Received response for /v2/getcodeactions but could not find request.

Steps to reproduce

first case:

1. disable Use Modern Net
2. reload omnisharp
3. get first Part omnisharp log, is OmniSharp.MSBuild.ProjectManager Attempted to update project that is not loadedr.

1.enable Use Modern Net
2.reload omnisharp
3. get second Part omnisharp log, is Microsoft.CSharp.CurrentVersion.targets(129,9): Error: 找不到規則集檔案 "ManagedMinimumRules.ruleset"。
4. go to controller type something will omnisharp will report Received response for /findusages but could not find request. and Received response for /v2/getcodeactions but could not find request.

Expected behavior

success load project IntelliSense and highlight is working

Actual behavior

My project is .Net framework v4.6.1, So I think I should be disable UseModernNet, But it loading the project will fail.

I tried to enable UseModernNet , It will load project success but it will not found ManagedMinimumRules.ruleset, and type something will not find request.

@Edemilorhea If your Full Framework project is not using the new SDK-style project. You can using the try-convert dotnet tool (link) to convert from the old-style project to an SDK-style project. Or you can disable omnisharp.useModernNet. This would require you to install the Visual Studio Build Tools to load your project. You can find links to download it from our requirements https://github.com/OmniSharp/omnisharp-vscode#requirements

@JoeRobich
Hello JoeRobich thanks your reply , I have tried to disable omnisharp.useModernNet, and already installed Visual Studio Build Tools, But it still dosn't load project successful.

I wanna try to use try-convert dotnet tool, But this is my project at the work, So idk if i convert it, Can anyone else successfully read it?

update:
I found OmniSharp doen't load myproject.sln, it's load path is wrong, my project sln at C:XXXX\Myproject\Myproject.sln, but it load path is C:XXXX\Myproject\Myproject\Myproject.sln it path same to Myproject.csproj folad.

IDK how to change load .sln path, so I move .sln in to next folder ( I don't know can i do this? ) ,anyway it looks like load successful, But it have other wrong still not have intellisense and highlight.

No symbol found. File: c:\VES_Web\Working\WatchsoftAms\WatchsoftAms\Controllers\XXXX.cs, Line: 77, Column: 47.

@Edemilorhea This sounds very odd. If you have omnisharp.defaultLaunchSolution set in your settings, try clearing it.

Could you share the OmniSharp Log from the Output pane now that you have gotten farther?

[Edemilorhea]

omnisharp.defaultLaunchSolution is not set anything.

This is dosen't use modern net:

We are running into this issue dotnet/msbuild#7873 (comment) and looks like Omnisharp-Roslyn needs to update the version of System.Memory they are referencing.

[Edemilorhea]

@JoeRobich Yes, I having try it now, But My Web.config and WatchsoftAms.csproj their System.Memory all the 4.0.1.2 my nuget also is 4.5.5 version.

But it still happen "System.ReadOnlySpan1<Char> Microsoft.IO.Path.GetFileName(System.ReadOnlySpan1)'。"

[JoeRobich]

@Edemilorhea Sorry, the issue is with the version of System.Memory that is referenced by the OmniSharp Language Server which powers the C# extension. Until it gets updated you will continue to see this issue when using newer builds of the VS Build Tools.

[Edemilorhea]

@JoeRobich Oh I just need keep wait extension update?

[JoeRobich]

Yes, I will look into updating OmniSharp-Roslyn this afternoon to fix this issue. Once it has updated you will be able to set your omnisharp.path to latest to pull in the rolling developer builds. I will comment back when a new build is available.

[JoeRobich]

This will have to wait until next week. Will try to tackle it first thing.
