+		var rid = usesRidGraph ? "win10-x64" : "win-x64";
+		var assetsRoot = Path.Combine(projectDir, $"bin/{config}/{framework}-windows10.0.19041.0/{rid}/AppPackages/{name}_1.0.0.1_Test");


The reverted path logic uses different RID values (win10-x64 vs win-x64) depending on the usesRidGraph parameter. This logic is simpler than the original WindowsAppSDK 1.8 version but should be verified to ensure it correctly locates assets for both DotNetCurrent (net10.0, usesRidGraph=false) and DotNetPrevious (net9.0, usesRidGraph=true) test cases.

eng/devices/windows.cake

 	var currentUserMyStore = new X509Store("My", StoreLocation.CurrentUser);
 	currentUserMyStore.Open(OpenFlags.ReadWrite);
 	certificateThumbprint = localTrustedPeopleStore.Certificates.FirstOrDefault(c => c.Subject.Contains(certCN))?.Thumbprint;
+	Information("Cert thumbprint: " + certificateThumbprint ?? "null");


The null-coalescing operator has incorrect precedence here. Due to operator precedence, this evaluates as Information((\"Cert thumbprint: \" + certificateThumbprint) ?? \"null\") which will never use the "null" fallback since string concatenation with null produces a string. Should be Information(\"Cert thumbprint: \" + (certificateThumbprint ?? \"null\")) to correctly display "null" when certificateThumbprint is null.

Suggested change

Information("Cert thumbprint: " + certificateThumbprint ?? "null");

Information("Cert thumbprint: " + (certificateThumbprint ?? "null"));

WindowsAppSDK 1.7 goes out of support on March 18. Is there a timeline for when WindowsAppSDK 1.8 will be included in .NET MAUI?

MartyIX · 2026-01-20T09:26:51Z

What was wrong with WinAppSDK 1.8, if I may ask?

bdovaz · 2026-01-28T07:20:39Z

I have the same questions. Can you answer us, @PureWeen? Thank you.

lothrop · 2026-02-04T10:34:59Z

Looks like there's a new PR #33850 but it's an update from 1.8.3 to 1.8.4?

bdovaz · 2026-02-04T10:43:22Z

Okay, I understand what's happening. If you look at the PR we're on, @lothrop, it reverts on release/10.0.1xx-sr3 branch, but on the main branch it is updated to 1.8.

maui/eng/Versions.props

Line 72 in 1db8161

    
           <MicrosoftWindowsAppSDKPackageVersion>1.8.251106002</MicrosoftWindowsAppSDKPackageVersion>

So I imagine that at some point there will be a release updating to 1.8, but we don't know when. @PureWeen?

MartyIX · 2026-02-04T10:49:06Z

So I imagine that at some point there will be a release updating to 1.8, but we don't know when. @PureWeen?

main is used to branch a service release (SR) branch every month, so unless there is a change (i.e. revert), the 1.8 will be released in the next SR.
