Could not load type 'System.IdentityModel.Tokens.TokenValidationParameters'

[ArtemAvramenko]

I upgraded nuget packages:

• Microsoft.IdentityModel.Tokens, Version=5.1.4.0
• Microsoft.Owin.Security.OpenIdConnect, Version=3.1.0.0

and got an error:

Could not load type 'System.IdentityModel.Tokens.TokenValidationParameters' from assembly 'System.IdentityModel.Tokens.Jwt, Version=5.1.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

   at Microsoft.Owin.Security.OpenIdConnect.OpenIdConnectAuthenticationOptions..ctor(String authenticationType)
   at Microsoft.Owin.Security.OpenIdConnect.OpenIdConnectAuthenticationOptions..ctor()

Is OWIN compatible with latest IdentityModel?

You've to install latest RC version

@ysmoradi Same error with 3.1.0-rc1

IdentityModel 5.x is not compatible. We're working on it.

@Tratcher Is there any possibility of delivering sooner?
I faced this problem twice in current quarter both the time, I've been using twilio 5.5.12 nuget package which has dependency on System.IdentityModel.Tokens.Jwt 5.1.2. BUT Microsoft.Owin.Security.OpenIdConnect 3.1.0 nuget isn't compatible with System.IdentityModel.Tokens.Jwt 5.1.2.

And by this, it doesn't allow to downgrade as well!

[Tratcher]

We have to wait for a final version of 5.2.0 to release. Right now we only have a preview. It will be at least another month.

[HiranPeri]

@Tratcher Thank you for replying FAST.
You meant this - System.IdentityModel.Tokens.Jwt -Version 5.2.0-preview1-408290725? I'll try with preview version and see if that solves problem.

I have recently been running into this error, updating Microsoft.IdentityModel.Tokens to 5.2.0-preview1-408290725 did not resolve my issues.

It appears you have an alpha of 4.0.0, is that worth a shot or still too early?

[Tratcher]

Please use 4.0

Sorry, just found that issue where that declaration was made.

@HiranPeri I have the same issue with Twilio. I'm going to have to create a separate Web Service that has not OAuth and leave it exposed until this get's resolved.

@SosaWiseHome, Fine! I'm using Twilio as well and I'd like to know what you're doing to solve it.
My application is using those both frameworks (IdentityServer and Twilio) and because this MIcrosoft issue, I'm not getting to progress in my project

[HiranPeri]

@SosaWiseHome & @2pip2 I solved this by downgrading Twilio to 4.X version (Rest API based instead of SDK) and then 'System.IdentityModel.Tokens.Jwt' to '4.0.X'.

[2pip2]

Hi @HiranPeri, Thank very much! I appreciate a lot.
But, when I tryied downgrading 'System.IdentityModel.Tokens.Jwt' to version '4.0.X' show me the following:
One or more unresolved package dependency constraints detected in the existing packages.config file. All dependency constraints must be resolved to add or update packages. If these packages are being updated this message may be ignored, if not the following error(s) may be blocking the current package operation: 'System.IdentityModel.Tokens.Jwt 5.1.4'
