oracle.manageddataaccess.client throws exception when try to create the connection from OWIN stand alone web api application.
return new OracleConnection(
new OracleConnectionStringBuilder()
{
DataSource = _server,
Pooling = _poolEnabled,
MinPoolSize = _minPoolSize,
MaxPoolSize = _maxPoolSize,
UserID = _username,
Password = _password,
ConnectionTimeout = _timeout
}.ToString()
);
The code snippets work outside OWIN app. But when called inside owin context it throws exception The type initializer or 'OracleInternal.Common.ProviderConfig' threw an exception, and 'Microsoft.Owin.OwinContext' in assembly is not marked as serializable.
The detailed exception is a follows,
System.TypeInitializationException was unhandled by user code
HResult=-2146233036
Message=The type initializer for 'OracleInternal.Common.ProviderConfig' threw an exception.
