Compiler Error ASPIRE008

Version introduced: 8.2.3

The Aspire workload that this project depends on is now deprecated.

This error appears when a project uses a version of Aspire that relies on the SDK workload, which is now deprecated. The error guides you to migrate your project to a supported version of Aspire that uses the SDK approach instead of the workload.

Example

The following AppHost project file uses the deprecated Aspire workload:

C# project file

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <IsAspireHost>true</IsAspireHost>
    <UserSecretsId>98048c9c-bf28-46ba-a98e-63767ee5e3a8</UserSecretsId>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Aspire.Hosting.AppHost" Version="8.2.2" />
  </ItemGroup>

</Project>

For more information on the Aspire SDK, see Aspire SDK.

To correct this error

Follow the migration guide at https://aka.ms/aspire/update-to-sdk to upgrade your project to a supported version of Aspire that uses the SDK approach.

The migration typically involves:

1. Updating your AppHost project file to use the Aspire.AppHost.Sdk.
2. Removing references to the deprecated workload.
3. Updating package references to supported versions.

Suppress the error

Perigo

Suppressing this error isn’t recommended, as it leaves your project depending on an unsupported version of Aspire.

If you need to temporarily suppress this error, add the following property to your project file:

C# project file

<PropertyGroup>
  <SuppressAspireWorkloadDeprecationError>true</SuppressAspireWorkloadDeprecationError>
</PropertyGroup>
