Steps to reproduce

Example Issue is here: https://github.com/Azure/PSRule.Rules.Azure/blob/main/src/PSRule.Rules.Azure/Data/Template/ExpressionHelpers.cs#L218

Where the refactor suggestion is 'if' statement can be simplified [PSRule.Rules.Azure].

If you try Ctrl + ., it says No code actions available.

Expected behavior

This stopped working recently. Ussually I can refactor with Ctrl + . just fine.

Actual behavior

No code actions available message popup.

The text was updated successfully, but these errors were encountered:

lonix1 · 2022-03-13T08:46:29Z

I have this too!

If you try ctrl+. a few times does it eventually work? May be related to #5085 and #5091

There are a MANY problems with the newest version. vscode devs, please release a hotfix for #5089 so we don't have to wait a whole month for the next release. Rolling back is also no good as there were bugs there too, so were excited to upgrade to this release, but now there are new bugs!

filipw · 2022-03-14T08:26:37Z

According to the exception in your logs, the analyzer your project is trying to load is relying on some type that is unavailable. This is a relatively common problem on the minimal Mono that OmniSharp by default ships with.

Probably the best solution would be to switch to the .NET 6 build of OmniSharp by setting "omnisharp.useModernNet": true" - unless you are developing a Unity project, which would require you to install latest preview global Mono and set "omnisharp.useGlobalMono":"always".

lonix1 · 2022-03-15T12:17:44Z

I am using the dotnet6 build, NOT unity, with "omnisharp.useModernNet": true, "omnisharp.useGlobalMono": "never"".

filipw · 2022-03-15T14:22:00Z

This is not the same problem , only looks similar.

In your case the missing type is 'Microsoft.CodeAnalysis, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. This means your analyzers require Roslyn 4.1.0 but your OmniSharp does not have it, which tells me you are on old version of the extension.

OmniSharp was upgraded to Roslyn 4.1.0 OmniSharp/omnisharp-roslyn#2329 here, which shipped in extension 1.24.1. You need to upgrade to that.

ArmaanMcleod · 2022-03-30T11:53:49Z

@filipw Thanks for providing this. Unfortunately we can't really upgrade .NET 6 SDK just yet. Not really a big issue, I can just do code refactoring through VS for the time being.

Would be great if upgrades were more backwards compatible with older .NET versions, since this was working for me not to long ago.

Any chance this could get fixed in an upcoming release or is upgrading the only option?

filipw · 2022-03-30T13:38:10Z

The types needed at runtime are not dictated by OmniSharp but by our dependencies (primarily Roslyn) and any analyzer packages your project would use. The minimal Mono bundled by OmniSharp does not have the full .NET type surface available for size reasons and such missing type errors happen(ed) from time to time. You did not post the full log so I do not known which OmniSharp mode you are running, but judging by the exception I am guessing it is this minimal Mono.

Now that said, this minimal Mono mode (that was used by default so far) is currently deprecated, is no longer maintained and has already been removed in the latest beta version.

Going forward you have two options:

install .NET 6 SDK on your machine, and set "omnisharp.useModernNet": true to opt into the most stable and fastest OmniSharp build. This will become the default (see Announcement: Planned removal of the included Mono & MSBuild tools #5120) in the next release.
install the latest Mono Preview, set "omnisharp.useModernNet": false and "omnisharp.useGlobalMono": "always" to run OmniSharp on global Mono

In either case, the full .NET type surface will be available.

jonkelling · 2023-04-12T14:45:52Z

I just came across this, but the latest suggestion is not working for me. I installed Mono for Windows x64. useGlobalMono is no longer available. I set the monoPath to C:\Program Files\Mono. Works fine in macOS.

jtsom · 2023-04-24T13:35:52Z

I am also seeing this on a small .NET 7 project. Simple code fixes are not available (naming violations, etc.) Seeing the same System.Reflection.ReflectionTypeLoadExceptoin over and over.

Experiencing this issue as well

thewhitewayofdelight · 2023-07-16T12:01:07Z

Months passed already.

Just as Jonkelling said, it works normally on MacOS, but not on Windows. I don't know why...
I tried to use the same C# version and mono version from Mac OS, but still can't make it work on Windows.

GrahamMThomas · 2023-12-21T20:02:51Z

Same here! How to fix this? Its pretty annoying.

DanteMarshal · 2024-07-05T08:19:34Z

I get this in Unity, trying to load a DLL that I built myself and put right there in unity, with Full Paths set in the .csproj file.
I get similar errors with useModernDotNet either on or off.
I also get a not-so-similar but close-enough error when developing Asp.Net MVC that includes one or more Razor pages, I've made another issue for that.

The amount of time I've recently spent trying to make intellisense just work with CSharp is more than I've actually coded anything. I'm really considering changing my IDE or something.

jonkelling · 2024-07-05T12:26:52Z

A while back there were a few changes, and since then everything has been working better.

Visual Studio Code Editor package in Unity has been replaced by Visual Studio Editor package. Make sure you are up to date
Make sure to Visual Studio Code is selected, or re-selected in Unity's External Tools Preferences after doing # 1. Regenerate project files.
Use the latest C# and C# Dev Kit extensions in Visual Studio Code and make sure use modern .net is checked in VS Code settings
Use the newest office Unity extension from Microsoft in VS Code.

Make sure, if you're using assembly definitions, that your .asmdef file has the DLL listed in precompiledReferences
