Getting many errors when trying to add changeset url from local TFS instance

lic class TypedDataContext : JsonDataContextBase {

	public IEnumerable<LINQPad.User.TestInput.Test> Test { get { return GetTextJsonInput<LINQPad.User.TestInput.Test>("7a3a553d-d404-4d95-8e50-2401723a3dac"); }}

	public IEnumerable<.> s { get { return GetUrlParameterlessInput<.>(@"http://server:8080/tfs/defaultcollection/App Modernization/_apis/tfvc/changesets", new List<Tuple<string,string>> { Tuple.Create("Accept","application/json; text/json") }); } }

}

Here is json, which works if used at text type:

{"count":1,"value":[{"changesetId":358,"url":"http://server:8080/tfs/DefaultCollection/App%20Modernization/_apis/tfvc/changesets/358","author":{"id":"f0b23e2a-04d4-4a20-86f6-32970a135280","displayName":"Alexander Kachalkov","uniqueName":"domain\user","url":"http://server:8080/tfs/defaultcollection/_apis/Identities/f0b23e2a-04d4-4a20-86f6-32970a135280","imageUrl":"http://xsupapp15zpts12:8080/tfs/DefaultCollection/_api/_common/identityImage?id=f0b23e2a-04d4-4a20-86f6-32970a135280"},"checkedInBy":{"id":"f0b23e2a-04d4-4a20-86f6-32970a135280","displayName":"Alexander Kachalkov","uniqueName":"domain\user","url":"http://server:8080/tfs/defaultcollection/_apis/Identities/f0b23e2a-04d4-4a20-86f6-32970a135280","imageUrl":"http://server:8080/tfs/DefaultCollection/_api/_common/identityImage?id=f0b23e2a-04d4-4a20-86f6-32970a135280"},"createdDate":"2016-09-06T07:02:38.34Z","comment":"Created team project folder $/App Modernization via the Team Project Creation Wi","commentTruncated":true}]}

P.S. I think it would be easier to edit connection file directly rather than through GUI :)
