INSTALL STEPS:

1. Clean machine: Win11 x64 ENU 24h2
2. Install SDK .NET 9.0.200
3. Apply Feed

REPRO STEPS​:

1. Open cmd, then run dotnet workload install wasm-tools to install wasm-tools, and then open a new cmd and run: dotnet workload list

   

2. create a 9.0 WASM app by cmd: dotnet new blazorwasm

3. Change csproj file: <RunAOTCompilation>True</RunAOTCompilation>

4. Build and run successfully

5. Install SDK 10.0.100-preview.1.25103.13 and apply feed and open a ne cmd and run: dotnet workload list

   

6. Create a 9.0 WASM app by cmd: dotnet new blazorwasm -f net9.0

7. Change csproj file: <RunAOTCompilation>True</RunAOTCompilation>

ACTUAL:
Build the WASM project, it will meet an error:

C:\Program Files\dotnet\sdk\10.0.100-preview.1.25103.13\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1147:
To build this project, the following workloads must be installed: wasm-tools wasm-tools-net9
To install these workloads, run the following command: dotnet workload restore

NOTE:

1. This issue can also repro in .NET 10 wasm project when check AOT option
   

EXPECTED:
wasm-tools workload should still be installed after installing 10.0 Preview 1 SDK

To clarify, are you running dotnet workload install/update after installing the 10 sdk? If not, it's been the case since workloads were created that workloads installed into the 9 SDK aren't recognized by later sdks that get installed.

I have installed wasm-tools with the command "dotnet workload install wasm-tools" before installing SDK 10.0, and it works fine. But after I install SDK 10.0, I can see that wasm-tools has been installed with the command "dotnet workload list", but it doesn't work,
After I manually installed wasm-tools again using the command "dotnet workload wasm-tools", .net10.0 project worked. For .net9.0 project, I need to run "dotnet workload install wasm-tools-net9". Is this expected?
