Omnisharp-vscode: OmniSharp can't find sdks, never

[ghost]

Issue Description

OmniSharp can't fiind sdks, sometimes change some setting flower issues can fix it, but next version of omnisharp or C# extension or dotnet-sdk all will be break, how omnisharp can work like that worse. And now I have to say that Java extension works more and more better than C# extension.

Hi @wenqiangxie,
Sorry you are running into issues. It appears that maybe you installed the .NET Core SDK using Scoop. We recommend using the official installer for you platform to install the .NET Core SDK.
You can find the installer here.

In case anyone is browsing this issue at a later point and using Linux, building msbuild myself helped resolve the issue.

Could you provide more info on what was the solution ?
I'm facing the same problem on Ubuntu (installing .net core with apt or asdf) and Omnisharp can't find the sdk.

Hi @flaprano,

If you have followed the instructions on installing .NET Core SDK and still having issues, could you open a new issue and include your logs?

Hi @flaprano,

Of course.
The problem is basically the same described here and on a lot of other issues but I will open a new one. :)

Do you solve this problem ?

Not exactly.
I found out that it doesn't work well with asdf and installed sdk just by apt.
In the end it worked.

[joaomarcos96]

@flaprano I got it working with asdf. I just added the following line to my .zshrc:

export MSBuildSDKsPath="$ASDF_DIR/installs/dotnet-core/3.1.202/sdk/3.1.202/Sdks"

Thanks.
I will test again.
I remember testing it that way and it didn't work. Perhaps in some update it has been corrected.

[joaomarcos96]

@flaprano Please let me know if it worked when you try.

[lzocateli00]

@joaomarcos96 I faced the same problem, that is, using Asdf on Linux Ubuntu 20.04, OmniSharp caused the error when opening the program, and did not allow, for example, navigation with F12 between classes. includes the environment variable as you indicated, and it worked, thanks.

[flaprano]

@flaprano Please let me know if it worked when you try.

Hi @joaomarcos96 , sorry on the delay on giving you a feedback.
I changed between projects on my company and now I'm more focused on ruby than c#.
I tried setting the env and in my case it didn't worked.
As your answer has helped others I think the problem may be on my installation or another library that I'm loading on my system.

A few images that shows my problem.

[mabo3n]

I also wasn't able to make it work on my Linux machine while managing versions with asdf. Tried most workarounds I found:

• Setting the MSBuildSDKsPath on my .bashrc, as suggested here
• Flagfing UseLegacySdkResolver on .omnisharp.json file as decribed here (tried within each project dir, within the solution dir, and the home dir as the docs points out)
• Symlink asdf's dotnet-core directory to possible original locations (/usr/share/dotnet/ and /usr/local/bin/dotnet pointing to $ASDF_DIR/installs/dotnet-core/), after seeing this comment.

Maybe that's a compatibility issue with the SDK or OS versions?

Anyway, it's not the first time I face problems managing dotnet versions with asdf. I would just follow my rule of thumb of using the mainstream install for dotnet core, and using asdf to anything else.
