Mono MSBuild error after installing reference assemblies Ubuntu 18.04
1
I would like to build a .net framework 4.7.2 project in Mono on Ubuntu 18.04
I installed mono-devel according to this guide:
https://www.mono-project.com/download/stable/
After installing and trying to run msbuild on one of my projects, I get this error:
/usr/lib/mono/msbuild/15.0/bin/Microsoft.Common.CurrentVersion.targets(1195,5): error MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.7.2" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.
I found a reference assemblies package which I installed:
mono-reference-assemblies-4.0
After installing the package and running the build again, I am getting the following error:
MSBUILD : error MSB1025: An internal failure occurred while running MSBuild.

Any help would be greatly appreciated.

how did you install mono? this looks like you had a previous version of mono installed (4.6.2) before you installed the new one; you have to remove any mono related packages before installing the new version I reckon

mono-reference-assemblies-4.0 package doesn't come from the stable channel of the new apt source that you added to install your new version of Mono, so you're mixing versions of Mono at runtime, which is causing those weird exceptions.
The solution is to uninstall this package and switch to unstable channel (because .NET 4.7.2 is too new for the stable one).

mono-reference-assemblies-4.0 package doesn't come from the stable channel of the new apt source that you added to install your new version of Mono, so you're mixing versions of Mono at runtime, which is causing those weird exceptions.
The solution is to uninstall this package and switch to unstable channel (because .NET 4.7.2 is too new for the stable one).

how did you install mono? this looks like you had a previous version of mono installed (4.6.2) before you installed the new one; you have to remove any mono related packages before installing the new version I reckon

or maybe the package
mono-reference-assemblies-4.0comes from the old version; to double check this, you need to know from which apt source is that package coming from; maybeapt-cachegives you this info?– knocte

mono-reference-assemblies-4.0is coming from universe andmono-develis installed from the mono project repo I added as per the instructions I mentioned above. I can't seem to find reference assemblies elsewhere.– Tjaart

that's the problem, you're mixing 3.x with 5.x packages
