.NET9 MAUI sample App build crash on C:\Program Files\dotnet\sdk\9.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(494,7)

[Pipozor]

Describe the bug

Impossible to build MAUI .NET9 default sample project in RELEASE for some (or all?) platforms.

Remark : it was working in DEBUG build (past 3 days) but today not working in DEBUG too!!

To Reproduce

Simply create a new MAUI .NET9 with the sample project checked.
Build in Release for windows/ios/android platforms.

Exception

Further technical details

Visual Studio 17.12.0 or Visual Studio 17.13.0.Preview 1

• I tried to repair Visual Studio installation -> same error
• I reinstalled Visual Studio from scratch -> same error
• I tried to resave the file C:\Program Files\dotnet\sdk\9.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets
  in case of some UTF8 etc... but it is clean and ANSI.

It seems to be more an internal issue!?

• If it helps to analyse : a similar issue raised in May 6th 2024 here

@Redth @jonathanpeppers seen this before?

[jonathanpeppers]

I would guess this file is malformed?

sdk/src/Tasks/Microsoft.NET.Build.Tasks/ResolveRuntimePackAssets.cs

Line 132 in 9083056

var runtimeListPath = Path.Combine(runtimePackRoot, "data", "RuntimeList.xml");

But the error message doesn't contain the file path to easily check. You could handle XmlException and put the file path in the MSBuild error, but maybe that is overkill.

[Redth]

My guess is it's related to: dotnet/maui#25832

[Pipozor]

Thank you for replies.

I uninstalled visual studio, dotnet 8 and 9 SDK.

I don't know if related to the issue, but when :

• I reinstalled Visual Studio 2022 (latest).
• reinstalled Dotnet 8 SDK (dotnet-sdk-8.0.404-win-x64.exe + dotnet-runtime-8.0.11-win-x64.exe)
• dotnet workload update (in admin cmd), I got some failed :

Then :

• I installed dotnet 9 SDK from dotnet-sdk-9.0.100-win-x64.exe + dotnet-runtime-9.0.0-win-x64.exe
• dotnet workload list :

---> A problem appeared in yellow (see screenshot :)

Then, I am doing :

• dotnet workload update

Same issue :(

[Pipozor]

Can Dot8 SDK & Dot9 SDK coexist?

After all actions above when doing:

dotnet workload list

I got only SDK 9 in the list; Like if SDK 8 was gone

I tried some options, but same issues:

With verbose mode detailed:

[Pipozor]

I tried with dotnet workload restore
but same issue :(

I noticed the errors occurs on a randomly, if I launch successive dotnet workload restore...

I tried specific workload_id to install, all failed :

Some more detail with this command dotnet workload repair
It says "installation source of this product is no more available. Verify that source exists and you have access". !!!
