Amazon.Runtime.AmazonServiceException: Cannot find credentials

We developed the WebService application in vs 2010 using the AWS SDK, which connects to AWS SNS.

This works great when we directly launch the VS 2010 development studio, but when we publish a web service for a local IIS or dedicated web server, it fails with the following error messages.

Amazon.Runtime.AmazonServiceException: Unable to find credentials

Create a credential file on any path where you can access this path from the web service application Ex. C: \ awsfile \ Credentials but remember, don’t give any extension to this file. The file should contain the following data.

[default]
aws_access_key_id=[your_access_key]
aws_secret_access_key=[your_secret_key]

appsetting Web.config:

<appSettings>
<add key="AWSProfilesLocation" value="C:\awsfile\credentials" />
<add key="AWSRegion" value="us-east-1" />
</appSettings>
