ServiceLocator & NETStandard.Library (2.0.0) - SimpleIoc.Default not valid

Question

User355271 posted

I am working on a new App with .Net Core, and when I try to implement my "Bootstrap application" (a basic app with some core functions) I get stuck when trying to set the ServiceLocator ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);

I get the following errors: * Cannot implicitly convert type 'GalaSoft.MvvmLight.Ioc.SimpleIoc' to 'CommonServiceLocator.IServiceLocator'. An explicit conversion exists (are you missing a cast?) (CS0266) (Mobile) * The type 'IServiceLocator' is defined in an assembly that is not referenced. You must add a reference to assembly 'Microsoft.Practices.ServiceLocation, Version=1.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. (CS0012) (Mobile)

I tried adding the assembly 'Microsoft.Practices.ServiceLocation' but it has no compatibility NETStandard.Library (2.0.0)

Any idea how to solve this ? Thanks in advance !

After some more research I found an article from the author of MvvmLight explaining how to use MvvmLight with NETStandard 1.0. (I don't have the rights to post links yet) I had ignored it at first since I am trying to use 2.0 The article explains where the error I was facing came from.

In MVVM Light for .NET Standard 1.0, I decided to remove this dependency completely. As a result, it means that the ServiceLocator class is not available anymore. In the rest of the code, you need to remove every mention to ServiceLocator.Current and replace with SimpleIoc.Default

Anyway, after some fiddling with dependencies and obsolete code, everything works as expected

Hi Theo ! I faced with the same issue, but I cannot understand what to do with this error. Have you removed this line ? : ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default); What NuGet have you used ? For me - CommonServiceLocator 2.1.0 - MvvmLightLibsStd10 5.4.0.1-alpha

Ok I found the link I needed. Just remove the line with ServiceLocator and use directly the SimpleIoC class :smile:
