What is DBML file?

The file with the extension DBML is the Developer Files file type. The creator of this file is Microsoft. Developer Files consists of 1205 similar files. Visual Studio OR Design Format is most often found on 3 operating systems. These systems consist of Linux, Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use Microsoft Visual Studio to handle this file. This is a program created by Microsoft Corporation. This file type can also be opened by 7 other programs. The Windows Notepad, Nvu, NotePad++ text editor, Microsoft SQL Server programs will also handle the file when the Microsoft Visual Studio program does not fulfill its role.

How to open DBML file?

The most common problem when using Visual Studio OR Design Format is that a specific DBML is not associated with the program. Thus, when you open DBML, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the DBML file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Visual Studio

The first step is to check if the computer has the Microsoft Visual Studio program installed. The easiest method is to use the system search engine by entering the program name Microsoft Visual Studio in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file DBML.

Step 2. Create association of Microsoft Visual Studio with DBML files

If the application is or has been freshly installed, but the DBML file still does not use the Microsoft Visual Studio program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DBML file with the Microsoft Visual Studio application.

Step 3. Update Microsoft Visual Studio to the latest version

The fault may also lie with the Microsoft Visual Studio program, it is possible that Visual Studio OR Design Format requires a newer version of the program. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the DBML file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to DBML files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the DBML file that we want to open. As a result of the scan, sometimes it is not possible to recover DBML files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the DBML files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair DBML file corruption. You can restore the file from a backup or use Microsoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file DBML except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DBML file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file DBML to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
