How to build on Linux?

I thought I knew how to build dotnet stuff on Linux, but obviously not.

I’ve got Ubuntu 18.04 running in WSL.

I’ve got dotnet installed.

When I do:

dotnet restore
dotnet build

I get:

I didn’t think you could actually install .NET 4.7.2 on linux. If you can, I don’t know how. Hence me asking here.

Ah ok, I wasn’t pointing fingers here only providing some context because I got interested. IMO I would also just use the last one, the others I included just as an FYI.

Anyways I just tried this out on my mac, don’t have a linux setup with mono and dotnet core atm (will wack up a docker container and test later today) and it works for me.

Adding those references only allows you to build a dll or exe targetting full framework on unix. You still need a full framework runtime like mono or .NET Framework to run the generated binary. The Example and Designer projects are full framework so you can’t use dotnet core to run those because doing so will give you the error you posted above.

Example:

mono Designer/bin/Debug/Designer.exe

You should be able to fix this by adding a reference to Microsoft.NETFramework.ReferenceAssemblies from nuget.

I ran into this exact same issue a while ago and there are a few ways to work around it one of which is just using the mono build tooling. But adding the full framework reference assemblies is the easiest one, I documented the others here: https://nvd.codes/post/dotnet-build-target-net4x-on-unix-systems.

Haven’t tested this with gui.cs yet though, will see if I have some time this evening to give it a try.
