I have updated my existing Web Api project to use the latest System.IdenityModel.Tokens.Jwt package and I am getting the following error:
Could not load type 'System.IdentityModel.Tokens.TokenValidationParameters' from assembly 'System.IdentityModel.Tokens.Jwt, Version=5.0.0.127, Culture=neutral,
PublicKeyToken=31bf3856ad364e35'.
Everything works fine with 4.0 version of the same package. How can I resolve this?
The answer by baldy below is correct, but you may also need to enable 32-bit applications in your AppPool.
Whilst setting up an application to run on my local machine (running Vista 64bit) I encountered this error:
Could not load file or assembly
ChilkatDotNet2or one of its dependencies. An attempt was made to load a program with an incorrect format.
Obviously, the application uses ChilKat components, but it would seem that the version we are using, is only the 32bit version.
To resolve this error, I set my app pool in IIS to allow 32bit applications. Open up IIS Manager, right click on the app pool, and select Advanced Settings (See below)
Then set "Enable 32-bit Applications" to True.
All done!
The .NET Assembly loader:
This assembly does not match what was requested and therefore you get this error.
In simple words, it can't find the assembly that was referenced. Make sure it can find the right assembly by putting it in the GAC or in the application path.

If you want to use the new version(v5) of System.IdentityModel.Tokens.Jwt and don't want to restrict your project to the v4 version, I have created a Nuget and Github project called EasyJwtAuth that uses v5(Very simple to use):
Nuget package: https://www.nuget.org/packages/EasyJwtAuth
Instructions on how to use: https://github.com/Xela101/EasyJwtAuth
Feel free to update the repository with more features, or just learn/copy the code and make your own authentication wrapper.
