The current release process pushes all the packages at the same time. This is an issue since the template package needs to be updated with the latest version which is pushed at the same time. There should be a step to update the template with the latest version of the newly released package before releasing the template.
to work around this you can run dotnet add package BytecodeAlliance.Componentize.DotNet.Wasm.SDK --prerelease to upgade the package for now.
