Error:
Failed to register URL “http://localhost:XXXX/” for site “SITE NAME” application “/”. Error description: The process cannot access the file because it is being used by another process. (0x80070020)
**XXXX = port number
Reason for this error:
This error happens to me because I was using same solution for different project. I copied the solution and created another one in different location.
I have done several another projects in same way, however, I didn’t face this error earlier. I think, the localhost with the port has been researved for the previous actual solution. Since I created seperate project in TFS and then clone the solution local location with same solution name in different location.
Resolution:
Solutions Explorer
Right click on project select Unload project
Again Right click and select Edit ProjectName.csproj
remove these 3 lines
<DevelopmentServerPort>0</DevelopmentServerPort>
<DevelopmentServerVPath>/</DevelopmentServerVPath>
<IISUrl>http://localhost:62940/</IISUrl>Save and reload the project
Then, you will get new port for the project.
If you find any another solution, please comment.
Spot on with this write-up, I seriously feel this amazing site needs a great
deal more attention. I’ll probably be back again to read through more, thanks for the information!
