I am using Prism.DryIoc.Extensions(v8.0.62) and Prism.DryIoc.Forms(v8.1.97) which internally is using DryIoc.dll v4.7.3 and v4.7.7 respectively for my Xamarin.Forms project.

I also have a nuget update for my project which is internally using DryIoc.dll v5.0.2.

Now, If I update project nuget to the latest, It throws error. As there is a version conflict.

Since it is a project related nuget, I will have to update somehow. But there is a dependency on Prism and Prism has not released any latest version with latest DryIoc.dll.

I tried to add the following in our .csproj file

<PackageReference Include="Prism.DryIoc.Extensions" Version="8.0.62">
        <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
        <dependentAssembly>
          <assemblyIdentity name="DryIoc.dll" culture="neutral" />
          <bindingRedirect oldVersion="4.7.3" newVersion="5.0.2" />
        </dependentAssembly>
    </PackageReference>

This solved compile time error but started throwing run time error as below,

System.MissingMethodException Message=Method not found: DryIoc.Rules DryIoc.Rules.WithoutFastExpressionCompiler()

I also tried creating app.config and use the below code snippet,

<configuration>
<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="DryIoc" publicKeyToken="dfbf2bd50fcf7768" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-5.0.1.0" newVersion="5.0.2.0" />
        </dependentAssembly>
    </assemblyBinding>
</runtime>

But this is also failing with the same error as above.

Getting rid of Prism is one of the solutions but It is a huge effort as the entire project is using Prism.

What is the best possible solution to fix this? Please help me in this regard.

Prism's open source, you can modify parts to use DryIoc 5 and use those dlls.

It's not like you're forced to use nuget packages, they're meant to help. If they hinder, get rid of them.

    Prism.DryIoc.Forms is using DryIoc.dll in DryIocContainerExtension. I cloned their repo, updated DryIoc.dll to 5.0.2 and built it, Found that WithoutFastExpressionCompiler has been removed in DryIoc.dll latest. So removed the method and created a dll and started using in my project. It started working. Thanks for your answer. – Anoop H.N May 17 '22 at 06:48
