Failed to build OmniSharp.Abstractions

See original GitHub issue

@troydai Following our comments at https://github.com/dotnet/cli/issues/1618#issuecomment-191970379

I don’t have the DNX_UNSTABLE_FEED set on my Win10 laptop. It fully restores, but I ran into this (twice) attempting to build …

[EDIT] Should I attempt to strip the dnx451 framework out of the project.json files and attempt a build on dnxcore50 or netstandardapp1.5?

@troydai @hal-ler … yes … @hal-ler … thank you much … your workaround worked for me. I installed the .NET Framework from https://www.microsoft.com/en-us/download/details.aspx?id=49978

I copied the folder …

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1`

to a folder called …

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1`

The ./build.ps1 script ran to completion …

omnisharp-published-ok

My apps targeting netstandardapp1.5 (with the usual imports) are getting intellisence with the VS Code workspace setting …

"csharp.omnisharp": "C:\\omnisharp-roslyn-dev\\artifacts\\publish\\OmniSharp\\dnxcore50\\
OmniSharp.exe"

I’m good. Thanks again to both of you for your help. I plan to stop pulling down DNX runtimes now, so let me know if that’s going to be a problem.

For me the original error popped up from a lack of .NET 4.5.1 Reference Assemblies on my system. One recommended solution was to install VS. I found an alternate hack, by installing: https://www.microsoft.com/en-us/download/details.aspx?id=49978 and creating a copy for 4.5.1 of the folder “C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.6.1”.
