`dotnet workload` fails with KeyNotFoundException after updating SDKs

[mstefarov]

Describe the bug

I have VS 17.3 and VSPreview 17.4 installed side-by-side, and I just updated both to latest versions (17.3.5 and 17.4pre2.1). Since the update, my builds started failing with NETSDK1 "missing workload" errors. So I ran dotnet workload restore and it failed with an exception:

PS R:\foo> dotnet workload restore .\src\Foo\Foo.csproj
__________________________________________________
Project "R:\foo\src\Foo\Foo.csproj" (_GetRequiredWorkloads target(s)):

__________________________________________________
Project "R:\foo\src\Foo\Foo.csproj" is building "R:\foo\src\Foo\Foo.csproj" (_GetRequiredWorkloads target(s)):

Done building project "Foo.csproj".
Installing workloads:

Workload installation failed: One or more errors occurred. (The given key 'Microsoft.iOS.Sdk' was not present in the dictionary.)

I ran dotnet workload repair. It claims to have repaired "ios" and "maui" workloads, but my build error and the dotnet-workload exceptions did not go away.

"dotnet workload repair" output

PS R:\foo> dotnet workload repair

Successfully repaired workloads: ios maui

To Reproduce

I'm not sure how to repro this -- perhaps it's a problem with migrating from older VS/dotnet installs.

Exceptions (if any)

When I run dotnet workload list, I got what I suspect is the same error but with more details:

Same issue here. Ver. 17.3.5 and 17.4.0 Preview 2.1. Is there a workaround? I can't develop any further now. Missing workload for specified target framework. Tizen is already deactivated in the project file. Error remains the same. Sorry if this is the wrong place to ask, but I haven't found anything else. Thank you.

[Inux]

@mstefarov : I had the same issue. I have removed all non-maui workloads (e.g sudo dotnet workload uninstall maccatalyst) and just kept the maui ones. Now I can at least build my apps again in the VS Mac Preview.

[marcpopMSFT]

Can you share the results from dotnet --info and can you share the contents of the program files\dotnet\sdk-manifests folder (zip up the folder so we can take a look at the contents)?

[mstefarov]

You can find the output of dotnet --info at the bottom of the issue, in a collapsed block ^

Here is a copy of the manifests folder: sdk-manifests.zip

[radiolondra]

Same issue here after updating VS2022 from 17.3 to latest 17.3.5. Like @AsPaper now I can't develop any further. Hoping someone will give a solution ASAP.

[DonovanAGBR]

I hoped running dotnet workload repair would do the trick; it didn't.

I was able to successfully run dotnet workload uninstall ios, after which I ran dotnet workload restore which finally completed.

[AsPaper]

Super. Thank you very much. That worked for me as well.
I still had the same error message when creating the project, but after restarting visual Studio it worked.
You made my day!

[marcpopMSFT]

Can folks still hitting this run the https://aka.ms/vscollect and provide us the logs? From looking at the code and the manifests provided above (thanks for that), we have a theory. Between August and September releases, we changed the 6.0 workload pack names to include a .net6 text so we could differentiate packs between net6 and net 7. From the manifests provided, the customer still has the August manifests even though they updated to 17.3.5 which should have included the newer manifests.

When you run workload commands, we check to see if there are updates but the pack names changes and that's that exception. @dsplaisted is that exception blocking cause it feels like we need to harden the code for this?

The solution is to get the workload manifests updated to the newer version. Maybe try dotnet workload install ios or maybe clear out the advertising manifest location under %temp% before trying that operation. We're still working on getting a repro now that we have a theory for why this works. Dononvan's solution may work here because it gets you into a state with the correct newer manifest files.

Same issue here. @marcpopMSFT I ran Collect.exe but the log is 52MB. Should I just attach it here?

I hoped running dotnet workload repair would do the trick; it didn't.

I was able to successfully run dotnet workload uninstall ios, after which I ran dotnet workload restore which finally completed.

Thanks, this mostly worked for me too. I had to uninstall some other workloads first too, but running restore let me know each time.

currently it seems that workloads are totally broken and you cannot install any workload anymore. i cant install workload android ios or any other anymore...

workload search only results the following:

if i understood correct this should list all downloadable workloads :(
