OmniSharp.MSBuild.MSBuildProjectSystem, Failed to load project file #1135

Open doomchild opened 6 years ago

doomchild commented 6 years ago

I made a brand new solution and project like so:

$ mkdir temp
$ cd temp
$ dotnet new sln
$ dotnet new console
$ dotnet sln add temp.csproj

Then I opened up ~/temp/Program.cs, started the omnisharp server, and looked at the *omnisharp-log* buffer. Here it is:

Why didn't Omnisharp load my brand-new project file?

rchande commented 6 years ago

@doomchild Per your log, you're using omnisharp 1.26. Please try updating to the latest release (1.29.1) to see if that helps.

doomchild commented 6 years ago

I've tried with both 1.26 and 1.29, and had the same results.

doomchild commented 6 years ago

Gah, didn't mean to close it. Hit the wrong button.

rchande commented 6 years ago

@doomchild Can you try running omnisharp with the argument --loglevel debug and post your log? Note that it might also be interesting for you to try the steps I posted here: https://github.com/OmniSharp/omnisharp-vscode/issues/2147#issuecomment-380171885 (requires VS Code)

j0057 commented 6 years ago

I can reproduce this with the same steps @doomchild posted:

nickspoons commented 6 years ago

@j0057 I don't know if this is a fix, but to at least exclude the possibility, could you try using the absolute path to OmniSharp, instead of the ~ path?

j0057 commented 6 years ago

That gives the same result – bash expands the tilde to an absolute path.

ghost commented 6 years ago

I can also confirm this happens to me... Used the same steps as @doomchild

Edit:

I can also confirm that installing msbuild-stable 15.6_xamarinxplat.2018.01.17.14.14_0xamarin1_ubuntu1404b1-3 fixes this issue... Really strange.

DustinCampbell commented 6 years ago

I suspect the problem is here:

$ mono ~/git/dotfiles/omnisharp-http-mono/OmniSharp.exe -l Debug

Try specifying --assembly-loader=strict to your mono arguments like the OmniSharp run script does.

ghost commented 6 years ago

I will apologize upfront, as the debug output is quite long.

Testing your suggestion by providing the --assembly-loader=strict argument as well as the debug flag, we can see that without having msbuild-stable 15.6_xamarinxplat.2018.01.17.14.14_0xamarin1_ubuntu1404b1-3 installed, omnisharp seems to fail loading the project file.
