I m getting this error when on IDS bearer Token auth UseIdentityServerBearerTokenAuthentication . app framework 4.6 Identity Model - 3.8 here is the package info attached : - packageInfo.txt

Please help

You have <package id="Microsoft.Owin.Security.OpenIdConnect" version="4.1.0" targetFramework="net461" /> And <package id="Microsoft.Owin.Security.Jwt" version="3.0.1" targetFramework="net461" />

There were significant breaks in the IdentityModel dependencies between 3.x and 4.x. All Microsoft.Owin packages need to be 4.1.0.

Thank you for the response @Tratcher I want to specify few thing about my application here : - 1) It is a web application and we have openIdConnect and cookieAuth functional for this app with IdentityModel 3.8 2) its n -layered , and my web app is calling multi apis integrated with in the same solution.

Now we want to implement ids Bearer Token Auth for that I added IdentityServer3.AccessTokenValidation version="2.11.0" so, after i updated the packages for Owin to 4.1.0 as suggested , i can see the updated versions in the web config as well but now too I get this error :
'Could not load type 'Microsoft.Owin.Security.Jwt.IIssuerSecurityTokenProvider' from assembly 'Microsoft.Owin.Security.Jwt, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.'

and here is the package info attached: - packageInfo (1).txt

Please advise.

Your dependencies are still out of sync, something in your graph depends on Microsoft.Owin.Security.Jwt 3.x and needs to be updated. If it can't be then you'll need to downgrade Microsoft.Owin.* to 3.1.

ok , let me try that , will let u know

@Tratcher i verified dependencies of all the packages that i m using for this app, most of them are having owin dependency >=2x or >= 3x . it seems they should be compatible , but the point is i upgraded Owin to 4.1 so i can't downgrade it now,

do we have any way to catch this dependent package causing this error?

i had gone through the similar issue described here https://github.com/IdentityServer/IdentityServer3.AccessTokenValidation/issues/165 . do we have any on going issue with latest version? Please help

[Tratcher]

Indeed, it looks like IdentityServer3.AccessTokenValidation is stuck with an old dependency on Microsoft.Owin.Security.Jwt 3.0.1. There were breaking changes in 4.0 so if you want to continue using IdentityServer3.AccessTokenValidation you'll need to continue using Microsoft.Owin.Security.Jwt 3.x (and 3.x for all Microsoft.Owin packages).

thank you , yes you are correct !!, I too just found the same errors relating to IdentityServer3.AccessTokenValidation. This is the error i was able to track. Exception thrown: 'System.TypeLoadException' in IdentityServer3.AccessTokenValidation.dll An exception of type 'System.TypeLoadException' occurred in IdentityServer3.AccessTokenValidation.dll but was not handled in user code Could not load type 'Microsoft.Owin.Security.Jwt.IIssuerSecurityTokenProvider' from assembly 'Microsoft.Owin.Security.Jwt, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
