ASP.Net Website project compilation errors when using Oracle 12c Client 12.2 64 bit

user10395468Aug 22 2019 — edited Aug 22 2019

Hi all,

i have a Asp.NET website project which is now getting migrated to use Oracle 12C client 12.2 64 bit ( Oracle.DataAccess.dll 12.2 64 bit ) version and target .net framework 4.7.2.

i replaced all System.data references to the above Oracle.DataAccess.dll version . Did code modifications to use OracleDataAccess instead of System.data.

And tried to build the website from Visual studio 2017 IDE . Its throwing below compilation error . it doesn't says any file or line no # .

Severity	Code	Description	Project	File	Line	Suppression State
Error		Object reference not set to an instance of an object.

Also, if i open any aspx page in the website using Visual Studio Solution explorer , its showing various errors for each and every control defined the page.

Some of the error codes - BC30506, BC30002, BC30451 etc.

Anyone came across with these type of issues when using Oracle.DataAccess.dll 12.2 64 bit in a Website project.

Any help is really appreciated.

Thanks

Neena
