Thanks I will investigate what the issue is :)

[danwalmsley]

I think I know what the problem is, I will try to push a fix soon.

[danwalmsley]

@kekekeks in this case, where someone loads. Net462 project on Linux what would you expect to happen?

Load mono version of msbuild, and parse normally?

[danwalmsley]

@andreevlex a workaround for now should be to remove your <targetframework>net462</targetframework>

Tag from csproj and replace with <targetframeworks>netcoreapp2.0;net462</targetframeworks>

Use netstandard2.0 if it's a class library, this will allow you to open it in Avalon Studio, we will work to support Net462 on Linux shortly.

[danwalmsley]

Todo

• [x] don't crash when project evaluation fails!

• [ ] support full netframework evaluation on Linux and Windows.

• [ ] support full. Net debugging on Linux

Support full. Net debugging on windows

[ava57r]

fixed? can try?

[danwalmsley]

It should open now, it wont support full. Net projects yet, only netstandard and netcore
