csharp-ls cannot jump to metadata

[razzmatazz]

your lsp-csharp.txt contains this:

 "message": "csharp-ls: msbuildWorkspace.Diagnostics: [Failure] Msbuild failed when processing the file '/home/serezlan/Workspace/csharp/training/SasanaLinkedList/SasanaLinkedList.csproj' with message: /usr/share/dotnet/sdk/5.0.401/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets: (241, 5): The \"ResolvePackageAssets\" task failed unexpectedly.\nNuGet.Packaging.Core.PackagingException: Unable to find fallback package folder '/usr/share/dotnet/sdk/NuGetFallbackFolder'.\n   at NuGet.Packaging.FallbackPackagePathResolver..ctor(String userPackageFolder, IEnumerable`1 fallbackPackageFolders)\n   at Microsoft.NET.Build.Tasks.NuGetPackageResolver..ctor(String userPackageFolder, IEnumerable`1 fallbackPackageFolders)\n   at Microsoft.NET.Build.Tasks.NuGetPackageResolver.CreateResolver(IEnumerable`1 packageFolders)\n   at Microsoft.NET.Build.Tasks.NuGetPackageResolver.CreateResolver(LockFile lockFile)\n   at Microsoft.NET.Build.Tasks.ResolvePackageAssets.CacheWriter..ctor(ResolvePackageAssets task)\n   at Microsoft.NET.Build.Tasks.ResolvePackageAssets.CacheReader.CreateReaderFromDisk(ResolvePackageAssets task, Byte[] settingsHash)\n   at Microsoft.NET.Build.Tasks.ResolvePackageAssets.CacheReader..ctor(ResolvePackageAssets task)\n   at Microsoft.NET.Build.Tasks.ResolvePackageAssets.ReadItemGroups()\n   at Microsoft.NET.Build.Tasks.ResolvePackageAssets.ExecuteCore()\n   at Microsoft.NET.Build.Tasks.TaskBase.Execute()\n   at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()\n   at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(ITaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask)",

some googling points me to:

could you try to deleting bin+obj folders and then run dotnet build again on the directory? and then do M-x lsp-restart-session

are you using mono/older version of dotnet on the same project or maybe jetbrains rider by any chance? maybe thats why msbuild is confused..

OK @razzmatazz
I got it to work on fresh dotnet core project.

The training folder was an old repo back when lsp was not a thing.

Thanks.
