I'm using pre-release version: v2.0.206 on Ubuntu 22.04, VSCode installed from official apt repository. which dotnet and dotnet --list-sdks work from code terminal.

Steps to reproduce

I don't know, new version just does not work no matter what.

@kemsky The xxx.Web.csproj project that is giving you an error, what type of web project is that?

[kemsky]

@jasonmalinowski, web project has Microsoft.NET.Sdk.Web, actually I cut output, there are other projects in solution but none of them loads, error message is exactly the same, all other projects are Microsoft.NET.Sdk. Is there any way to enable more detailed error reporting?

[kemsky]

@jasonmalinowski, ok, I understood what happens. I have Directory.Build.props where I set <TargetFrameworks>net7.0;</TargetFrameworks>, project files do not have such item. If I add <TargetFramework>net7.0</TargetFramework> directly to each project - it works.

[jasonmalinowski]

@kemsky And did you have the DevKit extension installed, or are using just the C# extension by itself?

[kemsky]

@jasonmalinowski, I tried with and without DevKit, the problem is caused by redundant ; in <TargetFrameworks>net7.0;</TargetFrameworks>

[jasonmalinowski]

There's another bug which means we're taking this code path that's reporting the error even if DevKit is installed, so I guess that question of mine might have not been the best. Other than the error, with either DevKit installed or not, do you still see other features like colorization or Intellisense working?

[kemsky]

@jasonmalinowski, colorization and Intellisense are working in both cases.

There is a different bug (go to definition does not work correctly when type is imported from other project, it navigates to decompiled code instead of source code), it is present only when DevKit is installed.

[jasonmalinowski]

Yep, that other one is known and is tracked as https://github.com/microsoft/vscode-dotnettools/issues/40. Based on your descriptions I think the error is going to be harmless in your case. Was the extra semicolon intentional or just some leftover from a prior change?

[kemsky]

@jasonmalinowski, there is initial delay before intellisense starts working plus unrelated bug https://github.com/microsoft/vscode-dotnettools/issues/40 so I decided that this error was critical as it usually happens with project load errors.

Was the extra semicolon intentional or just some leftover from a prior change?

Previously we had net6.0 target, so there was a list. Visual studio, rider and ci/cd can build and load this solution without any issues.

[jasonmalinowski]

Yep, I just wanted to verify you weren't expecting some other behavior here before we add a "skip blank TFMs" check in our code to silence this.

[jasonmalinowski]

@kemsky And just as an FYI, we shipped verison 2.0.212 of the C# extension earlier today which won't fix the error you're reporting in this bug, but will fix the go to definition issues you were seeing too. So I'd recommend you upgrade if you haven't already.

[Zaitonn]

the same problem appears when net6.0 and net6.0-windows are added into TargetFrameworks at the same time

Error csproj

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFrameworks>net6.0-windows;net6.0;</TargetFrameworks>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup Condition="'$(TargetFramework)'=='net6.0-windows'">
        <PackageReference Include="System.Diagnostics.PerformanceCounter" Version="8.0.0" />
    </ItemGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.Extensions.Hosting" Version="8.0.0" />

        <PackageReference Include="SystemInfoLibrary-devel" Version="1.5.0.25" />
    </ItemGroup>

</Project>

output:

but if i remove <TargetFrameworks>net6.0-windows;net6.0;</TargetFrameworks> and add <TargetFramework>net6.0</TargetFramework> , the error disappears
