Self contained apps fail to build with AnyCPU & RIDs

[mattleibow]

Describe the bug

When building a self contained app that uses a RID instead of the platform, the build fails:

C:\Users\mattl.nuget\packages\microsoft.windowsappsdk\1.1.1\buildTransitive\Microsoft.WindowsAppSDK.SelfContained.targets(42,5): error : The platform 'AnyCPU' is not supported for Self Contained mode.

@Scottj1s I believe this is similar to another issue before with copying things. I copied the changes you made in the _GetProjectArchitecture target and it works here too.

Steps to reproduce the bug

    <IsUnpackaged>true</IsUnpackaged>
    <WindowsPackageType Condition="'$(IsUnpackaged)' == 'true'">None</WindowsPackageType>
    <WindowsAppSDKSelfContained Condition="'$(IsUnpackaged)' == 'true'">true</WindowsAppSDKSelfContained>
    <SelfContained Condition="'$(IsUnpackaged)' == 'true'">true</SelfContained>

@mattleibow The check needs to include "Any CPU" as well. When building a .sln a .metaproj gets generated that converts "Any CPU" to "AnyCPU" but if you build the .proj file directly this doesn't happen and this check breaks.

This AnyCPU vs Any CPU might affect the other locations as well then? AnyCPU is used a lot in the targets generally.

Yes, there is already another bug I filed here where I am hitting this issue. Would be a good idea to scrub the the whole repo.

Discussion/3026 helped me to solve this issue.
Just add the platform parameter to your command with -p:Platform=....

[mattleibow]

In most modern frameworks - such as maui - we use RIDs. So, it does work with Platform, but I am explicitly not using it.

I added some more workarounds in #893
