@BrutalBirdie do you have a well-formed solution file? as it appears omnisharp has not managed to find any projects in the solution and complains that:

OmniSharp.MSBuild.SolutionParsing.InvalidSolutionFileException: Solution header should be on first or second line.

could you paste the contents of /home/eha/Dokumente/Schule/AS/KW_38/TowersOfHanoi.sln ?

BrutalBirdie commented 6 years ago

It is actually a .cs file I just renamed it to .sln I just read more documentation about dotnet c# visual studio code etc.

Do I have to create a new project via dotnet new console dotnet restore ? Why does the omnisharp server only start with .sln files ? and not with .cs files?

razzmatazz commented 6 years ago

You need to have both .sln and .csproj files, in some cases you can avoid a .sln, though. A plain .cs file is not enough, and a .cs file cannot be subsitituted for a .sln or .csproj file (which is in XML) as the basic project structure for C# requires a .csproj in the root directory of the project file to define properties of the project (dependency packages/projects, constants, target framework, etc.).

Solution file is used to combine multiple projects into a solution (among other things) – you may want to check out dotnet sln command as well, https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-sln

So yes, you need to create a .csproj file (via dotnet new) and then a solution file for the project to be properly loadable in omnisharp.

Will try that and report back

My steps. I created a new project mkdir Test cd Test dotnet new console dotnet restore dotnet net sln

ls -lah

Now I open the Program.cs with Emacs Start the omnisharp server omnisharp-start-omnisharp-server I select the Test.sln file Try to TAB complete

I have to RTFM! Myself... dotnet sln add Test.sln Test.csproj Now emacs. Thanks for the hint. https://puu.sh/yhoN5/9006831f16.png

BrutalBirdie commented 6 years ago

Just for summary. (Maybe add this to the Docs?)

Create a working dir

mkdir Test

go into the dir

cd Test

Create a new project (example is a console app)

dotnet new console

dotnet restore

Create a solution file

dotnet new sln

Add the solution to your project

dotnet sln add Test.sln Test.csproj
