I'm trying to learn about SQL databases and use them for my asp.net app sine I cant get the hang of MySQL in ASP. Every time I go to create a new SQL Database it saids: Would you like to place it in the App_Data folder basicly and I say yes. Then the error:
Unable to find DbProivderFactory for type System.Data.SqlClient.SqlConnection
Hi Clanstyles,
Based on the error message, I think the provider factory was not installed properly on you machine. Or the configuration files might not be written correctly.
Please try the following:
1. Open machine.config file under C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG
2. Check the nodes under configuration/system.data/DbProviderFactories to see if all the provider has been installed successfully. It has to look like this.
<DbProviderFactories>
<add name="Odbc Data Provider" invariant="System.Data.Odbc" description=".Net Framework Data Provider for Odbc" type="System.Data.Odbc.OdbcFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

</DbProviderFactories>
HTH.
