Cannot find project references after update to Big Sur
See original GitHub issueIssue Description
I want to mention that I haven’t had an issue with this Solution until after I upgraded the OS.
OK, so I have a solution which contains 7 projects. Of the 7 projects 5 are targeting net5.0.
One project targets netstandard2.0, and another targets .Net 4.8 (legacy).
The issue After upgrading my Mac to Big Sur I started receiving the following OmniSharp error in VSCode:
Can’t find custom attr constructor image: /Some/Path/net5.0/WebCommon.dll mtoken: 0x0a000001 due to: Cannot resolve dependency to assembly because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.
Now, I can build and run the projects with no issue but every project that references/uses the WebCommon project has a ton of red squiggles.
The WebCommon project is a common project (obviously) shared amongst a few of the other projects in the solution.
The WebCommon project targets net5.0 and is only included by a few of the other projects that also target net5.0 (The WebCommon project is not included by either the netstandard or .Net 4.8 legacy projects.
The WebCommon project has the following references:
<PackageReference Include="Google.Protobuf" Version="3.13.0" /><PackageReference Include="Grpc.Core" Version="2.33.1" /><PackageReference Include="Grpc.Tools" Version="2.33.1"><PackageReference Include="Microsoft.Extensions.Configuration" Version="5.0.0" /><PackageReference Include="Microsoft.Extensions.Configuration.Binder" Version="5.0.0" /><PackageReference Include="Microsoft.Extensions.Logging" Version="5.0.0" /><PackageReference Include="Nito.AsyncEx" Version="5.1.0" />
I have also ensured that omnisharp.useGlobalMono is set to never. (This was a warning emitted by OmniSharp).
Steps to Reproduce
Upgrade Mac to Big Sur and then open a C# project.
Expected Behavior
OmniSharp to detect project references.
Actual Behavior
OmniSharp cannot detect project references.

@JoeRobich sorry it’s my bad. Since I am using vs code for almost 3 years, I even forgot about Visual Studio 😃
I am updating VS now. It’s gonna work probably. Thanks.
@suadev If you have Visual Studio (or MSBuild Tools) installed be sure that you are on version 16.8 or higher. NET 5 requires a 16.8 MSBuild (see https://github.com/OmniSharp/omnisharp-vscode#note-about-using-net-5-sdks).
