TFS 2010 VS2012 Get latetest version => File is corrupt, Works Ok in vs2010

Question

Have a project in VS2012 when SEVERAL users, not all users, do a get latest version on the solution they receive error:

c:\...\ somefile.cs: The downloaded file is corrupt. Please get the file again.

For a work around they are opening vs10 and doing a get latest version from the source code explorer and then working on the project in VS12.

Answer 4

Each of us is running

• Windows 7
• VS Professional 2012 Version 11.0.50727.1 RTMREL
• When get latest or get specific version at least one file will fail as corrupt

It appears I am getting event log errors from TFS as follows:

My coworker is receiving the same error message in VS but has no event log errors.

Answer 5

I have attempted to:

    delete my local workspace
    Run a Repair on VS 2012
    Clear TFS cache
    Add a new workspace

Still receiving the error.

No longer getting the event log errors though.

Answer 6

nothing in event log on workstation or server

Answer 7

Are you running "get latest" from the command line, since the event log is showing TFSShellExt?

Answer 8

No.  We tried get latest => errors

We tried Advanced Get Specfic Version, Latest, Overwrite, Overwrite => errors

The later does the same as the command line.

How long do you think it might take. Because our TFS is corrupt some users can't develop.  We can't deploy any projects to production.  We are pretty much dead in the water.

Answer 11

If you have an urgent issue of this nature it is always best to open a support case:  http://support.microsoft.com/default.aspx?id=fh;en-us;offerprophone. In fact, troubleshooting this particular problem is beyond what we can do here in the forum. This will require 1:1 live support. If you cannot determine your answer here or on your own, consider opening a support case with us.

Answer 12

We opened a paid support incident a week ago.  Unfortunately, they are still thinking about it. :(

If you know any way to get support from the MS TFS team or could recommend a 3rd party vendor who is smart, we could use it.  All of our developers are down and we can't deploy apps.  That gets real expensive real fast.

Answer 13

Do you use a proxy server? If not, go to your TFS 2010 server, and find a directory like this:

C:\Program Files\Microsoft Team Foundation Server 10.0\Application Tier\Web Services\_tfs_data\

Go there, and type rd /s /q . (make sure to not delete _tfs_data itself of course).

Then try your download again - see if it works.

Answer 14

Chuck, I've located your support case and am processing an escalation. In future if you have an urgent issue like this, that is costing you money and where you have developers down... please don't wait. Please explain your situation and make sure the support professional understands the gravity of the problem. We have processes in place to expedite service where it is warranted, but we need to know that it is. I've reviewed the case notes and it doesn't look like that was communicated very well, so the case was not given the heightened attention it may have warranted had we known.

Answer 15

Hi, 

We are getting a similar issue here where can't load files from TFS2012 from a specific changeset. Visual Studio 2010 downloads the files with content from who knows where (eg it fills a .cs file with xml from some other part of the project), Visual Studio 2012 attempts to download the file then gives the same error "The downloaded file is corrupt. Please get the file again."

Looking at the file in Web Access it shows the correct versions of the file so I used that to download the 4 files that Visual studio corrupted as it downloaded, make a whitespace change to all and then checked in again. All good now but definitely a bug somehere in the Visual Studio TFS 2012 data interface methinks...

If you get an answer on this from MS on this, it would be great if you could pass it on!

Thanks

Adrian 

Answer 16

MS has been working on it for weeks, no solution so far.

They had a similar issue with one customer who was using some AntiVirus program I never heard of, don't remember the name.  That is not our issue as even if we turn off the AV, it still occurs.

Answer 17

I can confirm the same Problem in VS2012, with the same Work-around, which is to just do the Get Latest in VS2010.  Multiple Devs with the same problem.  We are connecting to a TFS2010.  One additional note I may be able to add is that we have FIPS enabled at the OS level via Group Policy.

Answer 18

We had a paid support in with MS for over a month.  No real resolution.  We finally gave up, got tired of talking.   It is THOUGHT vs10 computed hashes of file transfers but did not use them. Sometimes hashes were wrong. VS12 uses them. Only work around seems to be do a get specific version/latest with vs10.  Edit them with vs12 (add a space), then check them in.

Answer 19

Chuck, please mail me directly on this ASAP: TREVORH at MICROSOFT. If you are working with Gloria, the last we head from her on this case was that the issue is no longer happening. That was Oct. 26th.

Dead in the water too.

Help~~~

Answer 21

Calvin - please open a support case as Trevor explained, we can't troubleshoot this on the forum:

http://support.microsoft.com/default.aspx?id=fh;en-us;offerprophone. In fact, troubleshooting this particular problem is beyond what we can do here in the forum. This will require 1:1 live support. If you cannot determine your answer here or on your own, consider opening a support case with us.

Answer 22

This is a common problem in TFS that MS knows of but chooses to or can't easily fix.  Apparently the hash algorithm for files was not really used in vs10 and was not computed the same way as it is in vs12.  So you need to get the file in vs10 and then change it vs12 and save it. Now the hash will be correct. 

We had to do this for about 50 files.

It took over a month with:

Christopher Cooper & Trevor Hancock from Microsoft Support to find the problem, but no automated fix.
