I have an ASP.NET Website project. It's package.config
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Microsoft.Bcl.AsyncInterfaces" version="8.0.0" targetFramework="net48" />
<package id="Microsoft.CodeAnalysis.NetAnalyzers" version="8.0.0" targetFramework="net48" developmentDependency="true" />
<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.WebSites" version="4.1.0" targetFramework="net48" />
<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="4.1.0" targetFramework="net48" />
</packages>
Then Web.config looks like, just pasting the runtime binding section related to CodeAnalysis,
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.CodeAnalysis" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.7.0.0" newVersion="4.7.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Collections.Immutable" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Microsoft.CodeAnalysis.CSharp" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.7.0.0" newVersion="4.7.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
Then I have a shared library project which uses RazorEngineCore library.
This is how the decompiled RazorEngine class looks,

I am getting this exception in my shared library project when I run the website. Got the following exception.

What should be done in order to resolve this Microsoft.CodeAnalysis related exception?
UPDATE: I am getting this error at runtime, project builds fine.
Your binding redirects are wrong. As you can see in your Web.config you have:
<dependentAssembly>
<assemblyIdentity name="Microsoft.CodeAnalysis" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.7.0.0" newVersion="4.7.0.0" />
</dependentAssembly>
Redirect to version 4.7.0.0 but your RazorEngineCore resolves Microsoft.CodeAnalysis the 4.8.0.0 version.
Generating new binding redirects should fix your issue
