FSPROJ file is associated with Microsoft Visual F# software application. This file format is used as a project file which provides the workspace for user.
The project file stores the source code which is added in it along with the different tools that are used on that source code. FSPROJ file not only stores the user working progress but also saves user preferences for that specific project. All the required information to completely define a project in workspace is stored in single FSPROJ file. This file can be later on used to compile the final source code and view the final result.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .FSPROJ file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .FSPROJ file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .FSPROJ file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
