To resolve this issue. First of all, you'll need to build solution once again and then copy the .dll file "Microsoft.IdentityModel.dll" from the 'bin' folder and paste into following folders.

Please see below path here:

C:\Program Files (x86)\Common Files\microsoft shared\DevServer\11.0

After copy dll file, You'll need to restart the system or rebuild your solution. Note: Please restart application pool and site.

Now, we'll need latest licence key. Which compatible with 9.2.x.

I was facing the same issue. Resolved it by following steps:

Specify the IIS Web server for a Web application project

1. In Solution Explorer, right-click the name of the Web application project for which you want to specify a Web server, and then click Properties.
2. In the Properties window, click the Web tab.
3. Under Servers, click Use Local IIS Web server.
