I'm using VS2019 16.5 P2, but it used to happen with P1 as well. Can't confirm if it happened before. It appears that this only happens when Alt+Enter (or Ctrl + .) is pressed; this also does not happen with Disasmo disabled / uninstalled.

I have exactly same problem.

I had suspicion it's interfering with some other extension. So I disabled all other VS extensions but problem remained. With all other extensions disabled a even reinstalled Disasmo but didn't help.

Using VS 16.4.5. Project file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>
</Project>

Code:

using System;

namespace ConsoleApp2
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine();
        }
    }
}

Click on Main and press "Ctrl+.". Result is just exception described above. No actions will be available (not event default IDE suggestions).

Ouch doesn't sound good, @Gnbrkm41 @kindermannhubert when you mention Alt+Enter/Ctrl+"." do you mean Roslyn actions or maybe you have R# installed?

[Gnbrkm41]

I do not have R# installed, and yes it is the Roslyn actions.

[EgorBo]

@sharwell maybe it sounds familiar to you? I have no idea how my extension messes things up in VS2019 so the problem remains even if it's disabled/uninstalled 🙁🙁

updated all dependencies just in case, maybe will help (I can't repro the issue)

[kindermannhubert]

@EgorBo Sorry, maybe I wasn't clear enough - when I disable Disasmo VS works just fine. I was trying to disable all extensions except Disasmo to find out if it helps but it does not. I do not have R# too.

[kindermannhubert]

Last update didn't help.

Interestingly when I don't use keyboard to trigger the actions it works (just click on 'Main' and click on light bulb): but when I press Ctrl+. it will fail (even after successful opening of Disasmo window with mouse):

[Gnbrkm41]

Same here. The exception also seems to prevent opening the roslyn actions window with the shortcut unless VS is restarted.

[kindermannhubert]

Now works fine for me. Thanks.
