"The selected file is not a valid solution file" error when trying to open source safe database

23.2k views Asked by Steph At 28 December 2024 at 05:40

I recently re-built my development machine which now uses windows 7. On this new machine, VS 2010 can no longer open sln files directly from SS 2005. These are valid 2010 solutions (orginally created witih VS 2010) that worked fine until I re-built my machine. My co-workers have the same setup and do not have this problem.

The message I get is "The selected file is not a valid solution file".

I've re-built many times and used many installs of VS and never had a problem opening sln's from SS using VS 05, 08 or 10. I've just never seen this before. My co-workers have not had this problem either

I have re-installed SS 2005 as well as the latest SS update but nothing works.

VS 2010 can open solutions from the file system just fine, so it must be a SS thing.

Any ideas?

In Visual Studio File>Project from Existing Code, then navigate to the Root folder containing the .sln and add all of it's contents to your new project. Everything should load in your new solution.

In my case, the message "The selected file is not a valid solution file" occurred when there were file names in my solutions that were too long for the path where i wanted to download the solution. Putting the solution folder directly under the C:\ drive or a folder short to the C-drive solved my problem.

**NEBEZ** · Answer 3 · 2020-09-15 08:40:05

For me this solution worked perfect:

Create new project in visual studio(new project name should be same as main projct name) and delete any default created project in new solution. now go to new project location and copy .sln file. go to main project location and delete .sln file and paste copied .sln file and open, than rebiuld solution again.

Note: if faced any erorr about project manifest you can edit .csproj(by notepad) and delete any tag related to manifet and save. again reload solution.

For me this worked.

you have to change permission

right click on parentfolder=>properties => security => (edit) button => (add) button => (advanced) button => (find now) button=> and now select : Everyone => ok => ok => Now you have to allow it full control=> Full control = Allow
=> ok

now let it to apply for all of subfolders and files

FINISHED

I've had a similar error message after installing Windows 7. Turns out that some features of Visual Studio were not yet installed. It might have been a service pack or EF4. Once that was installed, I was able to open the solution file. Then, I was also getting "The project type is not supported by this installation" until I installed some other updates, like for MVC3.

I presume that the solution file had information that the un-patched Visual Studio did not recognize.

I went into the containing folder, I opened the .csproj file in visual studio which caused the solution to reload and I no longer had the error.
