The type or namespace name 'Maui' does not exist in the namespace 'Prism' (are you missing an assembly reference?)

[Corneloues]

I cannot get my MAUI project to detect Prism.Maui. I've tried uninstalling/re-installing, cleaning/rebuilding, etc.

This has stumped me for hours now...

The type or namespace name 'Maui' does not exist in the namespace 'Prism' (are you missing an assembly reference?)

  <ItemGroup>
    <PackageReference Include="Prism.Maui" Version="9.0.537" />
    <PackageReference Include="Prism.DryIoc.Maui" Version="9.0.537" />
    <PackageReference Include="Microsoft.Maui.Controls" Version="9.0.90" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="9.0.7" />
  </ItemGroup>

		<TargetFrameworks>net9.0-android;net9.0-ios;net9.0-maccatalyst</TargetFrameworks>
		<TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net9.0-windows10.0.19041.0</TargetFrameworks>

		<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">15.0</SupportedOSPlatformVersion>
		<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">15.0</SupportedOSPlatformVersion>
		<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">21.0</SupportedOSPlatformVersion>
		<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</SupportedOSPlatformVersion>
		<TargetPlatformMinVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</TargetPlatformMinVersion>
		<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tizen'">6.5</SupportedOSPlatformVersion>

I really don't know what I am doing wrong...

This is one project in a larger solution and the only project that is using PRISM. And this is only one of two projects in the solution that are MAUI.

Any help would be appreciated.

Cheers,
