Remarks

Confidential client applications are typically applications which run on servers (web apps, web API, or even service/daemon applications). They are considered difficult to access, and therefore capable of keeping an application secret (hold configuration time secrets as these values would be difficult for end users to extract). A web app is the most common confidential client. The clientId is exposed through the web browser, but the secret is passed only in the back channel and never directly exposed. For details see https://aka.ms/msal-net-client-applications

Fields

AttemptRegionDiscovery

Instructs MSAL to try to auto discover the Azure region.

Properties

AppConfig	Details on the configuration of the ClientApplication for debugging purposes. (Inherited from ClientApplicationBase)
AppTokenCache	Application token cache. This case holds access tokens for the application. It's maintained and updated silently if needed when calling AcquireTokenForClient(IEnumerable<String>)
Authority	Gets the URL of the authority, or security token service (STS) from which MSAL.NET will acquire security tokens The return value of this property is either the value provided by the developer in the constructor of the application, or otherwise the value of the Microsoft.Identity.Client.ApplicationBase.DefaultAuthority static member (that is `https://login.microsoftonline.com/common/`) (Inherited from ClientApplicationBase)
Certificate	The certificate used to create this ConfidentialClientApplication, if any.
UserTokenCache	User token cache. It holds access tokens, id tokens and refresh tokens for accounts. It's used and updated silently if needed when calling AcquireTokenSilent(IEnumerable<String>, IAccount) or one of the overrides of AcquireTokenSilent(IEnumerable<String>, IAccount). It is updated by each AcquireTokenXXX method, with the exception of `AcquireTokenForClient` which only uses the application cache (see `IConfidentialClientApplication`). (Inherited from ClientApplicationBase)

Methods

AcquireTokenByAuthorizationCode(IEnumerable<String>, String)	Acquires a security token from the authority configured in the app using the authorization code previously received from the STS. It uses the OAuth 2.0 authorization code flow (See https://aka.ms/msal-net-authorization-code). It's usually used in web apps (for instance ASP.NET / ASP.NET Core web apps) which sign-in users, and can request an authorization code. This method does not lookup the token cache, but stores the result in it, so it can be looked up using other methods such as AcquireTokenSilent(IEnumerable<String>, IAccount).
AcquireTokenForClient(IEnumerable<String>)	Acquires a token from the authority configured in the app, for the confidential client itself (in the name of no user) using the client credentials flow. See https://aka.ms/msal-net-client-credentials.
AcquireTokenInLongRunningProcess(IEnumerable<String>, String)	Retrieves an access token from the cache using the provided cache key that can be used to access another downstream protected web API on behalf of a user using the OAuth 2.0 On-Behalf-Of flow. See Long-running OBO in MSAL.NET. Use to stop the long running process and remove the associated tokens from the cache.
AcquireTokenOnBehalfOf(IEnumerable<String>, UserAssertion)	Acquires an access token for this application (usually a Web API) from the authority configured in the application, in order to access another downstream protected web API on behalf of a user using the OAuth 2.0 On-Behalf-Of flow. See https://aka.ms/msal-net-on-behalf-of. This confidential client application was itself called with a token which will be provided in the `userAssertion` parameter.
AcquireTokenSilent(IEnumerable<String>, IAccount)	[V3 API] Attempts to acquire an access token for the `account` from the user token cache. See https://aka.ms/msal-net-acquiretokensilent for more details (Inherited from ClientApplicationBase)
AcquireTokenSilent(IEnumerable<String>, String)	[V3 API] Attempts to acquire an access token for the IAccount having the Username match the given `loginHint`, from the user token cache. See https://aka.ms/msal-net-acquiretokensilent for more details (Inherited from ClientApplicationBase)
GetAccountAsync(String, CancellationToken)	Get the IAccount by its identifier among the accounts available in the token cache. (Inherited from ClientApplicationBase)
GetAccountAsync(String)	Get the IAccount by its identifier among the accounts available in the token cache. (Inherited from ClientApplicationBase)
GetAccountsAsync()	Returns all the available accounts in the user token cache for the application. (Inherited from ClientApplicationBase)
GetAccountsAsync(CancellationToken)	Returns all the available accounts in the user token cache for the application. (Inherited from ClientApplicationBase)
GetAccountsAsync(String, CancellationToken)	Get the IAccount collection by its identifier among the accounts available in the token cache, based on the user flow. This is for Azure AD B2C scenarios. (Inherited from ClientApplicationBase)
GetAccountsAsync(String)	Get the IAccount collection by its identifier among the accounts available in the token cache, based on the user flow. This is for Azure AD B2C scenarios. (Inherited from ClientApplicationBase)
GetAuthorizationRequestUrl(IEnumerable<String>)	Computes the URL of the authorization request letting the user sign-in and consent to the application accessing specific scopes in the user's name. The URL targets the /authorize endpoint of the authority configured in the application. This override enables you to specify a login hint and extra query parameter.
InitiateLongRunningProcessInWebApi(IEnumerable<String>, String, String)	Acquires an access token for this web API from the authority configured in the application, in order to access another downstream protected web API on behalf of a user using the OAuth 2.0 On-Behalf-Of flow. See Long-running OBO in MSAL.NET. Pass an access token (not an ID token) which was used to call this confidential client application in the `userToken` parameter. Use to stop the long running process and remove the associated tokens from the cache.
RemoveAsync(IAccount, CancellationToken)	Removes all tokens in the cache for the specified account. (Inherited from ClientApplicationBase)
RemoveAsync(IAccount)	Removes all tokens in the cache for the specified account. (Inherited from ClientApplicationBase)
StopLongRunningProcessInWebApiAsync(String, CancellationToken)	Stops an in-progress long-running on-behalf-of session by removing the tokens associated with the provided cache key. See Long-running OBO in MSAL.NET.

Explicit Interface Implementations

IByRefreshToken.AcquireTokenByRefreshToken(IEnumerable<String>, String)
IByUsernameAndPassword.AcquireTokenByUsernamePassword(IEnumerable<String>, String, String)	Acquires a token without user interaction using username and password authentication. This method does not look in the token cache, but stores the result in it. Before calling this method, use other methods such as AcquireTokenSilent(IEnumerable<String>, IAccount) to check the token cache.

Extension Methods

StopLongRunningProcessInWebApiAsync(ILongRunningWebApi, String, CancellationToken)	Stops an in-progress long-running on-behalf-of session by removing the tokens associated with the provided cache key. See Long-running OBO in MSAL.NET.
GetCertificate(IConfidentialClientApplication)	Returns the certificate used to create this ConfidentialClientApplication, if any.
