+
+Identity authentication application service contracts module, providing interface definitions for identity authentication-related application services.
+
+## Features
+
+* Extends Volo.Abp.Identity.AbpIdentityApplicationContractsModule module
+* Provides interface definitions for identity authentication-related application services
+* Provides DTO object definitions for identity authentication
+* Integrates ABP authorization module
+
+## Module Dependencies
+
+```csharp
+[DependsOn(
+    typeof(AbpIdentityApplicationContractsModule),
+    typeof(AbpIdentityDomainSharedModule),
+    typeof(AbpAuthorizationModule))]
+public class YouProjectModule : AbpModule
+{
+  // other
+}
+```
+
+## Service Interfaces
+
+* IIdentityUserAppService - User management service interface
+* IIdentityRoleAppService - Role management service interface
+* IIdentityClaimTypeAppService - Claim type management service interface
+* IIdentitySecurityLogAppService - Security log service interface
+* IIdentitySettingsAppService - Identity settings service interface
+* IProfileAppService - User profile service interface
+
+## DTO Objects
+
+* IdentityUserDto - User DTO
+* IdentityRoleDto - Role DTO

+* GetIdentityRolesInput - Get role list input DTO
+* IdentityUserCreateDto - Create user DTO
+* IdentityUserUpdateDto - Update user DTO
+* IdentityRoleCreateDto - Create role DTO
+* IdentityRoleUpdateDto - Update role DTO
+
+## Basic Usage
+
+1. Implement user management service interface
+```csharp
+public class YourIdentityUserAppService : IIdentityUserAppService
+{
+    public async Task<IdentityUserDto> GetAsync(Guid id)
+    {
+        // Implement logic to get user
+    }
+
+    public async Task<PagedResultDto<IdentityUserDto>> GetListAsync(GetIdentityUsersInput input)
+    {
+        // Implement logic to get user list
+    }
+}
+```
+
+2. Implement role management service interface
+```csharp
+public class YourIdentityRoleAppService : IIdentityRoleAppService
+{
+    public async Task<IdentityRoleDto> GetAsync(Guid id)
+    {
+        // Implement logic to get role
+    }
+
+    public async Task<PagedResultDto<IdentityRoleDto>> GetListAsync(GetIdentityRolesInput input)
+    {
+        // Implement logic to get role list
+    }
+}
+```

+    }
+}
+```
+
+2. 实现角色管理服务接口
+```csharp
+public class YourIdentityRoleAppService : IIdentityRoleAppService
+{
+    public async Task<IdentityRoleDto> GetAsync(Guid id)
+    {
+        // 实现获取角色的逻辑
+    }
+
+    public async Task<PagedResultDto<IdentityRoleDto>> GetListAsync(GetIdentityRolesInput input)
+    {
+        // 实现获取角色列表的逻辑
+    }
+}
+```

+Identity authentication application service module, providing implementation of identity authentication-related application services.
+
+## Features
+
+* Extends Volo.Abp.Identity.AbpIdentityApplicationModule module
+* Provides implementation of identity authentication-related application services
+* Integrates AutoMapper object mapping
+* Supports user avatar URL extension property
+
+## Module Dependencies
+
+```csharp
+[DependsOn(
+    typeof(AbpIdentityApplicationModule),
+    typeof(AbpIdentityApplicationContractsModule),
+    typeof(AbpIdentityDomainModule))]
+public class YouProjectModule : AbpModule

+    }
+}
+```
+
+2. Using role management service
+```csharp
+public class YourService
+{
+    private readonly IIdentityRoleAppService _roleAppService;
+
+    public YourService(IIdentityRoleAppService roleAppService)
+    {
+        _roleAppService = roleAppService;
+    }
+
+    public async Task<IdentityRoleDto> GetRoleAsync(Guid id)
+    {
+        return await _roleAppService.GetAsync(id);
