How to open CSDL files

Did your computer fail to open a CSDL file? We explain what CSDL files are and recommend software that we know can open or convert your files.

What is a CSDL file?

CSDL files are ADO.NET Conceptual Schema Definition Language files, which you can read more about below.

The CSDL file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a CSDL opener may not be able to open all kinds of CSDL files. In this case, though, we only know of one specific use.

ADO.NET Conceptual Schema Definition Language

Through our analysis of CSDL files, we know that one use of the format is ADO.NET Conceptual Schema Definition Language. We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.

We have not verified any programs yet that works with this specific format. If you know any, please use the 'Suggest a program' link below. Thanks!
