问题 I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again? This

问题 I have a question about "Data connections" in azure. I have an App Service. I published my API app there. In my app I have connection strings (I need to work with databases). Among numerous settings for my app I saw a "Data connections" item: There you can add new connection (server, login, password).

问题 Got a problem with reading Excel files in C# The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine. , same for 'Microsoft.ACE.OLEDB.12.0' . that only occurs when I run my app on IIS.

It looks like there are 2 types of solutions to this problem: either install something (preferred) or switch to 32bit mode. I'd
