The Project > Active Runtime setting dates back almost ten years in the context of desktop C# applications in MonoDevelop, before Xamarin projects were a top workload. So it is probably worth updating how that feature interacts with Xamarin projects in the modern context of Visual Studio for Mac where Xamarin projects are a key workload. Steps to reproduce • In addition to the current version of Mono Framework MDK installed by latest Visual Studio for Mac, also manually install an old version of the Mono Framework MDK from the download archive (). Pick a version that is a few releases older than the current version installed by Visual Studio for Mac. After this step, 2 different versions should be listed in /Library/Frameworks/Mono.framework/Versions/. • Open a solution. The most important scenario for this report is to open a solution that contains Xamarin projects. (Unlike Mono Framework MDK console projects, Xamarin projects have both build-time and run-time dependencies that are packaged and installed separately from the selected Active Runtime. So using a non-default Active Runtime when working with Xamarin projects is generally untested and not recommended.) • From the Project > Active Runtime menu, select the older version of the Mono Framework MDK as installed in step 1. • Build and run one of the Xamarin projects in the solution. Or close and reopen the solution and then build and run one of the Xamarin projects. Actual Results Neither the graphical user interface nor the build output warns the user that this configuration is untested and not recommended. In some scenarios this mismatched configuration will produce build error messages, but those errors will vary widely depending on which older version of the Mono Framework MDK is selected and how the dependencies have changed since then. So determining the cause of the errors will potentially be quite challenging if the user changed the Active Runtime setting long ago, used it by luck without error through several Xamarin SDK version updates, and then finally started to see errors later after another update. Possible Improvements (a) Ignore the Active Runtime setting entirely in the context of Xamarin projects, and always use the version of Mono Framework MDK that was used to launch Visual Studio for Mac. This has a potential downside that it removes some flexibility for users who might occasionally work with a newer version of Visual Studio for Mac and older Xamarin SDKs. On the other hand, those users would still be able to perform command line builds using older versions of the Mono Framework SDK, and often the latest Mono Framework MDK version will be backwards compatible with quite a few older versions of the Xamarin SDKs. Or (b) Provide one or more warning messages. For example, maybe show a warning dialog before starting a build for Xamarin projects if the Active Runtime does not match the Mono Framework MDK version that was used to launch Visual Studio for Mac. Maybe also show warning icons in the Solution Pad on any Xamarin projects if the Active Runtime is set to a mismatched version. Or maybe instead always show a warning message in the Errors Pad if the solution contains any Xamarin projects and the Active Runtime is set to a mismatched version. Cross-references to examples where the lack of a warning has caused trouble • • •. I'm trying to connect my Windows 10 to my Mac to build a Xamarin.Forms app as I've done in the past. However, I'm getting the following error: Xamarin.iOS versions mismatch The Xamarin.iOS SDK version installed on Mac is not compatible with this version of Visual Studio. Would you like us to install Xamarin.iOS '11.14' for you? This will overwrite any existing Xamarin.iOS installation on your Mac. Best flavor cheese for homemade mac and cheese. Indeed, the version on the Mac is 11.12.0.4. I'm on the stable channel, and it's telling me there are no updates. And I'm on the latest VS on my PC - 15.8.1. I tried clicking 'Install' but it fails telling me that There were problems installing. Is there a way to solve this without uninstalling and reinstalling Visual Studio (which might not even help)?
