Question

HI I am getting error while writing Update-Database Command through Package Manager Console in .Net Core Application. I wrote Update-Database and PMC took Update-Datebase.

PM> update-Database

System.ArgumentException: Keyword not supported: 'datebase'. at Microsoft.Data.Common.DbConnectionOptions.ParseInternal(Dictionary 2 parsetable, String connectionString, Boolean buildChain, Dictionary 2 synonyms, Boolean firstKey) at Microsoft.Data.Common.DbConnectionOptions..ctor(String connectionString, Dictionary 2 synonyms) at Microsoft.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at Microsoft.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at Microsoft.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at Microsoft.Data.SqlClient.SqlConnection..ctor(String connectionString) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerConnection.CreateDbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.get_DbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.Open(Boolean errorsExpected) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.<>c__DisplayClass18_0.<Exists>b__0(DateTime giveUp) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.<>c__DisplayClass12_0 2 synonyms) at Microsoft.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at Microsoft.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at Microsoft.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at Microsoft.Data.SqlClient.SqlConnection..ctor(String connectionString) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerConnection.CreateDbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.get_DbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.Open(Boolean errorsExpected) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.<>c__DisplayClass18_0.<Exists>b__0(DateTime giveUp) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.<>c__DisplayClass12_0 2.b__0(DbContext c, TState s) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerExecutionStrategy.Execute[TState,TResult](TState state, Func 3 operation, Func 3 verifySucceeded) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.Execute[TState,TResult](IExecutionStrategy strategy, Func 2 operation, Func 2 verifySucceeded, TState state) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.Execute[TState,TResult](IExecutionStrategy strategy, TState state, Func`2 operation) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.Exists(Boo lean retryOnNotExists) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.Exists() at Microsoft.EntityFrameworkCore.Migrations.HistoryRepository.Exists() at Microsoft.EntityFrameworkCore.Migrations.Internal.Migrator.Migrate(String targetMigration) at Microsoft.EntityFrameworkCore.Design.Internal.MigrationsOperations.UpdateDatabase(String targetMigration, String contextType) at Microsoft.EntityFrameworkCore.Design.OperationExecutor.UpdateDatabaseImpl(String targetMigration, String contextType) at Microsoft.EntityFrameworkCore.Design.OperationExecutor.UpdateDatabase.<>c__DisplayClass0_0.<.ctor>b__0() at Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute(Action action)

Keyword not supported: 'datebase'.

Answer 1

It is because of Typo in Connection string defined in Appsettings.json. to define Connection string in .NetCore we have write below line in Appsettings.json "ConnectionStrings": { "DefaultConnection": "Server=.;Database=BookListRazor;Trusted_Connection=True;MultipleActiveResultSets=True" }

And I wrote wrong strong text so EF didntunderstood how what to do.!
