System.Text.Json.JsonSerializer.Serialize - could not load file or assembly System.Text.Encodings.Web, Version=5.0.0.0

[livicitu]

I am using IdentityModel.OidcClient 4.0.0 to connect to KeyCloack for OIDC authentication into an application compiled with Visual Studio 2019 and target .NET Framework 4.8. I have added all dependencies for this Nuget package but at runtime I got the following exceptions when trying to connect:

{"Could not load file or assembly 'System.Text.Encodings.Web, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies.

Seems that at runtime, version 5.0.0 is searched for System.Text.Encodings.Web while at compile time version 5.0.1 is needed. Same for System.Text.Json.

Is there something I am missing? Does OidcClient 4.0.0 work with .NET Framework 4.8?

It should, it is targeting netstandard. I haven't tested it though. I am not using .NET Framework anymore...

The compilation is OK but I have runtime issues as above.

Below the list of packages I have used and their versions:

<packages>
  <package id="IdentityModel" version="5.1.0" targetFramework="net48" />
  <package id="IdentityModel.OidcClient" version="4.0.0" targetFramework="net48" />
  <package id="Microsoft.Bcl.AsyncInterfaces" version="5.0.0" targetFramework="net48" />
  <package id="Microsoft.Extensions.DependencyInjection" version="5.0.0" targetFramework="net48" />
  <package id="Microsoft.Extensions.DependencyInjection.Abstractions" version="5.0.0" targetFramework="net48" />

  <package id="System.IdentityModel.Tokens.Jwt" version="6.11.0" targetFramework="net48" />
  <package id="System.Memory" version="4.5.4" targetFramework="net48" />
  <package id="System.Numerics.Vectors" version="4.5.0" targetFramework="net48" />
  <package id="System.Reactive" version="5.0.0" targetFramework="net48" />
  <package id="System.Reactive.Linq" version="5.0.0" targetFramework="net48" />
  <package id="System.Runtime.CompilerServices.Unsafe" version="5.0.0" targetFramework="net48" />
  <package id="System.Text.Encodings.Web" version="5.0.1" targetFramework="net48" />
  <package id="System.Text.Json" version="5.0.1" targetFramework="net48" />
  <package id="System.Threading.Tasks.Extensions" version="4.5.4" targetFramework="net48" />
  <package id="System.ValueTuple" version="4.5.0" targetFramework="net48" />
</packages>

I tested also version 3.1.2 and works perfectly fine. But that version is using Newtonsoft.Json not System.Text.Json as version 4.0.0 does.

Hi everybody,

Can you please let me know if this worked for you? Is there anything we can do to bypass this issue?

Thank you

This has been fixed after upgrading IdentityModel.OidcClient to latest version and adding the folowing bindingRedirect for System.Text.Json

		<dependentAssembly>
			<assemblyIdentity name="System.Text.Json" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
			<bindingRedirect oldVersion="0.0.0.0-6.0.0.6" newVersion="6.0.0.0" />
		</dependentAssembly>

Note that the compiler complained about not using newVersion "6.0.0.6" but with that it does not work.
