ASP.NET 2.0 Troubleshooting tips!

Oflate, while converting our 1.1 applications to 2.o, we have encountered common weird errors…. The following are solutions of some common issues in 2.0 applications :

Error#1 : ” The project file ‘ ‘ has been either renamed or is no longer in the solution”

Solution: We received the above error whenever we made changes to source files of the pages or .cs files which are referred in our application. Open the property pages under the website and remove all the incorrect references. Add the proper references back and try to compile again.

Error#2: “System.InvalidCastException’ System.Data.SqlClient.SqlInternalConnectionSmi {System.InvalidCastException} ”

Solution: We received the above error when we tried to execute a sql command and retrieve the values of the sql query using data reader.  Type cast the variable with the data type.  For example: string value=(String) datareader1.GetValue(0);

Error#3: “System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it “

Solution: We received the above error when we tried to fetch some data through a webservice in our application .This means the the sql server database is refusing the connection. There are two solutions to this problem:

a. Replace the data source in the connectionstring with the machine IP Address or

b. Remove the web reference (in case of webservice) and add again.

keep watching this space for more solutions!!!
