Gitversion task and vscode omnisharp using .NET Core SDK 2.1.500

[kieranbenton]

Originally reported here: GitTools/GitVersion#1503

Using gitversion 4.0.1-beta1.50 (I believe which uses 2.9.1?) a command line build works fine on SDK 2.1.500... BUT when using vscode and omnisharp 1.32.8 I'm getting failures - meaning that intellisense etc isn't working for me. On windows btw.

Exception is:

Any more details just let me know?

Thanks for opening issue! First question that pops into my mind: did you do command build using dotnet build or the MSBuild.exe from VS installation?

Do you have any small repro project that I can download and use to test? I also have Windows machine so I could do the testing relatively easily. :)

[kieranbenton]

No problem! So I did dotnet build from the commandline (or indeed from within a task in vscode) then I have no problems and gitversion does its thing - including several [NuGet Minimal]: Restoring packages for C:\Users\kiera\.nuget\packages\gitversiontask\4.0.1-beta1-50\build\functionality\GitVersionBuild.targets.... I gather that is normal?

I'll see if I can build you a small repro, will get back to you on that.

[kieranbenton]

Here you go - easy to minimally reproduce. Just did a plain dotnet new console app - added .gitignore and a .vscode config + initialised with git and made a single commit.

dotnet build in commandline or in vscode task works fine. But if you open the omnisharp log - you get the same error:

[stazz]

The reason why I thought this would be .NET Desktop-related is because of this error line: The task factory "UtilPack.NuGet.MSBuild.NuGetTaskRunnerFactory" could not be loaded from the assembly "C:\Users\kiera\.nuget\packages\utilpack.nuget.msbuild\2.9.1\build\\net46\UtilPack.NuGet.MSBuild.dll", specifically the net46 folder in that file path. The .NET Core version is within netcoreapp1.1 folder within the build directory.

I guess this leaves us with the following questions:

• Which assembly version OmniSharp should load?
• If OmniSharp is loading the wrong version (e.g. Desktop instead of Core), then why is it doing so, and how it can be avoided?

The detection on which assembly to load works like this currently (taken from UtilPack.NuGet.MSBuild.props file within the build directory):

    <UtilPackNuGetMSBuildToolsRootPath Condition=" '$(UtilPackNuGetMSBuildToolsRootPath)' == '' ">$(MSBuildThisFileDirectory)\</UtilPackNuGetMSBuildToolsRootPath>
    <UtilPackNuGetMSBuildToolsSubPath Condition=" '$(MSBuildRuntimeType)' == 'Core' ">netcoreapp1.1\</UtilPackNuGetMSBuildToolsSubPath>
    <UtilPackNuGetMSBuildToolsSubPath Condition=" '$(MSBuildRuntimeType)' != 'Core' ">net46\</UtilPackNuGetMSBuildToolsSubPath>

So the presence of magical MSBuildRuntimeType property dictates which version to load.

What is even more weird is that the UtilPack.NuGet.MSBuild.dll within the net46 folder does not even have reference to the failing System.Runtime assembly. The offending reference is actually within System.ValueTuple.dll assembly distributed within the net46 folder. The System.Runtime reference is one of the newer stuff, but it should be present on .NET Desktop installation.

Furthermore, when I build with command line using .NET Desktop MSBuild (like this: "c:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe" c:\path\to\test.csproj), it actually builds fine, and the various GitVersion-related tasks load and run to completion without errors. But when I try to use OmniSharp MSBuild ("C:\Users\me\.vscode\extensions\ms-vscode.csharp-1.17.1\.omnisharp\1.32.8\msbuild\15.0\Bin\MSBuild.exe" c:\path\to\test.csproj ), the build itself does not even start, but instead a System.TypeInitializationException is thrown. I guess something's funky with the omnisharp, how it is run, and how its own MSBuild version works.

I peeked into OmniSharp directory (C:\Users\me\.vscode\extensions\ms-vscode.csharp-1.17.1\.omnisharp\1.32.8\), and sure enough it does have a System.Runtime.dll, but version 4.1.2.0. I also peeked to my C:\Windows\Microsoft.NET\Framework64\v4.0.30319 directory, and there System.Runtime.dll exists as version 4.0.0.0. I tried to find some setting within OmniSharp which would allow me to change the MSBuild instance used (since it detects them on start, like it detected the VS Professional + OmniSharp embedded one for you, as seen in error logs), but I couldn't find any. Ironically, the System.ValueTuple.dll with correct version is already present in OmniSharp folder.

I will investigate if a I could fix this by loading .NET Core version of UtilPack DLL within OmniSharp, or by adding binding redirect in a .dll.config to .NET Desktop version of UtilPack DLL. I am not sure if I can make it work in both VS MSBuild and OmniSharp MSBuild.

[stazz]

Update: loading the the .NET Core version of UtilPack DLL by OmniSharp does not work, so I guess either something needs to by done in OmniSharp side (I don't know how they are using the MSBuild in such way that it is causing this different behaviour, and why did they even make their own MSBuild), or hopefully a magical .dll.config file with correct assembly redirects would work on both OmniSharp and normal VS MSBuild.

[kieranbenton]

Looks like it might be related to OmniSharp/omnisharp-roslyn#1094?

[kieranbenton]

Just to eliminate it, I have just tried the workaround in that issue - and yet still have a very similar problem (even though it seems to now be selecting the 'omnisharp' msbuild instance instead of my VS one.

Yeah I've tried the Override trick from that issue as well now, that didn't fix it either.

There is definetly something weird going on with OmniSharp. I was looking at the OmniSharp folder which contains the OmniSharp.exe, and it kinda looks like it's running on Mono... but I am not sure! I guess it runs stuff in some way different than normal VS MSBuild, or even the old XBuild from Mono. Maybe raise an issue with OmniSharp, and provide the test.zip and say that it builds normally with both dotnet and VS MSBuild, but not with OmniSharp (even when it is using VS MSBuild)? Is there any way to make OmniSharp make use actual dotnet build or C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild commands...?

I'll raise an issue and link to here - will keep you posted. Will ask for some clarity on their roadmap and how closely they're going to bind it to msbuild, but tbh I wouldn't hold your breath on that front.

I'm surprised that I'm the first person to have noticed this - of all the people using gitversion I can't be the only one using the basically stock setup of vscode w/syntax highlighting! :)

[stazz]

@kieranbenton : I haven't forgot about this issue, btw, but I've been tremendously busy with adding a CI pipeline to all of my projects (some of which have stuff like custom IL code generation and CS code generation during their build process). That task is luckily soon done tho.

Regarding your usecase - I am not sure if VSCode is that popular among C# developers. Most people use VS, either free Community edition, or paid Professional/Enterprise editions. But I am sure more people will move towards VSCode-based usage scenario, as VSCode has CodeLens (as did VS Community before 2017 version), at least for now.

[kieranbenton]

Not a problem @stazz - I absolutely apprecitate the help and insight. Just the fact that this involves binding redirects is enough to make me break out in a cold sweat :)

In terms of popularity I would say that tides are shifting. I'm a long standing old school .NET framework guy who is trying to update his skills, and certianly anyone new coming to the ecosystem of .NET Core is being pushed down the vscode route. Googling 'getting started with dotnet core" (for me at least) and the 4th entry is "https://docs.microsoft.com/en-us/dotnet/core/tutorials/with-visual-studio-code" and the ones above that are just using the command line. So I'd expect the balance to change ;-)
