Cache options in MSAL.NET

Setting cache options

var app = ConfidentialClientApplicationBuilder.Create(ClientId)
               .WithCertificate(cert)                                                               
               .Build();

// The App token cache is used by `AcquireTokenForClient`, which gets tokens on behalf of service principals
app.AppTokenCache.SetCacheOptions(CacheOptions.EnableSharedCacheOptions);

// The User token cache is used by all other AcquireToken* methods, which get tokens on behalf of users
app.UserTokenCache.SetCacheOptions(CacheOptions.EnableSharedCacheOptions);

Cache options

EnableSharedCacheOptions - makes the cache static, so that it is shared between all instances of ConfidentialClientApplication.
