Unable to determine the workspace. - Error after update to Rider 2018.2

[dillius]

Can no longer retrieve latest from TFS after updating Rider to 2018.2. Worked fine prior, during the same day. On latest 1.1.150 version of the plugin. Not sure if the VSO plugin needs an update or if this is a bug caused by Jetbrains.

Error:An argument error occurred: Unable to determine the workspace. You may be able to correct this by running 'tf workspaces /collection:TeamProjectCollectionUrl'.

I am also getting this error on rider.

Sometimes this may be caused by Visual Studio TFS workspace being imported into a portable (TFC-CLC) one. The recommendation here would be to try running tf workspaces /collection:TeamProjectCollectionUrl in your console as the command-line cliend suggests, e.g.

tf workspaces /collection:http://myserver:8080/tfs/DefaultCollection

It could help with remapping the workspace.

While it was unlikely the original way or reproducing the issue, I've found at least some way to reproduce that.

Stage 1: Reproduce #201

First of all, you'll need to obtain version of the plugin where #201 was easily reproducible. For example, install Rider 2019.1.1 where version 1.151 of the Azure DevOps plugin is bundled.

1. Checkout any TFVC project containing .NET solution
2. Add an xunit test project
3. Press the Refresh button in the local changes list
4. Make sure no changes is shown: here you go, you've reproduced Local Changes aren't detected in TFVC when the project contains external files #201

Stage 2: Reproduce #173

Now, even if you update the plugin to 1.152 (the latest version currently), and then go to the Incoming tab in the Version control tool window, you'll be unable to get any changes: pressing the Update Changes button will only show the Messages window with the error message:

The issue won't be fixed by tf workspaces, because it has other root cause. We should port the same fix we used for #201, but not only for tf status command, but for tf get, too.
