How to open FSPROJ file?

An often recurring problem with Visual F# Project Format is that FSPROJ is not associated with the correct program file. Thus, when you open FSPROJ, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the FSPROJ 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

An often overlooked issue is to make sure that Microsoft Visual Studio is installed on the computer. To do this, enter the name Microsoft Visual Studio into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support FSPROJ files.

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

If the application is or has been freshly installed, but the FSPROJ file still does not use the Microsoft Visual Studio program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the FSPROJ 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The fault may also lie with the Microsoft Visual Studio program, it is possible that Visual F# Project Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the FSPROJ file. The only repair option is to download the file again.
The most common cause here is computer viruses. 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 FSPROJ file that we want to open. Sometimes virus-infected FSPROJ files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the FSPROJ 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged FSPROJ files. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program can also signal the fact of encryption. The encrypted FSPROJ files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move FSPROJ to a different directory.
This can happen on a file that does not support multiple access. In this case, the FSPROJ file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the FSPROJ file again. However, some background programs may block the FSPROJ file while scanning. If this does not work either, restart the device.
