msbuild -tl option not supported on ubuntu, msbuild 17.0.1+b177f8fa7, dotnet 6.0.123

[stone-w4tch3r]

Trying to build on ubuntu 23.04, kernel 6.2.0-34-generic (64-bit)

$ dotnet --list-sdks 
6.0.123 [/usr/lib/dotnet/sdk]
7.0.112 [/usr/lib/dotnet/sdk]

$dotnet msbuild -v 
Microsoft (R) Build Engine version 17.0.1+b177f8fa7 for .NET

$cat global.json 
{
    "sdk": {
        "version": "6.0.123",
        "rollForward": "latestMinor"
    }
}

Got error: MSBUILD : error MSB1001: Unknown switch. Switch: -tl when trying to build

Error is caused by .Append("/tl") in build.cake, line 246

When commenting out this line, build proceeds fine

P.S. why I even need to build this from scratch? And why there is no packaged omnisharp in apt/brew or other package manager?

The /tl switch was added in a more recent SDK than 6.0.123. Which is why we pin our SDK to 8rc1.

We have prebuilt binaries available attached to our releases.

Yep, but installing from binaries is not very convenient too(

Anyway, thank you for answers!
