Can't reference package nightly build in project with EnableSdkContainerSupport

[flcdrg]

In a project with EnableSdkContainerSupport property set (eg. when created with the Visual Studio Publish wizard), you can't then add a package reference to the nightly build. It fails with the following error:

info : Restoring packages for C:\dev\sandbox\WebApplication10\WebApplication10\WebApplication10.csproj...
info : Package 'Microsoft.NET.Build.Containers' is compatible with all the specified frameworks in project 'C:\dev\sandbox\WebApplication10\WebApplication10\WebApplication10.csproj'.
error: Error while performing Update for package 'Microsoft.NET.Build.Containers'. Cannot edit items in imported files -
error:   Item 'PackageReference' for 'Microsoft.NET.Build.Containers' in Imported file 'C:\Program Files\dotnet\sdk\7.0.200-preview.22628.1\Sdks\Microsoft.NET.Sdk.Web\Sdk\Sdk.props'.

Not sure if this is something that can be fixed, or just will need to be documented to either comment out the property or set it to false.

This is definitely not the intended experience - will chat with the team and see if we can squeak in a change for the 7.0.2xx series here. Otherwise you may need to workaround by setting EnableSdkContainerSupport to false. This will definitely be solved by the time we integrate into the SDK properly for 7.0.3xx, though.

@vijayrkn - heads up that users can't float the versions like we thought.

For the package reference issue, if you change the include to update, does it work?
<PackageReference Update=

You could also change the version reference with a property

<SdkContainerSupportPackageVersion>0.3.2</SdkContainerSupportPackageVersion>

We should definitely call this out very explicitly in the blog post @baronfel.

Closing this because it's been covered.
