In your case one of the Maui manifest files. Repairing a workload can be difficult. But start here:

Note: to fix my update error (it was also related to Maui), I ended up having to delete the offending manifest file and reinstall the workload.

Answer 2

Hi @Muhammad Ghozlan,

One or more errors occurred. (Version 8.0.21 of package microsoft.maui.graphics.win2d.winui.desktop.msi.x64 is not found in NuGet feeds https://api.nuget.org/v3/index.json;C:\Program Files (x86)\Microsoft SDKs\NuGetPackages".)

For this error message, I think you may try:

1. Add nuget.org as source

dotnet nuget add source "https://api.nuget.org/v3/index.json" --name "nuget.org"

1. Verify that this source was added:

dotnet nuget list source

For further updated issue which is related to MAUI error message, I think you can follow the steps in this case.
